i updated video drivers, DirectX even i installed Windows 8.1 Prevew ,installed steam, downloaded Gmod but it didn’t fix it

i’m using an nVidia GTX 550 Ti with GeForce 320.49 driver

sorry for my bad english :slight_smile:

…uh any description of what “this” is? What happened? blank screen? Flickering? Artifacts?

well flickering… the physics gun and the trees are flickering random, no black screen, some of the textures are in a werid look and some of the text didn’t show (only in the main menu, the tools menu and the console the text show). i dont have any of this problems on Portal 2 or Half Life 2
