Regression: Batman Arkham City GOTY fails with dxvk-1.4 with DirectX Features and Tesselation on

Software information

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.

System information

• GPU:AMD Radeon RX 470
• Driver:amdgpu
• Wine version: Proton 4.11-6 (based on wine 4.11)
• DXVK version: 1.4
  Note: originally reported here with NVIDIA gpu: Batman: Arkham City GOTY (200260) ValveSoftware/Proton#309 (comment)

Apitrace file(s)

• 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.
