I run GameEx in vertical mode on my EGRET II. But I don't have a dedicated computer for GameEx (I will, but that's in the repair shop) yet, so I don't run Windows rotated, I just let GameEx rotate. And I don't run it in 480p, but in 480i, so I don't get any warnings. What is your video chip, AVI, nVidia or other? I'm running Omega drivers on an ATI 9700 onboard chip (Laptop) for your reference. Unless you use your computer for other stuff than GameEx, I see no reason to run Windows in tate mode. Emph
