Well i think i need to back Matt up on this one.. just got the Dogs this morning and while playing on Extreme Preset and dipping down to.. yes.. 37fps on my overclocked 7950.. it actually does look and feel smoother than what 37fps would feel like in BF3.
Honestly mate i duno what it is.. maybe its something to do with the AMD cards that make it run smoother at lower fps but im not kidding when i say that when i go down to around the 37fps mark it still runs smooth.
Anyway i havnt really got too much into it yet and only played about half hour or so into it so maybe things will change once i start driving vehicles.. we'll see what happens
