Video is slow

[Roger]

I'm using Fedora 19 with the standard Nouveau video driver.
I've noticed that when re positioning gui windows with mouse, movement 
is increasingly glunky, jerking in 5-10mm steps in any direction. When 
dragging a border of a gui window the mouse moves to almost 100 mm 
before edge of the window moves.

I usually have the /home/rails-projects/project directory open, Geany, a 
terminal or two and a browser, opera, firefox or chrome. Geany may have 
several files open simultaneously.

CPUs run at about 60%. memory, 2gig runs at about 55-80% depending on 
what's running. Swap is at nil.
Have a 2 gig Geforce GT8600 video card which is very goo d at 3d Blender 
stuff.

I swapped over to Ubuntu 13.04  which uses the Nvidia driver and there 
is no problem at all with movement no mater  how many gui windows are 
open and operating. Ubuntu is so slow to open I hesitate to use it.
Mind you, lately Fedora 19 is taking sometimes over60 seconds to open.

Is there any fix for the Fedora 19 Nouveau jerky movement?

TIA
Roger
