I'm on an AMD system, but adding "VKD3D_CONFIG=no_upload_hvv" to my launch options fixed all the weird stuttering and significant performance issues for me. It disables reBAR while the game is running, which I wouldn't think would do much, but boy was I surprised when it solved the issues! I've also seen some reports on protondb that running the game through game scope might solve your issues on Nvidia hardware.

"Collapsing" by Demon Hunter slaps. Thank you, Killing Floor 2, for introducing me.
This might be due to windows hibernation behavior. When you shut down windows 10 and 11, it actually hibernates the drive instead of a full shutdown. You can disable it by turning off "fast startup" option(s). I haven't had to do it in a while so I can't recall exactly where the option lives. Hibernated drives get marked to prevent writing to them as it may corrupt the windows install.
