VR Wars: The RX 6800 XT vs. the RTX 3080 – 15 Games Performance benchmarked using the Vive Pro

This review presents a fifteen-game VR performance showdown between the RX 6800 XT and the RTX 3080 using the Vive Pro and FCAT VR.  We have also added Assetto Corsa Competizione and Into the Radius for this review.

Since we posted our original review, we have benchmarked more than 20 VR games for our follow-up reviews over the past nearly four years.  We have also compared FCAT-VR with our own video benchmarks using a camera to capture images directly from our HMD’s lenses.  For BTR’s VR testing methodology, please refer to this evaluation.

We currently benchmark fifteen VR games using the Vive Pro.  BTR’s testing platform is an overclocked Intel Core i9-10900K, an EVGA Z490 FTW motherboard, and 32 GB of Vulcan Dark Z DDR4 at 3600MHz on a clean install of Windows 10 64-bit Pro Edition using NVIDIA’s latest GeForce Game Ready Driver, 457.30, and AMD’s Adrenalin Software 20.11.2 public launch drivers for the RX 6800 XT.

It is important to be aware of VR performance since poorly delivered frames can make a VR experience unpleasant.  It’s also important to understand how we accurately benchmark VR games using FCAT-VR as explained here.  But before we benchmark our fifteen VR games, check out our Test Configuration below.

Since we received our RX 6800 XT after it launched, we tested 9 pancake games to validate its performance and we present it below in advance of our full review versus a PowerColor Red Devil RX 6800 XT using 35+ games next week.

The two cards are fairly evenly matched and the performance is close in many cases even though we only had time to test 9 games.  However, this review will focus on VR performance.  Up next is our test configuration which are the same for PC games as PC VR games.

The Unreal 4 engine is a very popular engine for VR development, and seven of our thirteen test games are created with it.  The Creation and Unity engines are each used for two games, while the COBRA, No Man’s Sky, Source, and Madness engines are each represented by one game.

It is important to remember that BTR’s charts use frametimes in ms where lower is better, but we also compare “unconstrained framerates” which shows what a video card could deliver (headroom) if it wasn’t locked to either 90 FPS or to 45 FPS by the HMD.  In the case of unconstrained FPS which measures just one important performance metric, faster is better.

Let’s individually look at our fifteen VR games’ performance using FCAT VR.  All of our games were benchmarked at 100% SteamVR resolution or higher (as noted), although some games were also set in-game to a higher resolution or increased pixel density as described for each game, as we compare the RX 6800 XT with the RTX 3080.

First up, ARK Park.

ARK Park 

ARK Park is a single or multiplayer VR adventure game set in a dinosaur theme park, and it allows gamers to interact with a few of the dinosaurs in ARK: Survival Evolved.  The idea is to explore your own “Jurassic Park”, study genetics, raise baby dinosaurs from eggs, ride and paint them, and even defend the park against attacking dinosaurs in a wave shooter segment.  It’s not a great game with small maps, but its visuals are still worth benchmarking.

ARK: Park has very few adjustable settings so we benchmark it using its highest preset.  We also used SteamVR to increase the resolution from 100% to 200%.

Here are the performance results of our two competing cards using FCAT VR’s generated chart.

Here are the details are reported by FCAT-VR:

The RX 6800 XT delivered 175.98 unconstrained FPS with 1 dropped frame and 2 frames were synthesized.  In addition, it suffered 1 Warp Miss.

The RTX 3080 achieved 267.52 unconstrained FPS with 2 dropped and 4 synthetic frames together with 2 warp misses.

There isn’t any difference playing on either card at our chosen settings using 200% Super Resolution in SteamVR as ARK Park is built on the Unreal Engine and it is just not very demanding.  However, the RTX 3080 has significantly more performance headroom than the RX 6800 XT.

Next up, Assetto Corsa Competizione.

Assetto Corsa Competizione

BTR’s sim/racing editor, Sean Kaldahl created the replay benchmark run we use for both the pancake game and the VR game.  It is run at night with lots of geometry, and the lighting effects of the headlights, taillights, and everything around the track looks spectacular.

