When you tab over, it removes the video rendering load. Your cpu looks 
to be a bit on the wimpy side. Have you tried things like setting "Use 
Events" to true in your xorg.conf? I found that setting the video slider 
in nvidia-settings to performance from the default of quality made a 
difference. NVidia driver 9577 here.
