Firstly I will just say I was getting 26fps maximum in the benchmark with full detail 4xAA and v-sync off @ 1920x1080 res. The game was playable but I knew my PC could do better. Tried all the hardware settings config tweaks, tried the audio tweaks, tried the everything tweaks..... What i didn't do and I just decided to try it (kicking myself) was to turn SHADOWS TO HIGH FROM ULTRA. With doing this I got an instant FPS boost beyond belief and you can't even tell the difference. I've now put it up to 8xAA and v-sync ON and i'm commanding a respectible 46 average FPS in benchmark and a solid 60 FPS in normal gaming mode most of the time. The lowest FPS i've experienced is 39 FPS starting a race at the back of a full grid. Give it a go and see.
