Slow Xorg performance on PPC Gentoo w/ Voodoo3

8-bitDesigner · 01-30-2006, 02:34 AM

Okay, I've got a tricky question for y'alls: I've got a Powermac 8500 with a Voodoo3 card and I'm afraid that the Xorg performance is somewhat less than stellar. I can get about 30fps in SNES 9x when it's running at the size of a postage stamp, but any larger an the performance drops off considerably, and Firefox lags when I try to scroll through pages.

So, the first question is whether or not I can speed this up and if my Xorg config is remotely close to where it need to be. Link here.

Secondly, and this one's a stretch, is there any way to get OpenGL working on linux *without* Glide? Sadly, Glide doesn't have a PPC port yet, and I'm not really holding my breath, however, OpenGL should be able to access (by my understanding) the Voodoo3 hardware without needing Glide.

Xorg.conf excerpt:

# This loads the miscellaneous extensions module, and disables
# initialisation of the XFree86-DGA extension within that module.

      Option    "omit xfree86-dga"   # don't initialise the DGA extension
