As you can see from the attached screenshot, Gothic 3 is rendered all black and with very poor performance. If I followed D9VK development correctly, this should be already been fixed, but not on my end.

I tried various launch options, different graphic detail, but nothing changed: I got always the same result.

Game renders correctly using WineD3D, but is even more slow and unplayable.

Can you try 1.5.2? Also, are you using native d3dcompiler and d3dx9 dlls?

The game is known to work with DXVK, see #1367.

@ziabice I ran the game using winetricks d3dx9 if this helps you out.
But also used Lutris rather than Proton and therefore vanilla Wine.

Edit: Also the CPT 1.75 introduces very bad performance, at least for me, from 130 to 20fps I suggest using 1.74 as the latest CPT in order to have a pleasant time playing the game.

Ok, mystery solved, for some reason your exe name is different than everyone else's (Gothic3Final.exe vs Gothic3.exe) so the workarounds to make this broken mess of a game run don't apply.

You can fix this for the time being by putting the following things into dxvk.conf:

d3d9.allowLockFlagReadonly = False
d3d9.supportDFFormats = False

Thanks to your help it works now.

Here's what I did:

created the dxvk.conf in my home directory adding the settings you said:

d3d9.allowLockFlagReadonly = False
d3d9.supportDFFormats = False

(please note: no [gothic3.exe] or [Gothic3.exe] before the options because it didn't work)

Used this launch options in Steam: PROTON_FORCE_LARGE_ADDRESS_AWARE=1 PROTON_USE_D9VK=1 PROTON_LOG=1 DXVK_HUD=full DXVK_CONFIG_FILE=/home/luca/dxvk.conf %command%

And the game worked as expected. Like crap, but it worked. I have nearly no GPU utilization and FPS varying from 10 to 40.

I can see shadows even with DXVK 1.5.1 supplied with Proton 4.11-12, despite what stated in #1367.

The game exe is Gothic3Final.exe in your case, not Gothic3.exe. This is the same reason why the default workarounds didn't apply.

I can see shadows even with DXVK 1.5.1

That's because you set d3d9.supportDFFormats = False. Remove that line and you'll get broken shadows - the fix in 1.5.2 was to also set this option by default.

You are absolutely correct! :+1:

Just for the record, into the game dir there are two executables: Gothic3.exe and Gothic3Final.exe.

Thanks very much for the clarifications! :heart:
