Gallium and Slow Performance on AMD HD4350

http://askubuntu.com/questions/285943/ubuntu-13-04-and-ati-amd-video-drivers

It seems as if i’m having significantly slower performance in X11 after upgrading to 13.04. I’m sure it’s related to the switch to Gallium. I’d like to either improve the performance with the existing software or switch back to the proprietary drivers. Does anyone have any suggestions?
