I got it working using the steam version via proton 5.0 but it's experiencing the same sprite glitch as the one running just wine.
it's being very tempermental right now for some reason, doesn't like being logged ? whatever.
the only thing that pops up before it started acting even more buggy is apparently wine was built without vulkan support,
something about there not being NTLM support , idk what NTLM is.
it complains that it can't find a ntlm_auth.
then it complains about OpenVR , didn't know this game would have VR XD.
it looks like my best bet right now would be to rebuild wine with vulkan support because i already have the dxvk installed for it
then i can try to figure out what this ntlm thing is.
it was using the open source nouveau drivers for the graphics card which appears to be the issue, i only tried this because i began noticing issues in other games.
i had the proprietary drivers installed but they were not being used at the time because the kernel was loading it's own internal driver.
