Hellow, Got my iMac two days ago (first mac for me). LOVING IT!! Doom 3 runs great in OS X, but I cannot get rid of the annoying screen tearing..? As thread title suggests, I have of course enabled V-Sync. But the tearing STILL occurs..? Is there a solution to this? Some settings I have not spotted? Oh, side question.. And is there a way to "hack" some settings to be able to choose 1920x1200 in resolution? I can choose max 1600x1200..
