Breakstuff I CANT run G3 w/everything on highest setting w/my $400 video card it turns into a slide show. I can run all the latest DirectX9 games on my PC and I get great performance w/settings maxxed, G3 is the only game I've got that cant be run at max settings. Try running Battlefield2 w/ all setting maxxed w/your Radeon and watch what happens
edit: why would you want to lower all your settings anyway?
Theirs a guy who posts here called "r1derbike" who has a dual 6800ultra setup that can run G3 at max settings (thats like $1200 dollars worth of video cards)
