The Nouveau driver performance is slow and jerky because the nVidia
hardware is still being reverse-engineered and the driver is still
under heavy development. You can take a look here

  http://nouveau.freedesktop.org/wiki/FeatureMatrix/

to get an idea.

If you don't insist on using Nouveau under Fedora, you can use the
nVidia closed-source drivers just like in Ubuntu. The procedure is this:

(1) install the rpmfusion repo [1] (if you haven't already),

(2) do a "yum install kmod-nvidia" (it might take a while to finish
because rebuilding the initrd is heavy, be patient with it),

(3) reboot the machine.

After that the nVidia driver should be active and everything
graphics-related should be very smooth and silky... :-)

HTH, :-)
