I turn to you for a problem between Clear sky and Vista. This one does that directx9 launches. If I try the lighting directx10, and I relaunch the game, I rest on a black screen with the cursor vista that appears.
In the log file, the error is fatal as follows:
Too many lmap-textures (limit: 8 textures or 32M).
Reduce pixel density (worse) or use more vertex lighting (better)
I tried to reinstall my drivers, DirectX, the game itself, such, even if I couacs goes DX10. My config: E8400 a 3.8, 3870x2, 4 GB of RAM and vista 32.
