I just bought the game Oblivion last week and have been enjoying it, but frame rates are low because of the high system requirements on both the CPU and Video Card. Forum after forum have tweaks on how to turn off Windows XP features so that frame rates will be a bit better, and this is even for cards, like ATI's X1900XTX, and nVidia's 7800GTX.

I'm worried that an OS that needs all the horse power that Vista is asking for will leave very little for games like Oblivion.
