Hi. There are several bugs affecting only the MT version on DX9. These issues are not present in the regular version, and I haven’t noticed them in MT DX11 either.
1. On DX9, there are issues with shadows on hands - both from artificial lighting(flashlight, glow stick) and sunlight. The shadows look broken, and noticeable jagged artifacts appear when rotating the camera.
2. The game hard-freezes when switching the renderer (R2a, R2, R2.5). It also completely freezes when changing some graphics settings that normally require a restart.
3. In fullscreen mode, the game freezes when minimizing.
Here are examples of shadow issues:

upd. Logs when minimizing the game(screen resolution is 1680×1050):

P.S. The issue on older systems (SetThreadDescription), including Windows 10 LTSB, has been resolved(v2026.4,21). Thanks.
