I recently got NullDC running on my new laptop. It runs @ a full 60fps no problem, however the sound is really choppy/full of static. I've tried the Chankast sound plug-in, but it causes everything to run way too fast because there's no sync/throttling. Any ideas as to what could be causing the sound break-up? I don't think it's a speed issue....un-throttled it runs at 140fps!
