Is this true of any graphics card which is compatible with X, or only
the cards for Jaguar? Because the results for the PCI Radeon with
the Jaguar hack are certainly mixed. And the Rev C motherboard has a
supported GPU on it - just not supported for Jag. Am I right in
thinking that OS X will revert to a pre-Jag form of acceleration on
the stock GPU? Or no acceleration at all?

320 megs already - adequate?

Cool. Gotcha.

Wow. That seems kind of, well, dumb.

This is under 10.2 with/without Jaguar, or an earlier OS?

It's on the motherboard, Rage Pro with 6 meg
Thanks guys for your advice.
