Game working, but graphics screwed up

[lmkcrown]

I'm getting smal patches of missing textures and lines running all over the screen(see screenshot). The amount and size of the lines can be as little as in the SS to a lot more and thicker so it covers most of the map. I've had a simular problem with Counterstrike:Source, but not as much. UFO: Aftershock doesnt have it at all. I've tried putting the shaders to 1.1 but no change, dont know what else to do.
