Hello @magos-linux, if it's not too much hassle, it may be worth retesting with Proton 3.16-4 and nvidia 396.54.09.
Hello! I had the same results on Proton 3.16-4 right now
Also there are some other reports on https://www.protondb.com/app/635200
It is not necessary to switch to DX9 mode if using drivers with transform feedback support and the latest Proton beta.
