BF3 scales pretty well. I've seen it on Medium and everywhere above. To be honest y you have to look really hard to notice the detail. I mean it is noticeable, but when you are running around with crap blowing up all over the place and bodies flying, you aren't really going to care much. I would be most concerned with running it at a stable 60FPS so everything is smooth. Just turn on Vsync, set video settings to AUTO, and go gettem.
