Okay, that's not much worse than here, so it seems like your hardware should be capable of similar performance in hypertorus as well. > The next thing to try might be to install the drm modules that came > with the mesa library. There's no such thing. If you mean drm-modules-source, that's deprecated in favour of the DRM modules in the kernel. > I would expect that like CPU operations the GPU operations can be > optimized so a later code could have better results.

I'm not sure that's an accurate comparison of the documentation provided by these vendors, but anyway I don't think the low performance of hypertorus on your system is representative, there just seems to be something weird going on there. BTW, what's the number of polys displayed by hypertorus? -- Earthling Michel Dänzer | http://www.vmware.com Libre software enthusiast | Debian, X and DRI developer -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
