do not know if you fixed your problem however I would suggest reinstalling Q3. It looks like tuneup changed or possibly got rid of something Q3 needs. (of course, there are many other things that could have happened.) I do not believe it has anything to do with the graphic drivers or a openGL extension because you would usually get an error in the q3 console. Is there by any chance a ram 'optimization' in tuneup?

I do not use 'optimization' programs. When i was a kid and believed in fairy tails, yeah, but even then i didn't expect my P1 to run like a p350239850329520 from the year 5 billion AD. That was when I was 10 of course.

I'd rather suggest Hijackthis, spybot search and destroy, CCleaner, Defraggler and a good look in your services disabling what you do not need however, that is really minuscule. Yes, there are pirated performance editions of XP floating around out there which work quite well.

hey dude , maybe but only maybe, i remembered what the fucking prob was, ( it was not tune up ) do you have windows xp and after that service pack 3 installed ? service pack 3 can be responsible for that games or progs dont run well , too. so if you have service pack 3 installed, try to kick that bitch out of you system, think that was the error bc of that i got same message like you.

hm , its real hard to help you without seeing or knowing what you all have done, maybe best thing is that you reinstall windows one last time again and than do none of the things that maybe did the error, so no tune up no new graphic driver etc .
