CLOD not activating GPU properly ????

[Torian]

Crossfire and SLI either don't work or don't work properly at this point.
I know its a single card but the game sees it as 2.
Those of us with high end single cards are getting 60fps and great graphics with most settings at max.
You need to uncheck SSAO and anti-epilepsy filter.
Experiment with settings...eg, turn shadows, trees & grass off.
May help but I'm not confident that with that card it will work.
