I have recently gotten my ROG 750J. I have installed all new drivers, audio, graphics, etc. I seem to have issues in games including a really low graphically tasking game such as the new borderlands. Some textures will be extremely blurry, or misplaced and i also keep getting these lines that go from the bottom of the screen to the top every few seconds or so. These problems also exist in the new COD, Anarchy Online isn't even playable (rendering issues), and Left4dead, and (pretty much any game). Anyone have any idea what is going on?