Just like with Project CARS, you can save a replay after a race.  Fortunately, the CPU usage is the same between a race and its replay so it is a reasonably accurate benchmark using the Circuit de Spa-Francorchamps.
Sean believes that iRacing may be more accurate or realistic, but Assetto Corsa Competizione has some appeal because it feels more real than many other racing sims.  It delivers the sensation of handling a highly-tuned racing machine driven to its edge.

Here are the frametimes.

Here are the details are reported by FCAT-VR:

The RX 6800 XT delivered 126.49 unconstrained FPS with no dropped frames or Warp misses but it needed 125 synthetic frames.

The RTX 3080 delivered 138.97 unconstrained FPS together with 2 dropped and 181 synthetic frames along with 2 Warp misses.

The experience is similar for both cards although the RTX 3080 has about 10% more performance headroom for potentially increasing individual in-game visual settings.

Next, we look at Boneworks.


Boneworks is a rare game that couples a fair single player campaign with an incredible sandbox and next generation VR physics interactive tour de force.  We benchmark using the ‘Time Tower’ level.

Boneworks made on the Unity engine has average to very good visuals and it particularly benefits by allowing for high levels of MSAA up to 8X which we use for benching. We also enable ambient occlusion and use the highest settings, and in addition, we set SteamVR’s resolution to 160%.

Here are the frametimes.

Here are the details are reported by FCAT-VR:

The RX 6800 XT delivered 210.52 unconstrained FPS with no dropped and no synthetic frames.

The RTX 3080 delivered 190.82 unconstrained FPS also with 5 dropped and 7 synthetic frames along with 5 warp misses.

As with ARK Park, there isn’t any difference playing on either card at our settings are not very demanding although the RX 6800 XT has more performance headroom.  For GeForce cards, we recommend using NVIDIA’s VRSS for more visual improvement with only a minor performance penalty.

Let’s check out Elite Dangerous next.

Elite Dangerous

Elite Dangerous is a popular space sim built using the COBRA engine. It is hard to find a repeatable benchmark outside of the training missions.

A player will probably spend a lot of time piloting his space cruiser while completing a multitude of tasks as well as visiting space stations and orbiting a multitude of different planets (~400 billion).  Elite Dangerous is also co-op and multiplayer with a very dedicated following of players.

We picked the Ultra Preset, and this time, we set the Field of View to its maximum.  Here are the frametimes.

Here are the details are reported by FCAT-VR:

The RX 6800 XT delivered 141.80 unconstrained FPS with no Warp Misses and 0 dropped frames, and 18 of its frames had to be synthesized.

The RTX 3080 delivered 148.09 unconstrained FPS with no Warp Misses or dropped frames, but it required 3 synthetic frames.  The experience playing Elite Dangerous at Ultra settings is not perceptibly different on either video card.

Let’s continue with Fallout 4.

Fallout 4

Fallout 4 uses the Creation Engine, and Bethesda has dropped all support for it so it remains unoptimized although there are mods that may be helpful.  It’s pretty hard to use the Index controllers with it, so we use the Vive wands instead for this game.  We benchmark at its highest settings and with TAA.  All Fade settings are set to their maximums.

Fallout 4 had some issues on both cards as it is still an unoptimized mess abandoned by its publisher – but it is playable and an amazing full-game experience.

Here is the frametime plot for Fallout 4.

Here are the details are reported by FCAT-VR:

The RX 6800 XT delivered 152.52 unconstrained FPS with 6 Warp Misses and 259 dropped frames (5%), although none of its frames had to be synthesized.

The RTX 3080 delivered 145.20 unconstrained FPS with 7 Warp Misses and 7 dropped frames, and it required 173 (3%) synthetic frames.

Dropped frames are more noticeable than synthetic frames and the RTX 3080 delivers a smoother VR experience for Fallout 4 although it also suffered warp misses.

Next we look at Half Life: Alyx:

Half Life: Alyx

Half Life: Alyx uses an adaptive/dynamic scaling algorithm which uses a card’s performance headroom to subsample in demanding scenes and to supersample in less demanding scenes. We used its console commands to lock the SteamVR resolution to 200% so that it did not supersample or subsample.

