Okay, so one day while playing America's Army, I start getting weird colors in random places. But it's not artifacting. It's like a lighting problem. I'm not sure why. So I uninstall my video drivers, reinstall them, and AA works perfectly again, for about a week. Up until this morning, when it started again, but seemingly worse.
I really don't get it... I've tried all kinds of settings, but none get rid of it. Anyone ever seen this before?
And it only happens on America's Army. Far Cry, Half Life 2, GTA:SA all work fine.
