I understand that. But worse than BO2?
In every way, yes. On every platform.
I have the PC version and have thrown a high end crossfire rig with an i7 at it, and dropped details (with no antialiasing!) and it still runs sub 30fps most of the time at 1080.
The compromises are worse on other platforms. The games runs like ass on (I think) pretty much everything except the 360.
Meanwhile my same rig handles BF4 maxed out at 1080p looking much better. And BO2 with everything maxed out and at 1080, looking much nicer.
