Open up your /etc/X11/xorg.conf file and look for your NVidia card.
It'll be in the "Device" section and using the "nvidia" driver. In
that section, look for the following line:
Option "OnDemandVBlankInterrupts" "on"
If you don't have it in there, then you need to put it in as "root"
user. Feel free to ask how. Putting it in there will cut down the
interrupt usage with Nvidia cards.
