Yeah, I tried DX8 and DX9, same thing

I finally got it working after tweaking a bunch of settings. Turns out, the key was to install the K-Lite codec pack and turn off compatibility mode for older versions of Windows. After trying different options, everything is running smoothly now.

Settings:
- Device: HAL

Texture Quality
- Standard

Texture Filtering
- Anisotropic

Mipmapping
- Off

Frame Limiter
- 60 FPS

Vertical Synchronization
- Off

Render Target
- On

Render options
- High-Res Fonts: On
- High-Res Assets: On
- Boost Font Size: On
- Hardware Vertex Shading: On
- Windowed Mode: On

Shadows
- Max

Launch only via configuration tool

I managed to get it to run directly from Steam without configuration tool, I had to install LAV Filters directly on top of K-Lite codec pack, this let the intro video finally play (black screen in TiTS FC is usually because of video decoding not working and config just lets you skip the intro). Go to github.com/nevcairiel/lavfilters/releases and install that, helped me to get it to run on both Windows 10 and 11.
