There is a chance the degradation in some cases is caused by the composite rendering timer drifting out of sync with your monitor. And it does, I know that for certain. When this happens, tearing becomes more visible and the frame rate can go down to half of what it should be.

The fix will be available for testing in a PPA after it's been approved by more reviewers... It will be worth trying at least.
