Well any decent video card is going to have: hardware cursor, bit blitting, and line drawing. The better ones are going to have scaling, polygon drawing, maybe rotation. The best (3-D accelerators) may have 3-D polygon drawing, Phong shading, and the like. I'm sure that you could accelerate DPS by fully utilitizing the bit blitting facility (caching fonts in extra Video RAM) possibly scaling and/or rotating them, or even drawing fonts as vector polygons. The point is that I don't think there is any video card that you can feed raw Postscript to, and have it interpret the commands, as you seemed to imply originally. ---Jake
