steam-950670.log.gz

I confirm:

• that I haven't found an existing compatibility report for this game.
• that I have checked whether there are updates for my system available.

Symptoms

The geometry of the game is flickering all over the place. It seems like some vertices have wrong coordinates.

Reproduction

Just start the game with DXVK enabled. It is already visible in the main menu.

Workaround

Don't use DXVK. Run the game with PROTON_USE_WINED3D11=1 %command%.

Start by reviewing steam-950670.log.gz and reproducing the flickering in Gothic Playable Teaser with DXVK enabled. Compare it with the PROTON_USE_WINED3D11=1 workaround; done means identifying and resolving the DXVK rendering issue without requiring that workaround.