Here is the frametime plot for Half Life Alyx.

Here are the details as reported by FCAT-VR.

The RX 6800 XT delivered 145.62 unconstrained FPS with 43 dropped but no synthetic frames nor any warp misses.

The RTX 3080 delivered 158.82 unconstrained FPS and with 2 dropped and 14 synthetic frames with 2 warp misses.  Half Life Alyx isn’t particularly demanding until the Super Resolution increased to beyond 150% in SteamVR settings, and the game will subsample or supersample as needed.

Next, we look at Hellblade: Senua’s Sacrifice.

Hellblade: Senua’s Sacrifice

Hellblade: Senua’s Sacrifice is a visually impressive game using the Unreal 4 engine.  It is a dark and disturbing game that is far more intense in VR than the pancake version. We benchmark at its very highest settings and with TAA, and we also increased the resolution to 170% in-game.

Here is the frametime plot for Hellblade: Senua’s Sacrifice.

Here are the FCAT-VR details.

The RX 6800 XT delivered 96.83 unconstrained FPS with 33 dropped and 1559 synthetic frames (24%) along with 33 Warp Misses as it could not deliver 90 FPS to the HMD at 170% resolution.

The RTX 3080 delivered 109.56 unconstrained FPS with 3 dropped and 94 synthetic frames (1%). It also suffered 3 Warp Misses.

Hellblade only becomes demanding after the in-game resolution is set to above 150% although it looks great. Unfortunately, 170% Super Resolution is too demanding for the RX 6800 XT and it suffered Warp Misses and dropped frames.

Next we look at Into the Radius.

Into the Radius

Into the Radius is a hardcore single player stealth survival adventure/exploration game, and it pays homage to the S.T.A.L.K.E.R. series by being set in the dangerous large open world of the Pechorsk Exclusion Zone.

Into the Radius has decent visuals using Unreal Engine 4 that really add to its spooky and intense atmosphere, and its performance demands on the video card are also higher since its a huge open world game with a decent draw distance.

There are no user options for changing individual graphics settings other than High, Medium, and Low presets. There is also a slider to drop or subsample the resolution down to 65%, or to increase the resolution to 110%.  We benchmarked our two cards at High Quality and with 110% resolution.

Here is the frametime plot for Into the Radius.

Here are the FCAT-VR details.

The RX 6800 XT delivered 135.64 unconstrained FPS with 11 dropped frames, but no warp misses were reported and no synthetic frames needed to be synthesized.

The RTX 3080 delivered 151.01 unconstrained FPS with 3 dropped and 7 synthetic frames. However, it suffered 3 Warp Misses.  Both video cards delivered a similar experience although the RTX 3080 has more performance headroom.

Into the Radius becomes demanding after the resolution is set above 100%.

Next, we will check out another demanding VR game, No Man’s Sky.

No Man’s Sky

No Man’s Sky is an action-adventure survival single and multiplayer game that emphasizes survival, exploration, fighting, and trading.  It is set in a procedurally generated deterministic open universe, which includes over 18 quintillion unique planets using its own custom game engine.

The player takes the role of a Traveller in an uncharted universe by starting on a random planet with a damaged spacecraft equipped with only a jetpack-equipped exosuit and a versatile multi-tool that can also be used for defense. The player is encouraged to find resources to repair his spacecraft allowing for intra- and inter-planetary travel, and to interact with other players.

Here is the No Man’s Sky Frametime plot.  We set the settings to High which is above Enhanced but below Ultra, and we also set the anisotropic filtering to 16X and upgraded to FXAA+TAA.

Here are the FCAT-VR details of our comparative runs.

The RX 6800 XT delivered 108.90 unconstrained FPS with 4 warp misses and 187 (3%) dropped frames, although none of its frames had to be synthesized.

The RTX 3080 delivered 126.48 unconstrained FPS with no dropped frames and no warp misses, and it only required 39 (1%) synthetic frames.

