Those are what you call "artifacts", check your GPU temp when you play crysis.
arifacts? I thought those were strange random lines and overlapping of some textures.
Mine are like red dots filling specific portions of the objects, mostly the shiny parts, such as the bald head,chin,boot tip, etc of the soldiers. In split second, I observe them on my car's rims, rear parts, glass, bridge, etc. I don't think they can be called artifacts exactly.
