FX-6100 HD 7850 30-50% usage tech demo

So, maybey its asked before, and it might not be helped yet but its good for people to know....
I found out that the tech demo does not support the fx 6100 very good, (might be architecture problem?), it also uses only about 4 cores, maybey i am doing something wrong?

I played on 1366x786 (something like that) in windowed mode for editting mode.... also, screen was taken while flying/crashing trough the air...

 

Maybe because these processors are much powerfuler than demo need, i have FX - 4100 and it uses it fully

 

Thats definately not it, because my fps is around 20-30, i would prefer around 50-60, it would be much higher when all my power in my cpu AND gpu where used... but it drops sometimes and its a little bit annoying, also, to crash into another car is not possible with this kind of framerate with just a single car...

 

Hmmm, ok maybe i'm wrong) about cars, it's now much better made than it was in ROR, when i drive near another car in ROR my FPS drops to 5, now it's always 25-40 to me)
it only drops for a second when i first time after loading crash into something)

 

Unfortunately i dont have Drive, so i cant test it out with two cars, i just made a assumption... i may get it after i annoy my parents to let me use MY money to buy something online....
