VRAM requirements

Blitz3D Forums/Blitz3D Programming/VRAM requirements

jfk : Are both Front and Backbuffers in VRAM? For some reason I was thinking front buffer was in main RAM, but then how'd it get out through the graphic card?! 6 Mb cards sounds a lot for me considering my retro audience.

Still, a bit of research shows a Riva TNT+ from 1998 onwards should be enough no worries. It doesn't support DirectX 7 though. Will that be a problem? Can Blitz3D run on DX6 with reduced functionality?
