Please make an apitrace. There's a guide for how to do that in the wiki.

Hi follow the file.
RRRE64.1.zip

That file is basically empty. You need to upload the other one.

Have you verified you aren't hitting a memory or vram limit system wide? The fps seems quite low to me even with native d3d9.

I'm having problems, when I use the d3d9.dll files from apitrace-11.1-win64 the game is crashing.
But when I use d3d9.dll from dxvk-2.3, the game opens but the trace remains the same as what I posted previously.
I managed to take a trace using D3D9 instead of VULKAN, see attached.

Can't reproduce on GTX 1660 Ti (545.29.02). Runs around 120fps with AI, which is kinda expected from my CPU (i5 9300H) + Wayland.
VRAM usage on High settings is around 2GB.

@lucastva Give this a try again with latest dxvk master if you can

Same thing...
Version: DXVK 2.4.1
About 47 - 65 fps

On last updade RaceRoom on DX9 running about 68 - 75 (my refresh rate monitor is 75)

@lucastva Does it help if you make a file called dxvk.conf next to the exe and insert d3d9.cachedDynamicBuffers = True ?

@lucastva Can you give this a retest with dxvk 3.0?