The RTX 3080 edges out the RX 6800 XT and delivers more performance headroom and a smoother experience.  We do not recommend using Ultra settings for either card, however.

Next, we will check out another VR game, Obduction.


Obduction is considered  to be the spiritual successor to Myst and Riven. It is an adventure game developed by Cyan Worlds using the Unreal 4 engine and it has very good visuals.  There is an emphasis on puzzle solving which get more and more difficult as a player progresses.

Here is Obduction’s frametime plot.

Here are the details.

The RX 6800 XT delivered 112.83 unconstrained FPS with 3 dropped frames, 191 synthetic frames (3%), and 3 warp misses.

The RTX 3080 delivered 130.54 unconstrained FPS and with 3 dropped frames, 10 synthetic frames and 3 warp misses.  The experience playing Obduction is similar on both cards.

Next we will check out another demanding VR game, Project CARS 2 that we like better than Project CARS 3.

Project CARS 2

There is a real sense immersion that comes from playing Project CARS 2 in VR using a wheel and pedals.  It uses its in-house Madness engine, and the physics implementation is outstanding.  We are disappointed with Project CARS 3, and will continue to use the older game instead for VR benching.

Project CARS 2 offers many performance options and settings and we prefer playing with SMAA Ultra.

Project CARS 2 performance settings

We used maximum settings including for Motion Blur although it looks best to us with on Low or Medium.  For lesser cards, we would also recommend lowering grass and reflections to maximize framerate delivery as motion smoothing or reprojection tends to cause visible artifacting.

Here is the frametime plot.

Here are the FCAT-VR details.

The RX 6800 XT delivered 123.10 unconstrained FPS, with 5 dropped frames, 5 warp misses but 210 of its frames (2%) had to be synthesized.

The RTX 3080 delivered 117.70 unconstrained FPS with 2 dropped frames, 2 warp misses, but it only required 18 synthetic frames.  The experience playing Project CARS 2 on our maximum settings is similar on both cards although the RX 6800 XT requires more frames to be synthesized.

Let’s benchmark Skyrim VR.

Skyrim VR

Skyrim VR is an older game that is no longer supported by Bethesda, but fortunately the modding community has adopted it.  It is not as demanding as many of the newer VR ports so its performance is still very good on maxed-out settings using its Creation engine.

We benchmarked Skyrim VR using its highest settings, and we also increased the resolution to its in-game maximum.

Here are the frametime results.

Here are the details of our comparative runs as reported by FCAT-VR.

The RX 6800 XT delivered 134.93 unconstrained FPS with no dropped frames, no synthetic frames, and no warp misses.

The RTX 3080 delivered 158.87 unconstrained FPS with 5 dropped frames, 5 synthetic frames, and 5 warp misses.  Of course, many players would prefer adding more mods to the game rather than increasing the resolution, and the RTX 3080 gives a bit more performance headroom than the RX 6800 XT.

Let’s check out Subnautica next.


Subnautica uses the Unity engine.  As the sole survivor of a crash landing, the player ventures into the depths of a visually impressive alien underwater world. Here you can explore, craft equipment and build bases, pilot underwater craft, and solve mysteries all while attempting to survive a hostile environment.  It is an unoptimized mess, but the VR experience is well worth it.

We benchmarked Subnautica using its highest settings plus TAA, but we left its resolution at 100%, and here are the frametime results.

Here are the details.

The RX 6800 XT delivered 110.88 unconstrained FPS with no Warp Misses, and although it required no synthetic frames, it reported 2001 dropped frames instead.

The RTX 3080 delivered 102.13 unconstrained FPS with no dropped frames, no warp misses, but 37% (2380) of its frames had to be synthesized.

The experience playing Subnautica using its highest settings is not ideal as it doesn’t appear to be very well optimized and there are obvious stutters at times which may also be driver related. However, the experience using the RX 3080 is smoother as the RX 6800 XT dropped frames instead of synthesizing them.

Next up, The Vanishing of Ethan Carter.

