Hi.
I am using Windows XP and setting SDL_VIDEODRIVER solves the framerate
problem, but the mouse cursor is strange. If I remove the flags
pygame.DOUBLEBUF and pygame.HWSURFACE of the display.set_mode function the
mouse cursor is a little better.
What may be the problem?
Thanks for your help.
Pedro.
