The higher precision would be needed b/c updating and rendering 
takes time, so the sleep time would be timePerFrame - 
timeSpendOnRendering.

Problem is you'll need vsync anyway to avoid tearing. 
Applications that use their own timing to limit the framerate 
without using vsync are easy to recognise: they have a tear 
slowly moving around on the screen. It's visually even more 
annoying than regular tearing.
