YES! i test Heroes of Newearth today with the latest oibaf-mesa8 ppa and yes now i can play the game.
the graphic is stunning good and no graphic errors.
I'm sure the radeon driver right now beat the Catalyst/fglrx in HON because HON runs like Upper CRAP on FGLRX just watch phoronix forum in the Catalyst amd part: http://phoronix.com/forums/showthrea...ghlight=heroes
The Radeon driver become the Gold standard for hd4000 cards because of this OpenGL2.1 Catalyst driver regression.
