I am experiencing severe rendering/shadow artifacts in Black Mesa after manually updating the game's included DXVK to the latest release.

When I replace the d3d9.dll in Black Mesa's dxvk folder with the 32-bit d3d9.dll from DXVK version 3.0, large solid black shadows or texture spots appear on walls, floors, and objects (like trash cans). These black patches shift as the camera moves.

This issue does not occur if I use the older version of DXVK that is built into the game's files by the developers. I have attached a video demonstrating the exact visual glitches.

(Note: Please see the attached video file below showing the solid black artifacts in motion)

Try with current master. There have been a few regression fixes since the release https://github.com/doitsujin/dxvk/actions/runs/28619281406
