Im having similar problems is Quake3, RA3 or the whole QUAKE3 Engine.
When I start the programs its seems fine, but when I move around the menus, it just freezes and the sound repeats. It then comes good for a sec and does it again. I cant play Q3 anymore because of this.
First I thought it maybe my Radeon 9700 Pro, but it could be Direct X 9.
So please while you quake freaks are out there, please help Wiseman and myself, play Quake 3 in any mod etc.
I hope it is just something simple. Also I have updated to PR1.32. But that didnt help.
