Well, I'm using a basic (well, almost - SVGA, but 256K, and no blitter, etc) VGA card at the minute, although it's an Oak OTI-37C, so I've got the UniVBE program running, meaning I can forget supporting non-VBE cards if I have to, but how many cards are there that have bad or no VBE support still ? Basically, I want to know that the graphics will be as fast as possible on a basic card like mine, and a top of the range VESA card (at least, as much as possible without separate drivers for every card). There are a lot of details in the way though, like whether I should use Mode-X with two pages (under the assumption that the VRAM access on a good card will be fast enough), so that the card's blitter can blit straight into the hidden page, or whether to use the standard "chunky" (non-planar) mode, giving the processor all the work except the final transfer to the display. I guess you can't use the blitter for system RAM to system RAM copies can you ? Hope someone can help... - Lee. -- Lee Braiden (lee_b AT celestia DOT dnet DOT co DOT uk)
