Re: SV: [pygame] Fullscreen perfomance problems

Your driver are too old ?

http://www.pygame.org/docs/tut/newbieguide.html
   It might be slower anyway. Many drivers are not accelerated for the 
types of drawing that we do, and since everything has to be blitted 
across the video bus (unless you can cram your source surface into video 
memory as well), it might end up being slower than software access anyway.
