Game laging way more than it should.

I have lowerd my graphic setting but even on the slowest speed it still lags quite badly. (unplayable)

I can play GSB without problems on best graphics and max speed

And my rig usually handles all new games on good graphics…

I am playing the steam version of the game, but i suspect it is my dual graphic card setup that is giving my problems (not the first time).

Are there any known issues with crossfire for GTB?

This seems to be a steam GUI conflict. Try running the game direct (from GTB.exe), without steam. Everyone seems to fix it that way for now.

Fixed it thanks
