Anyone?
I coded my own ASM MS-DOS picture routine, which uses 32bit
instruction codes to transfer pics onto, say a 800x600x16 screen,
on my old SiS 5597 chip, the FPS is around 15. Later I use DirectX
to do the same, and it goes around 100 over.

This is due to Windows hardware acceleration function, besides
asking the driver to accelerate the hardware...

So, anyone know of the instruction codes to accelerate VGA chips?