The Vanishing of Ethan Carter

The Vanishing of Ethan Carter is an older game which is built on the Unreal 4 engine and it still boasts amazing visuals although it is not demanding.  Although it is considered by some to be a walking simulator, it is also an excellent detective game with great puzzles.  But be aware that its style of locomotion tends to make some of its players VR sick.

There are just a few in-game graphics options available, so we set 100% resolution in-game with TAA and then set SteamVR’s resolution to 200%.

Here is the frametime plot.

Here are the FCAT-VR details.

The RX 6800 XT delivered 250.76 unconstrained FPS with no dropped frames, no warp misses and no synthetic frames.

The RTX 3080 delivered 258.67 unconstrained FPS with 8 dropped frames, 8 warp misses, and 8 synthetic frames.

Although it is a beautiful game visually, The Vanishing of Ethan Carter isn’t particularly demanding even after the Super Resolution is increased to 200% using SteamVR.  The experience playing on both cards is similar although the Warp Misses and dropped frames did impact the experience using the RTX 3080.

Last up, The Walking Dead: Saints & Sinners.

The Walking Dead: Saints & Sinners

The Walking Dead: Saints & Sinner is the last of BTR’s 15 VR game benching suite.  It is a first person survival horror adventure RPG with a strong emphasis on crafting.  Its visuals using the Unreal 4 engine are outstanding and it makes good use of physics for interactions.

We benchmarked Saints and Sinners using its highest settings, but this time we increased the Pixel Density to 150% in game.  Here is the frametime chart.

Here are the details as reported by FCAT-VR.

The RX 6800 XT delivered 116.32 unconstrained FPS with 18 dropped frames and 18 warp misses, and 213 (3%) of its frames had to be synthesized.

The RTX 3080 delivered 120.28 unconstrained FPS with 2 dropped frames and 2 Warp Misses, and it required 46 (1%) synthetic frames.

The experience playing The Walking Dead: Saints & Sinners using the in-game maximum settings and highest Pixel Density is similar between both video cards although the RTX 3080 delivers a smoother experience.

Let’s look at our overall Unconstrained Framerates Chart.

Unconstrained Framerates

The following chart summarizes the overall Unconstrained Framerates (the performance headroom) of our two cards using fifteen test games and four synthetic benches: Superposition, VRMark’s Cyan and Blue Rooms, and the OpenVR benchmark.  Higher is better.

Synthetic benchmarks are only useful for ranking cards.  They don’t predict how any game will actually play in VR on any particular video card.

The RX 3080 delivers higher unconstrained frames in 11 out of 15 games over the RX 6800 XT in this one important performance metric.  We don’t give percentages of change or percentages of increase between competing cards since unconstrained framerates are just one metric of performance headroom that is useless without the accompanying frametime charts.

Let’s check out our conclusion.


It is great to see AMD delivering a card that is performance competitive with the RTX 3080.  However, the RX 6800 XT only delivers higher unconstrained framerates in 4 of the 15 games we benchmarked.  In addition, several of the FCAT VR frametime plots indicate the RTX 3080 delivers a smoother experience.  From our preliminary PC gaming benchmarks using just 9 games, so far, the RX 6800 XT appears to be faster in pancake gaming than in VR relative to RTX 3080 performance.

We will continue to follow up VR performance between the RX 6800 XT and the RX 3080 and will add other cards into the mix as we check back to see if future drivers address performance and stability issues.

The next review will compare the performance of the RTX 3080 versus the RX 6800 XT reference version in 35+ games, and will also compare ray tracing performance and features to help determine value.  In addition, we will introduce PowerColor’s Red Devil RX 6800 XT and also compare its performance and features next week.  The reference RX 6800 XT has sold out worldwide and Radeon gamers are eagerly anticipating AMD’s partner launches.

In addition, we will have another new hardware review the following week that no one will want to miss!

Stay tuned to BTR!

Happy VR Gaming!



