RE: Bltfast Adam Hoult (2 replies, 0 views) (2000-May-6) Bltfast does work wether your surface is in vidmem or sysmem. Basically what the SDK means is that Bltfast attempts an asynchronous blit using the hardware implementation of the function, but can only do this if A) The surface is in Video Memory, and B) The hardware supports it. If either of these are not true, it still Blits, but not asynchronously. In these cases a Software Implementation of BltFast is used.
"The software implementation of DirectDrawSurface7.BltFast is 10 percent faster than the DirectDrawSurface7.Blt method."
Hope this clears it up as the SDK words this REALLY badly =)
P.S Last time i said that i was back, was a slight exaggeration, but i really am back now, expect an update very shortly indeed !!! =) WOOHOO.
