Trying to troubleshoot lower than expected FPS (aussie.zone)

Getting around 130fps avg frames, sometime dipping down into the 80's, when playing CS2. Did a recent system upgrade and presumed performance would be better than this for the build?

Gear:

  • Ryzen 7 5700x 3.4ghz
  • 6750XT 12gb ddr6
  • 16gb 3600mhz ddr4
  • m.2 SSD
  • 144hz , 1440 screen with freesync
  • Running Mint latest version

Have tried in-game settings at lowest, still not managing to get a stable FPS above 144. Mucking with settings doesn't seem to change performance much. Have set game to run with '-vulkan' which helped reduce some stuttering issues, but not much performance gain.

I also only get <100fps with other games like BG3. Figured this kit would be able to handle modern games a bit better. Any ideas what's going on?

EDIT: For future reference, the following changes were made and am now getting ~200fps

  • Enabled asus EZ Tune in BIOS (rather than manually muck with each setting)
  • Updated gpu drivers via 'amdgpu -install'
  • Enable gamemode

There are some bugs with recent kernels and 6XXX cards. Try kernel 6.5.X and also look at the workarounds here: https://gitlab.freedesktop.org/drm/amd/-/issues/1500

In addition, make sure "Above 4G decoding" is enabled in BIOS/UEFI so you get resize rebar support.

Beyond that, make sure you're using mesa (and not amdvlk) and that's it a version from this year at least (23.X.X)

Resize Rebar was something that was previously switched off I discovered. Turning this on via the Asus EZ Tuner made a great difference. Found im still on a Mesa 22.x driver for some reason, despite running latest driver update, and my kernal is showing 5.15.x, despite having all OS updates installed.. will need to investigate, perhaps a Mint issue. Thanks!

5.15.X is the previous LTS kernel. Probably the default when you installed it. I don't use Mint but you should be able to use 6.1.X at the least (the current LTS kernel).