      • I know why AMD didn’t send you a sample. Because the 6800 is absolutely miserable in VR, I have one and it is dog s**t slow. Frame drops in the 1,000’s GPU constantly at 90% or higher, projections at 5% fps drops to 40, this happens at Steam home, and the lab games, haven’t even opened Alyx, because I’m assuming the card will start to smoke. I am unbelievably disappointed in the 6800 performance in VR and already looking for a new card from Nvidia

  1. Thank you so much for providing VR reviews, such as this one. I managed to get a 6800XT by attempting to order one online as soon as sales began, but naturally that meant I could’nt know exactly what im buying 🙁
    VR Performance is important to me as I feel it takes the immersion to another level, so I naturally feel disappointed now, as it seems that 6800XT is poorly optimized for VR. Guess I will return or sell the card then, and try to get a NVIDIA card instead. Otherwise I was satisfied with the reference 6800XT, reasonable fan noise and coil whine, and my sample even undervolted to 980mV from 1150mV while slightly improving Heaven score at least. Again, big thanks for providing these tests to us! Its so difficult to find broad VR performance reviews and I appreciate that you guys make them!

    • The VR experience playing ACC is not at all bad with the 6800 XT. It is very close to the GeForce in unconstrained FPS and the framerate delivery is relatively smooth with the High VR preset. It’s actually better for VR than with the pancake game, and AMD may optimize drivers.

    • I dont see why you are disappointed, its right around where the money you paid for it said it would be. In fact, considering its a little cheaper than the 3080 its actually pretty great it took some wins. Other than Ark Park, AMDs card seems to offer at least what you paid for and in some cases better.

  2. Thank you so much for doing those tests and including ACC! This game is the main reason I was waiting for the new generation of GPUs, to feed my Reverb G1 Pro with. So a comparison between the 3080 and 6800 XT is extremely valuable! One thing I find odd is that the 3080 is 40% ahead of the 6800 XT on a 4k display while in VR they are within less then 10%. Do you think you could re-run the ACC test with a fair bit of supersampling? ACC is known to be extremely blurry at native resolution – so it would be very interesting to see if the 3080 can pull ahead again with higher resolutions or if both cards scale the same way. And if you could set up a grid of 40 or 50 AI opponents, that would very telling as well, since there are such different amounts of VRAM and the bandwidths differ so much. One final note: Please do your measurements after half a lap or so, because with ACC it is always the same story where it suffers a lot at the race start, but then snaps in momentarily after a few corners.

  3. Agreed that it is unusual to see 6800 XT lagging in the pancake game while doing relatively much better in the VR game.

    The problem is that I can’t push the resolution further at ACC VR high settings. It is already starting to synthesize some frames.

    What is happening on screen/in HMD most affects the video card’s frametime delivery as the AI is largely processed by the CPU. The race benchmark only has a relatively few seconds of the race start and you can see that instability on the frametime chart followed by a much longer and more stable plot. The benchmark is equally difficult for all cards that are tested.

    • Thank you for the reply! Of course AI itself is calculated by the CPU, but more cars means more objects filling up VRAM as well. Regarding resolution, I still think it’d be interesting to see how frametimes are with supersampling. As far as I’m understanding, ACC users are trying everything to get reasonable clarity, even if that means less eye candy and putting up with synthesised frames (or in case of the Reverb maybe with the 60 Hz mode). And if they can’t get the clarity in VR, they’re switching to a different sim or tripples altogether. Hardly anyone is accepting the default VR blur that’s typical for UE4 games and extremely detrimental in sim racing, because you’re constantly looking at distant objects here.

  4. Great work with these benchmarks again! BRT really is the number one hardware site for any VR gamer. Love that the test suite also includes so many of the hard to run VR games. Maybe Vanishing of Ethan Carter could be replaced by something else since it clearly isn’t a challenge for modern GPUs at this point?

