I have tracked this down to the ATI Driver 12.8 from AMD/ATI Website, i was messing around with the Kernal 3.5 when i ran into problems installing the ATI Drivers from AMD/ATI website after a lot of fluffing around and returned system back to kernal 3.2 i uninstalled 12.8 driver and delete left over files then i just went to settings then "additional drivers" and activated ATI/AMD Proprietary FGLRX Graphics Driver, rebooted and now the game loads and plays, also noticed L4D running with wine is also running smoother as are ID Tech Engine Games, i did not use the (post-release updates) as it always fails to install for me.
Hope that helps.
