When messing around with a friends windows installation, I've accidentally discovered that just opening NVIDIA's fancy control panel (and keeping it open) does the trick and lowers the CPU usage to around 5%.

P.S. I did that to enable Triple Buffering which is what I use in my linux installation to lower the CPU usage.

enabling tripple buffering and/or vsync has no effect,
