Test Configuration – Software

  • NVIDIA’s GeForce 411.63 WHQL drivers used for overclocking both cards.  399.24 is used for the GTX 1080 Ti stock clock results and launch drivers 411.51 were used for the RTX 2080.  The drivers used are functionally identical in gaming performance except for specific bug fixes.  See Control Panel image below.
  • VSync is forced off.
  • AA enabled as noted in games; all in-game settings are specified with 16xAF always applied
  • Gaming results show average frame rates in bold including minimum frame rates shown on the chart next to the averages in a smaller italics font.  Some OCAT captured minimums are given in frame times and expressed in ms
  • Highest quality sound (stereo) used in all games.
  • Windows 10 64-bit Home edition. All DX11 titles were run under DX11 render paths.  DX12 titles are generally run under the DX12 render path unless performance is worse than with DX11.  Three games use the Vulkan API.
  • Latest DirectX
  • All 36 games are patched to their latest versions at time of publication.
  • MSI’s Afterburner 4.5.0, used to adjust the GTX 1080 Ti and to set temp and power limits to maximum.
  • Precision X1 0.2.6 public beta version for RTX 2080 settings and for overclocking
  • OCAT, latest version
  • Fraps, latest version

NVIDIA Control Panel settings:

Here are the NVIDIA Control Panel settings.

We used MSI’s Afterburner for the GTX 1080 Ti to set its power and temperature limits to maximum since Precision X1 is not yet set up for Pascal.  We used Precision X1’s automatic scan as well as its manual settings to overclock the RTX 2080.

By setting the Power Limits and Temperature limits to maximum for each card, they do not throttle, but they can each reach and maintain their individual maximum clocks.  This is particularly beneficial for high-power cards like the GTX 1080 Ti and the RTX 2080

Let’s check out overclocking next.
