$ glxinfo | grep render
direct rendering: Yes
OpenGL renderer string: GeForce Go 7700/PCI/SSE2
    GL_NVX_conditional_render, GL_SGIS_generate_mip map, GL_SGIS_texture_lod,

Yep, glxinfo says I can render. glxgears seems to run fine. Although I
haven't looked into it much, it seems my framerates are low when I
compare with some random person who posts theirs on IRC or this
mailing list.

When I watch glxgears while not doing anything else on the computer,
it will get around 6200 FPS. If I switch to another workspace, that
will (naturally :) jump to around 10500 FPS. But if glxgears is
running on my current workspace and I'm doing other things, like
moving other windows around or switching tabs in Firefox, the
framerate can drop to below 5000 FPS.

I haven't really tried any games, not tuxrace, but I have launched
Frets on Fire [1] once and fount it sluggish. Haven't had time to play
that since.
