Games seem more responsive with AA on?
Ever since I installed Windows 7 most of my games have played with microstutter and very noticeable mouse lag. That is until I forced AA on in the separate games listing page. Take UT3 for example, I couldn't figure out how to get rid of the annoying mouse lag that I felt, no matter the resolution or the settings I used until last night when I forced 16xQ CSAA, I lost maybe 20 fps from the 150 - 180 I was getting but now the mouse has no lag at all and it's like night and day.
Mass Effect 2 seems to also work much better now that I have 2x AA enabled.
