Adrenalin 21.9.1 Driver Performance Analysis – 24 games benchmarked using the RX 6700 XT

This review showcases Radeon Adrenalin driver performance of the reference AMD Radeon RX 6700 XT (RDNA 2.0) with 24 PC games. We use the latest AMD Optional (beta) Adrenalin 21.9.1 driver released a few days ago and compare these drivers versus our previously recommended driver 21.8.2. We also chart the performance of the 21.6.1 (WHQL) drivers as a reference, and we perform all tests on the same game version and with the same OS build.

For our Adrenalin driver reviews, we use ‘beta’ instead of ‘Optional’ and ‘WHQL’ instead of ‘Recommended’. We don’t use AMD’s Recommended label since we recommend drivers.

Our AMD Radeon RX 6700 XT (Reference, RDNA 2.0 GPU micro-architecture).

Our testing platform is a recent install of Windows 10 64-bit Pro Edition, an i9-9900K with stock clocks, a Gigabyte Z390 AORUS PRO motherboard, and 32GB of T-FORCE XTREEM ARGB WHITE DDR4 3200MHz. The games tested, settings and hardware, are identical except for the drivers we compare.

Radeon Software Adrenalin Suite-related

  • The minimal Radeon Adrenalin Software installation is used.
  • We install the display driver.
  • We enable the ‘Issue detection’ setting.

Hybrid & Non-Synthetic Tests-related

  • Single run per test.

Game Benchmarks-related

  • We use the corresponding built-in or custom benchmark sequence.

Frametimes Capture & Analysis tool-related

  • CapFrameX is used for capturing and analyzing the relevant performance numbers obtained from each recorded built-in or custom benchmark sequence.
  • Consecutive runs until detecting 3 valid runs (no outliers) that can be aggregated by CapFrameX using the following method:
    • ‘Aggregate excluding outliers’:
      • Outlier metric: Third, P0.2 (0.2% FPS percentile).
      • Outlier percentage: 3% (the % the FPS of an entry can differ from the median of all entries before counting as an outlier).
  • We compare and value the results and aggregated records in terms of percentages of gain/loss, by setting the following thresholds to consider a certain % value as significant (not within the margin of error) for our benchmarking purposes:
    • Score/FPS Avg > 3% when valuing hybrid and non-synthetic benchmarks;
    • FPS Avg > 3% when evaluating raw performance;
    • P1/P0.2 > 3% when evaluating frame time consistency; after applying our custom formula

{[(LowPercentileFPS_2 / AvgFPS_2) / (LowPercentileFPS_1 / AvgFPS_1)] – 1} x 100

        • While playing Assassin’s Creed Odyssey, driver timeouts or black screens may be experienced on some AMD Graphics products such as Radeon RX 480 Graphics when the user quickly navigates through the game menus or swiftly looks around an environment with their character.

The Adrenalin 21.9.1 Driver Performance – Summary Charts with 24 Games

Below you can find the summary charts of our representative selection of 24 games plus 4 hybrid and 4 non-synthetic benchmarks. We chart our games’ driver performance progression from version 21.8.2 to 21.9.1 using the reference AMD Radeon RX 6700 XT.

You can see the list of graphics settings on the charts, and we run each built-in or custom game benchmark’s sequence at 2560×1440, except for Days Gone and Far Cry New Dawn, tested at 3840×2160 resolution; and LEGO® Builder’s Journey (DX12 & DXR) and Watch Dogs: Legion (DXR) which are tested at 1920×1080 resolution. You may click on each chart to open a pop-up for the best viewing.

Results give average framerates and higher is better. We display the low FPS percentiles (P1 and P0.2) below the corresponding averages. We use CapFrameX to record frametimes over time and to visualize and convert them into their corresponding average FPS and P1 and P0.2 FPS percentiles values.

There are also columns showing percentages of gain/loss in both raw performance (average FPS) and, when applicable, in frametimes consistency or stability between the different driver versions. We applied the following custom formula to calculate the stability gains or losses:

{[(LowPercentileFPS_2 / AvgFPS_2) / (LowPercentileFPS_1 / AvgFPS_1)] – 1} x 100

We mark significant performance changes (higher than 3%) in bold and use purple for the significant improvements or orange font for regressions.

Notes on Adrenalin 21.9.1 Driver Performance – 21.9.1 (beta) vs. 21.8.2 (beta)

From the charts, although most hybrid and non-synthetic tests show no significant differences between drivers using our RX 6700 XT, we see a noteworthy improvement in the DirectX Raytracing feature test and a regression in the Basemark GPU (Vulkan) test.

For the game benchmarks, although most games show no significant differences when we move to the 21.9.1 beta drivers from the 21.8.2 beta driver version, we found significant performance improvements in DIRT 5 (DX12 and DXR API modes) and in Myst (2021, DXR API mode) in terms of raw performance.

Please be aware that the following results, notes, and the corresponding driver recommendation are valid for similar RDNA 2.0 gaming rigs on Windows 10 v21H1. Its representativeness, applicability, and usefulness on different AMD Radeon micro-architectures, testing benches, and Microsoft Windows versions may vary.


Based on our previous results and findings, we recommend RDNA 2.0 gamers update to the latest Adrenalin 21.9.1 beta driver. Its raw performance and smoothness or frametimes consistency level are overall on par with our previously recommended driver 21.8.2 using our RX 6700 XT GPU.

There are relevant qualitative reasons that also make it advisable to upgrade to version 21.9.1. These reasons include the higher level of driver bug fixes, the optimizations for the latest games, and support for the latest AMD Radeon technologies.
