On reboot Unity failed to load, dropped to a console and ran

Seems to be working again, however performance is very poor (just testing wine + World of Warcraft) and vsync is stuck OFF so everything tears and is horrible.

OT: Previous to this, WoW was running 15fps on the MESA driver (Intel chip) and using fglrx pushes 17fps
