And what I found is that in areas like Boston just after you arrive, the game is incredibly CPU bound, more so with environmental effects set to very high. 

 

 

 

My current system has a 3930K at 4.5GHz and two 7970's at 1100/1450.

 

 

 

In some places, I could make the frame rate go from 27 to 43 to 60 (vsync on) by changing the environmental effects from very high through high to normal.  In one spot I just found, the frame rate was 26 on very high, and 32 on both high and normal.  GPU usage went from about 28% to 32%, showing that the CPU bottleneck was significant in both cases.  That's at 2560x1600, where most games should be bottlenecked by the GPU.

 

 

 

CPU usage for the game ranged from 22-32%, which translates into roughly 70% to 100% of four cores, since I have 12 logical processors.  I've seen at least one test which showed very little benefit beyond two cores.  It's certainly not using more than four, and the main render thread seems to be a bottleneck for other threads.

 

 

 

The upshot is, the lousy performance of this game is CPU-related, and extremely variable based on location, so anyone who says they saw improvement with a new nVidia driver probably didn't check the same area they measured before. 

 

 

 

   

 

   

 

 

agree about almost every thing but iam not agree about the nvidia part check this link and you will know why :

true story .......

 

 

Still can't get your 5750 to play on extreme?

 

well its 5770 and btw if this game works fine for me ( OR you ) on lowest setting i will be happy !!

im having problems too, fps drop from playable to down right fugly when looking at really dense forrest or boston rooftops... im about to give up on the game, iv updated drivers to no avail, im running it on a radeon hd 7670m so im guessing its a problem on the optimization side of things, shame really...

Same here.I use HD5670 GDDR5 1 GB.All settings are normal.

 

Normally i get 60 fps but when i came in Boston FPS drops down.

 

We need Patch or Driver.
