Found a really effective way to speed up frame rate

[GFree]

For me it's the occasional crackle or brief interruption in the audio. It's nothing really major but it does manifest itself when things slow down, that's why disabling Beryl helped because as things sped up, the amount of audio artifacts reduced. Don't have anything lasting as long as you though.

You can try Urkle's OpenAL replacement in the stickied thread, but that didn't do much for me except make things worse. To disable Beryl I just run

metacity --replace

but that's with Ubuntu, so I don't know what you'd have to do.
