Splinter Cell Chaos Theory Purple Textures

[mehmetmunur]

I was playing the demo for Chaos Theory the other day and noticed purple textures on some wires, on a bridge and a whole room was rendered red instead of dark brownish. Has anyone else had any of these problems, or should I be worried about hardware problems.
