Not buying it. I see a substantial improvement with AFR turning off Motion Blur/Light Trails. I have seen AFR drop performance. But disabling Motion Blur/Light trails fixes it. Oh and I do hope you realise. The intro scene where the racers are lined up is extremely CPU limited. Either way I mentioned the game will be vastly CPU limited in many scenerios so if you're expecting your performance to double in every situation you're going to be extremely upset. I have to play the game @ 1600x1200 with 4xAA to even get my card completely GPU limited with a single card.
