I have run Fractint (v15.0) both with my card's VESA bios installed and without it. (It's a Diamond Speedstar with the Tseng 4000 chipset and 1 Meg RAM.) The program draws things MUCH faster when I tell it to use the Tseng 4000 driver rather than the VESA driver (I'm guessing at least a factor of two). It's so much faster that I always use a Tseng driver if a given application has one rather than the VESA. Anybody know what's going on here and if the slowdown is due to something I'm not doing right? -- Mike Ressler - Infrared Photon Jockey ressler@galileo.ifa.hawaii.edu If at first you don't succeed, get a bigger sledgehammer.
