Dying Light: The Beast Low Framerate when FSR is Enabled
the framerate drops significantly
what does that mean exactly, can you be more precise? Most likely this is just explained by FSR4 i8 being used instead of FSR3?
I tried to capture the framerate in just the main menu with the two initial screenshots (164 FPS with TAAU, 54 FPS with FSR 4.1.1).
Here's another scenario in game
DX12 with TAAU, 164 FPS
DX12 with FSR 4, 3, or 2 enabled, 25 FPS. The game runs consistently around that framerate.
DX11 with FSR Quality, 116 FPS
Thank you
ok, that's a very large drop. Hopefully someone can reproduce it.
Another thing you can do is to add MESA_VK_TRACE=rgp MESA_VK_TRACE_TRIGGER=/tmp/trigger %command%, then while in game with the ~20 fps, run in a terminal:
$ sleep 3 && touch /tmp/trigger
then wait for a while in the game until a capture is made, then upload the .rgp file /tmp. Make sure to remove the MESA_VK_TRACE=rgp stuff from launch options afterwards since it will impact performance of non-debug runs.
nvm the suggestion above, apparently the game is doing something broken and creating a bajillion DXGI factories which would explain it.
Should be fixed by https://github.com/doitsujin/dxvk/pull/5782

When DX12 is enabled in game and FSR is turned on (2, 3, or 4), the framerate drops significantly. This didn't happen in previous versions of proton experimental, I think it started when the new FSR 4 DLLs got included. Turning off FSR or switching to DX11 and keeping FSR enabled restores normal performance.
