Their tests were probably just on the function, not on the performances. In any case the work around is easy:
You can detect the type of device with SystemParametersInfo(SPI_GETOEMINFO,...);
When you detect that you run on a 3800 series, you should:
1) assume that GXIsDisplayDRAMBuffer() returns False
2) Never call GXBeginDraw, and assume that it returns 0xac0755a0
3) Never call GXEndDraw
4) Assume that the properties are:
cxWidth = 240
cyHeight = 320
cBPP = 16
ffFormat = 168
cbyPitch = 2
cbxPitch = -640
NIech ktoś to rozkoduje i tu napisze!!!
