Batman: Arkham City - GOTY (200260)
Note: to access the settings, must select "configure PC options" on launch instead of jumping straight into the game
Regression: When the configuration is set with DirectX11 Features and DirectX 11 Tessellation on, the game will fail shortly after launching, before getting into a game with an error dialogue "Rendering thread exception: Fatal error!....." (screenshot of full error attached).
This is a regression from dxvk-1.3.4. I tested this with Proton 4.11-6 which includes dxvk-1.4 and got the failure. When I dropped in dxvk-1.3.4 I did not get the error with the same settings and the game was playable.
The game failed to launch straight from the exe. I tried both BatmanAC.exe and BmLauncher.exe but they failed before getting to the bug, so I don't have an apitrace to upload.
