From my experience with Dolphin:Ashen said:What version of windows you are running has nothing to do with performance. The main GFX plugin for dolphin is coded for directx 9c. Which is compatible all the way back to at least windows 2000 or earlier. If you're getting crap performance its probably because: 1. you have some settings screwy 2. Your PC just cant handle it. My subpar XP machine runs dolphin just fine at min graphical settings.
