Well, in my even more humble opinion:) Even newer computers videomemory is rather much slower than the processor(even if their memory exceeds the computer memory in speed), ex: on my amd300 a loop wich moves bytes or an inline rep stosl that transfers information from memory to videomemory is equally fast. And, on older gr-cards bank modes might be faster because it's hardware implemented(and no software workarounds) and the other way around, fornewer cards. Thats the most important, not a houndred clockcycles to switch bank. I'm always trying to move as little data as possible, ram->ram and worse ram->videoram. This is only what I belive:) Ludvig Larsson
