Hi,
I'm getting significant CPU bottlenecking when I play games with vkd3d. From time-to-time my FPS gets halved in Horizon: Zero Dawn and in Death Stranding it happens every time I drive. On windows I get 100+ FPS for both but on linux it can go below 50 easily and every time it happens I see MangoHUD showing my GPU being underutilized. This doesn't happen on windows.

My PC->
CPU: Ryzen 5900X(IF: 1900, cooler at max performance).
RAM: G.SKILL 3800MHZ CL14
GPU: RTX 2080
Storage: NVMe SSD
Driver version: 465.24.02

This is already fixed in current development builds. Also no CPU bottleneck but rather asynchronous compute not being asynchronous.

Wow, that's great! How can I use those?

Nvm, I patched a proton prefix with the dlls. Now the GPU utilization is almost always above 90% but for some reason it drops from 99% to 95% every second. I used the 6.5-GE-2 pfx.

Nothing extracted yet.
