Just tried the demo and after turning down depth of field in the graphics options, the black areas disappeared. Nothing else was changed after installation.

I can launch and play the game (with some flickering and whatnot) with proton 3.7-8 (and 3.7-8 beta); but with proton 3.16-3 beta, it hangs at the loading screen just after the intro videos.

I had a weird problem reproducing the problem this morning. My best guess is that the game was still using proton 3.7-8 beta even though 3.16-3 beta showed as the version in use in my Steam Play settings - probably just a UI hiccup? I certainly don't remember switching back to 3.16-3 beta last night. It was a surprise that it was selected this morning.

Anyway, I switched to 3.7-8, then switched back to the 3.16 beta (which is now 3.16-4 beta) - and the issue is back.

I let it run for ~30 seconds before killing it (side note: it ignores kill -15 and I have to use kill -9). Let me know if more or less time would be helpful.

This game works flawlessly with Proton 3.7-8 on my system but it seems it's borked on Proton 4.2. I did not test with 3.16. Looking at protondb, there are two reports with similar setup I have, that have the same issue: game crashes to loading screen when starting new game. Log of the crash with 4.2-9 here.

i had those glitches too, after some fiddling around with proton versions, i deleted the prefix (i lost my savegame, be prepared) and started with proton 3.16-9 and the following launch option: PROTON_USE_WINED3D=1 %command%
now it works without any problems. i played around 2 hours at once now.

It runs for me with 4.11-9, but there are some rendering artifacts now (green and/or opaque god rays), some missing effects (no tail when he lashes out at enemies) and it seems like the Depth of Field (DoF) "high" setting is no different from medium (the only other setting apart from "off").

D9VK works better: there is a tail when slashing, and the god rays at the start aren't green/opaque. But DoF set to high doesn't look any different from medium. The effect is clearly different on Windows though.

Symptoms

Game runs, but crashes when changing resolutions. Upon launching the game again, resolution change is not saved.

@kisak-valve
Using "PROTON_USE_WINED3D=1" does fix the issue.

It is an internal problem of Wine or for a specific patch, I have that problem when I change the resolution with all versions of PROTON (Proton 5.13 or Experimental) but with Proton GE 6.1 it does not happen, it changes resolution without any problem.
