After all the discussion about TSENG 4000 cards being real speed demons, I decided to upgrade my old VGA card to get better Windows 3 performance. So I bought a Mentor 512K card locally for $130. It is a 16 bit bus, TSENG 4000 card. But a speed demon it isn't. It takes it about a half a second to redraw the 256 color (640x480) desktop wallpaper image that I use. This is exactly the same speed as the Pro Designer (TSENG 3000) that I use at work. To speed things up, I have tried using the Windows 3 drivers for the PD II and the Speedstar -- No change. I have also tried various BIOS shadowing and bus speed options, but no major improvement results. My system, by the way, is a 20 Mhz 386, AMI bios, 10 Mhz bus speed. The Mentor diagnostics state that the card is in 16bit mode. Any ideas? Or is this just a slow card design? Any happy (speedwise) Mentor users out there?
