is there anyway to quickly access video memory? i want to be able to process every pixel on the back buffer, the only way i can get this to work even remotely fast enough is to copy it to system memory surface first then blt it back. is there a better, faster way?

Hi

With DirectDraw, no Problem, only lock the Surface, then you retrieve a pointer to MemoryBLock, and there you can do what you wan''t
