WebGL under debian, radeon driver

[Xavier Bestel]

Hi,

I'm using a debian system rather uptodate, with:
xserver-xorg-video-ati 1:6.13.1-2
libgl1-mesa-dri 7.8.2-2
libdrm2 2.4.21-2

and I'm trying to get various WebGL examples working under Firefox 4b7
and Chromium 6.0.472.62. Lot of them don't work, and the ones that do
are quite slow.
E.g: http://scenejs.org/dist/curr/extr/examples/hello-teapot/index.html
looks like 2 fps on my machine, which has a Q9650 at 3.00GHz + RV630.

Is that how it's supposed to be, or is there something not well
configured on my machine ?

Thanks,
	Xav
