I ran Crysis 2 DX11 with my 6970 x 3 as soon as the 1.9 patch was released, and the results were as follows.

It seems normal when DX11 mode is disabled, but once it turns on the CFX scale is bounded by 2.
A few days after I reported this phenomenon, Catalyst guy left a msg on his twitter as follows.



At that moment I really appreciated their speedy reaction. But...

...a week later, the same guy left another msg on his twitter.



What the f**k?????

3 and a half months later, yes, today, the issue still remains active and I'm still struggling with that.

Here's an image of GPU-Z screenshot while running Crysis 2 DX11 with a pair of 6990s.



GPU usage seems like it's bounded above by 50% so that the sum of all can lie within 200%. Why???

...I'm dead serious, man...

Try again with minimum graphics settings to see if you aren't CPU-limited.

Thanks for reply, and I'd already checked this with a variety of CPUs (from i3 2100 to i7 2600K, including Thuban and FX-8150) and lower res/options though I didn't attached data thereof. Trust me!
It seems obvious there's a kind of 'lock' or something... Not sure whether this' from Catalyst or the game itself...