    Something like MSFS2020 once available or DCS like suggested by Rage could make sense. My personal wish besides those would be Euro/American Truck Sim but those may be a bit too niche… Star Wars: Squadrons might be worth considering too as a recent AAA VR game and then there’s Medal of Honor incoming soon…

  5. Thank you for this testing in VR, all the other testing sites, like GamersNexus, HardwareUnboxed, Igors, seems to neglect the whole VR, while you are keep going.
    Now I only have to get me an 6800XT or an 3080, thats btw for the first time not based on test results, but on availability and an normal pricing. 🙂

    I have one suggestion for you, as there is one niche in gaming were VR (like in race sims) is not an niche any more and that is in fly sims. IL2-“Battle of Stalingrad series”, DCS and still to be released FS2020-VR, here you will find lots of VR users. It would be nice if these game are also be considered for an benchmark test.
    BTW since an Win10 reinstall I could not use FCAT-VR anymore, I’m using now fpsVR from STEAM thats now also have an logging system.

    • VR is my own area of interest and I am happy to see more interest that allows me to spend more time with it. Good luck getting a new card quickly at a reasonable price.

      BTR has added a second reviewer, Sean. He specializes in VR sims – racing and flight – and he is upgrading to a Reverb G2 and will also get a new top card when it becomes available. All of these sim games you mentioned are being considered for regular testing and benchmarking.

      It may be that you will need an older version of Anaconda 3 to work with FCAT VR. It’s good to see other VR benching systems like fpsVR.

    • There may be a small performance improvement with Zen3/SAM enabled. Unfortunately, 5950X is impossible for me to buy and compare with my OC’d 10900K.

      Yes, the is definitely hope that AMD will improve the VR experience and address any performance issues with newer drivers. This is the first driver set for big Navi.

  6. If we set 6800XT to 100%, how does 3080 perform?

    Assetto Corsa: 3080 = 110 %
    Ark Park: 3080 = 152 %
    Boneworks: 3080 = 91 %
    Elite Dangerous: 3080 = 104 %
    FallOut 4: 3080 = 95 %
    Alyx: 3080 = 109 %
    Hellblade: 3080 = 113 %
    Into the Radius: 3080 = 111 %
    No Man’s Sky: 3080 = 116 %
    Obduction: 3080 = 116 %
    Project Cars 2: 3080 = 96 %
    Skyrim VR: 3080 = 118 %
    Subnautica; 3080 = 92 %
    Ethan Carter: 3080 = 103 %
    Saints & Sinners: 3080 = 103 %

    Calculating the final average result, 3080 was 9% faster than 6800XT. The Ark Park may be a weird outlier, thus maybe better with median and associated quartiles, interestingly we get a similar result:

    Median = 109 (96 – 116)

    25th and 75th percentiles in the parenthesis, thus the middle 50 % of results range from 96 % to 116 %.

    • Thank-you and to everyone who supports VR and who reads our reviews! 4 years ago I did not expect to have such interest in VR so that I could lead off with a VR review of a brand new card. And the traffic almost crashed BTR’s server yesterday! Thank-you for your patience to those affected by those slowdowns. We are working with our host to address those issues also.

      It wonderful to see VR growing steadily and we look forward to devoting many more reviews to it.

  7. Please do extensive Oculus Link and VD test on both of them for Quest 2 and include encoding latency. Quality comparisons could also be included since supposedly on h264 AMD has horrible artifacts but on HVEC (Virtual Desktop) it’s pretty comparable.

  8. +1 DCS pls

    and OC results too!

    Ty and keep up the great work!
    I’m spreading your reviews in all flight sims forums i know! We need more in depth reviews like yours and less talk and marketing as proposed by other websites…

    Also with the new ryzens also a CPU test for VR is due… last one i saw is a tom hardware’s piece from 2018…

  9. Thank-you for your replies and suggestions. We don’t have Oculus/Quest 2 to test. Our next scheduled HMD upgrade is a Reverb G2.

    5950X is impossible to find in stock anywhere and not expected in quantity for sale until next year, so it may be awhile before BTR gets Zen 3. It also appears that Intel/Nvidia may get SAM, and an overclocked 10900K appears to keep up pretty well with Ryzen so we may even wait until the 5950XT refresh before upgrading.

    • They do not generally use the same settings. We have been fine-tuning settings for several of the past reviews to make them more representative of settings someone actually uses in their VR games with these new and more powerful video cards. It’s also in preparation for additional benchmarking using the Reverb G2 and the Vive Pro next year.

