I can't get precise time, but, with old BitBlt(), not a 800*600 bitmap,
I set tick count array in program, tkCount[15]-tkCount[14] = tkCount[14] - tkCount[13] ... = tkCount[1] - tkCount[0] = 170 ms around.

Then I use new BitBlt() to load 800*600 bitmap, it gives 400ms around.

So I should say it added 230 ms.

Old BitBlt() just transport about 1/5 or 1/6 part of 800*600 bitmap.

I expected to use a 800*600(the screen area) memory DC to hold all parts changes, then BitBlt() to screen.

Now that 800*600 tooks so much time, I don't think a double buffer technique is helpful.
