im just saying if all you had to offer the guy was a mouse change, then thats pretty funny. and if the sarcasticness is the funniest thing you've heard, then you need to get out more.
no, gameguru and a few others already gave him the "usual" good advice in helping him out. i'm stating a fact.....for me, new mouse worked, period.
just telling him to try that, what's the big deal with that advice?
maybe your vid-cards a bit outdated, but like ICS said, update the latest patch....and if all else fails, uninstall and re-install the game.