      Several of the games have remained with settings unchanged – you can cross-reference them with earlier reviews – but bear in mind that there have been game patches and driver updates between comparisons.

      BTR will do a “mega VR” review that benchmarks many cards competing in their own classes (hopefully!) next month. It will probably be structured similarly to the HL: Alyx review, but with 15 games.


      However, there are committed reviews in the queue ahead of it. The Red Devil RX 6800 XT will be fully reviewed and benchmarked against the reference RX 6800 XT and vs the RTX 3080, and also 2 new hardware reviews (one is VR!) due next week

  10. This article is perfect; the right games and the right graphs in a easy to read format. This is so much more informative than the usual min/avg/max benchmarks that everyone else is doing. Thanks for doing this, I hope it pays off for you guys!

  11. Another +1 for DCS please. There is a general assumption on the DCS forums that the 16gb VRAM of the 6800xt will be more beneficial than the 3080 due to the poorly optimised DCS engine. It would be great to put this one to bed.

    I personally have a 3080 sat in its box at the moment and am waiting to see if I can pick up a 6800xt this week as my Reverb G2 arrives next Tuesday. If I can pick up a 6800xt I will try them both and send back the one that loses. My only interest in these cards is for playing DCS in VR so not bothered about RT or pancake games.

  12. Hi, for my country the price of 6800 XT is 749eur and right now the MSI ventus 3080 is listed for around 799eur or even 779 in one shop around here. Naturally the waiting element is there too, but since I dont have a headset rn, im not in a rush. Planning to get a reverb G2. The 6800 XT seems incapable of synthetising frames in some games, and overall it has more frame drops as well, which should mean more stuttering as far as I know, and with the experience I have from CV1, I will notice them. Also the average unconstraided fps is below the 3080 a little, and for me these are totally enough to justify 6,6% higher cost, knowing I likely would have the more stable option for VR. Im not an expert in VR, an intermediate user at most I would say, so of course I dont know everything. This is however my conclusion from this review, I appreciate your reply, hope you have a nice day!

  13. So heres one for you guys, I run a Pimax 8kx which is a 4k panel and wide FOV on a 2080TI I recently got a 6800XT. Both cards were OC’d on blowers.

    The 6800xt in most cases failed to match the 2080TI in VR performance and in a few cases beat it by 5-10FPS on the same settings. Im assuming this has to do with its trouble dealing with 4k content this may apply to the Reverb G2 but maybe to a lesser extent because of minimal FOV.

    I was running the same settings as you in the control panels, So much to say I had to get rid of the card as much as I wanted to like it. AMD still has some way to go on the bleeding edge. Judging by this performance I wouldnt expect the 6900xt to do significantly better.

    Could be a driver issues who knows its a new card but that performance loss of 10-20% i saw at times was alarming vs a 2 yr old card.

    Taking into account the gap has tech wise on AMD with DLSS 2.1 etc I wouldn’t recommend this card for the top end VR

  14. Awesome comparison of this two GPUs in VR!! Thank you so much.
    Some of the games (Boneswork, Fallout, Project cars 2) and syntetic benchmark (FireStrike) uses DX11 and it seems that the Red card is better. But in other games you can opt for DX or vulkan.
    It would be interesting if you add to the comparison what is the API used in every game or benchmark.
    It would be nice if you could add to the list another DX11 flight sim: IL-2 BOS
    There is a benchmark mission of 1 minute that it can be used for comparisons:

  15. how can you possibly compare cards? one is 16GB the other 10GB? The 3090 was the choice for benchmarking… but that would have absolutely embarrassed AMD.

    What a joke. Cant believe people supporting this review lol..not even fair and nvidia still wins lol

  16. Seems like the 3080 is on top most of the time. For VR stick with Nvidia. Maybe AMD will improve performance through driver updates. RDNA2 has Variable Rate Shading. Ball is in dev’s court now, to support it.

    Honestly didn’t look that bad for AMD.
    I mean, they are behind, but it looks like a viable alternative and still somewhat trading blows (or getting close).
