Graphical aspect preference ROF vs COD and other stuff

[Mustang]

I JUST INSTALL ROF - only just curious
Then I go to play offline,

I rise up the ROF deafault graphics a bit, and do some clicks
I know the limitations of a NVIDIA 560 Ti
No Antialiasing
Aniso only x4
Only 4 Light sources
Other settings High or ON....But not at maximun

ROF RUNS WORSE THAN CLOD!!!! ( less fps) AND LOOKS WORSE !!!

I get 32 FPS ... 19 over the trees


My system

Win 7 64bit

AMD PhenomII 965 BE @ 3.8 GHZ

Ram 8 Gigas

Graphics Card NVIDIA 560 TI 1 GB 1600x900 , Drivers updated !!!


ROF GIVE LEES FPS THAN CLOD.

I CANT UNDERSTAND I PLAY MANY GAMES @ FULL .

Some settings in ROF, Kill my PC.
Where this optimization??? if I must put the graphics in medium.
