I was using Leo4All at 10.5.4. I wanted to be able to download updates straight from apple, so I decided to go with Vanilla. After installing the vanilla kernel, it seems performance has gone down. I see this when switching windows and during some movies. Any ideas on how to fix this?

GPU: eVga 8800GTS 320MB
CPU: 2.13 GHz Intel Core 2 Duo
