The only question which springs to my mind is whether you're using the
Mesa software graphics drivers or the binary drivers for your graphics card?

I think that this should give you a clue about which driver you are
definitely using (without poking around in xorg.conf).

$ glxinfo|grep vendor
server glx vendor string: NVIDIA Corporation
client glx vendor string: NVIDIA Corporation
OpenGL vendor string: NVIDIA Corporation

Plus to test your opengl performance you can run the following - if it's
really jerky then that's probably due to your graphics card:

$ glxgears

I get between 1500 and 2500 FPS for reference.

System->Administration->Restricted Drivers Manager is where I enabled my
binary Nvidia drivers - they aren't open source so Ubuntu disables them
by default.

I'm not an expert so I'm sure you'll get better advice but hopefully
this will get you started.
