GAH!! Somebody else has to have this problem...Ok, I still play quake tf (quakeworld). Anyway, i just installed windows xp prof. Everything is fine EXCEPT when i play tf the mouse does some weird things....I've been told it's some mouse acceleration thing with Win XP. I have no idea how to turn it off. In Counter Strike...there is a command that guys put into the command line that gets rid of the problem...well i dont' know of such a command for quake. Is there someway to fix this...it is so annoying and has totally destroyed my aim...ANY HELP IS APPRECIATED...THANKS!
