Black Textures L4D2

[Blackylol]

Why is this happening? black textures and look the flash light.

I can run this game perfectly on windows, no problem with the textures or lights i'm using mat_hdr_level 0 just to improve the perfomance in linux, it doesnt affect the textures, on or off is the same.... i also tried to change the video settings on game from low to high and same result.

but anyway my system specs

Pentium 4 3.0 ht
Nvidia 6600 gt 256vram
1gb ram
Ubuntu 10.04
wine 1.2 rc2





Thanks
