Please try installing drivers provided by your gpu vendor, and see if matters improve.
I installed fglx (or what's the name?) via terminal sudo apt-get install etc etc and after that I have had the same play experience as before.
I just bricked my kernel, don't install the Catalyst drivers unless you've done it before and it worked!
