Anytime I play on a map that has some sort of powerlines, they show up as a white wireframe. It happens when I play Gmod on tf2 maps, as well as HL2 maps, but not in the other games themselves.
I’ve verified the game files of garrys mod, hl2, and tf2, and it is still there.
I’m running Windows 7 64bit premium
an Nvidia 9800gt
6gb of ram
AMD Phenom X4 9850 Black Edition.
