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.
