Blt vs BltFast... Rag on a Stick (4 replies, 0 views) (2000-Sep-16)
-
From the SDK: "The software implementation of DirectDrawSurface7.BltFast is 10 percent faster than the DirectDrawSurface7.Blt method. However, there is no speed difference between the two if display hardware is being used." Maybe I'm just not an optimisation freak, but isn't 10% just a little... small to bother with BltFast when Blt is easier to use and has more functionality? Sure, it all adds up, but even still, its only faster if display hardware is being used. What type of display hardware are they talking of? Is my moniter display hardware? I think it is, since it isn't software, and it displays stuff. (Now I'm getting podantic). Is this like 2d accelerators? And is there no speed difference because Blt is faster or does BltFast slow down? I'm confused (in case you didn't realise). Any thoughts, comments, facts, speed test results (I'm too lazy, and I'm still learning DDraw) would be appreciated.
