Chris,
I was just looking at one of the other posts. If your problem is the
video card you might try tuning the PCI latency. Check out my page -
http://myweb.cableone.net/eviltwin69/Arcana.html. There are a couple of
links that cover latency really well.

Agreed. Your system should rock like crazy except for one leetle
problem. IRQ 9 is higher priority than IRQ 10 so every time you get
disk activity you're probably dropping audio.
Yeah, that's what I would have *expected* -- so I was really surprised
when the latency tests didn't work out that way. Playing PCM audio
while writing, then copying, a 1.5 GB file (half again as large as my
RAM, so can't RAM-cache it), with my disk over 90% full, still produced
what I *think* (if I'm understanding all this correctly) are pretty
good numbers (100% within 1ms of the fragment latency). But I do plan
on tinkering with this, especially if the performance is troublesome
when I start doing real stuff.
But while the disk results looked good, the graphics results weren't
very . . .
