--- Comment #3 from Sveinar Søpler cybermax@dexter.no --- Thanks Józef Kucia. That hack did absolutely help for the "Medium" texture preset, as it seems "fixed" from a brief glance.
High and Extreme did however have some weird discoloration/lighting on the gray wall by the door for some reason. That might not mean too much, cos i was able to crash wine a couple of times loading the "extreme" preset with dxvk too.
Will do some more testing.
