Hi!
When I compile my games for windows and run them in fullscreen, all
blits are displayed immediately. Why don’t they wait for
SDL_UpdateRect(s)?
Thanks, Karl.

Heheh, most people have the opposite problem - they want immediate updates
and they can’t get them. Just don’t ask for SDL_HWSURFACE, which if you
get it, is direct access to (slow) video memory.
See ya,

errr. I’m lost Sam. Slow video memory? I thoguht we wanted hardware
surfaces if we could get them, and as long as we don’t manipulate the
surfaces directly they’re way fast for blitting and much better that using
update_rects() with software surfaces.
Right. I meant slow for direct pixel access. 
See ya!

Wouldn’t SDL_HWSURFACE | SDL_DOUBLEBUF work better/faster?–
