True. Since VDI functions take advantage of the BLiTTER if it's there, programs written to use VDI graphics primitives will show an increase in speed in graphics operations > > 2._____ The desk top speeds up with the blitter on.

False. Jim Kent's CyberPaint takes specacular advantage of the BLiTTER, and I'm sure other examples exist (though I can't think of any at the moment). -- Ken Badertscher | Hey, umm, the stuff I said up there Atari Software Test/Support | is, like, what _I_ think, okay? {portal,ames,imagen}!atari!kbad | So, y'know, don't bug Atari about it.
