98.1% CPU Usage? What driver are you using? It looks like the OpenGL 
work is being done in software. Run glxinfo to see if you're using the 
NVidia OpenGL implementation, or if it's fallen back to Mesa. You may 
have installed the NVidia driver, but you may still be using the NV 
driver. Check your Xorg.0.log file to see what drivers it's loading, and 
look in your xorg.conf (or /usr/share/X11/xorg.conf.d) to see if it's 
being overridden in there.
