It's actualy 75.94 Hz., Horizontal Sync 62.5 kHz, Pixel Clock: 85 MHz.

Yea.. well, only if you run at maximum resolution for very long time.. Like 60 minutes, which I don't routinely do. Also I discovered that in the past (before I shoved the cards around), the PCI network card and S3 Virge card were sharing an interrupt. I am not sure if interrupts are even used in DMA on the PC.. I didn't think so, but I am not a PC programmer. I just know that on my Hitachi boards the DMA controller can generate an end of transfer interrupt. Also, I currently have no video.. Audio only, but I probably screwed something up in the recently reorganization. > Well, at least you can do ximages and the CPU load isn't heavy anymore.
