My kid loves playing SMC (Super Maryo Chronicles) on my computer, so he'll use 'switch user' to get his own login on there. Unfortunately, the performance is so sucky, that he's given up on it for now.

And I'm not willing to let him login to my account either!

So, my question is, how well does the r300g driver work with an X1650, AMD Athlon X2 5200, 4gb RAM, 1280x1024 display? I'm also running Ubuntu 10.04 with the xorg-edgers repository for my MESA and other drivers.

I'd love to try the r300g driver as well and see how the performance is.

Would it be possible to include games like SMC into your mix as well? It's OpenGL, but a different sort of stress compared to the others.
