Good news! We, with a bit of information from ATI, have been able to fix the delay problems with switching modes in the ATI Mach64! It will be available in the 1.0.4 Inline driver. Basically, for those techies who want to know, the problem was that we jumped to ATI's BIOS Query function, which called their VESA implementation. Their VESA implementation read the information from the ATI EEPROM. The speed problem comes in whenever the EEPROM is read, the BIOS waits for a vertical sync… Thus the slowdown. The fix was to turn off the video output before the call, which avoids the vsync delay. Switching modes only takes a second or so now… Chuck Walbourn – Vibrant Graphics PS: I have been asking Autodesk for release information on 1.0.4, but I am still waiting, so I don't know when the fix will be available, but it should be very soon.
