More FPS is not guaranted. Some people had a significant increase in DX10 mode, other people had significant decrease. The performance is closely linked to the quality of your hadware and even more for to the drivers !
In any case, a majority of people is reporting about a large improvement for the blurries when flying low and fast.
I don't know yet for the old mono-core CPUs, I asked on another forum, waiting for feedback.
By the way, Alrot, you have such a mono-core CPU right ? Just like me. Did you get any improvements with blurries ? I mean, can you fly faster without getting blurries ?
Sorry Daube I didn't see this,I assume with Acceleration, Definaly Yes, and the texture quality too, the best, beyond the mission and the new planes, are the quality ,its permormace, Its my opinion..
;D
