Crazzyness with Compiz Fusion

So Compiz Fusion is super cool....... when it works smoothly! When I first installed Compiz Fusion before when it was still known as compcomm or actually no name at all, it worked flawlessly, and super smooth compare to when I used to run beryl. And that was saying a lot because my old nvidia video card only has like 64mb of video ram! But anywho now it seems Compiz Fusion is getting inconsistent. After some update sit runs brilliant and then sometime its just crap, eating my cpu. OK now that I have let some of my steam blow off, I know Compiz Fusion is still only alpha but I can't live without it.
