Game performance does not change when I change the resolution

I have a sapphire 7950 and a 27 in monitor that goes up to 2560 x 1440. To get better performance in games I usually go to CCC and select "use centered timings" so I get bars around my screen so 1920-1200 doesn't look so muddy or stretched. However, when I change from 2560 x 1440 in game to 1920 x 1200, I don't gain any FPS at all! Sometimes my FPS even goes lower when stepping down to a lower resolution. This really does not make sense to me. This occurs in both Far Cry 3 and BF3. Any ideas what to do? Thanks

I should add that if I go back to native resolution with no black bars around the screen then go to 1920 x 1200 which makes the screen all blurry and muddy, then i get the performance boost. It's basically only when I have the black bars around the sides that my performance doesn't change.

It might be a driver issue in which not running the monitor at native res causes issues with scaling.
I really can't see an i5 2500k @4.2 bottlenecking any single player game.
Which drivers are you running and what is "low" fps?

:o  That's not possible amd drivers are on par with NV now days. :lol:

cant you just run in 1920x1080, then use your monitors menu to scale it to black bars rond the outside? rather than using ccc's display output options. If it were me i'd rather keep the native resolution and drop back other game details, it would look a lot better than full detail and lower resolution.

just realised you said 1920x1200, which is a different aspect ratio to 2560x1440. Try 1920x1080, it will scale better on your monitor and should look less blurry as its the same aspect ratio.

Haha you'll get issues from both sides with some hardware combos :p 
Guess i've just been lucky and no issues from either side :) 
I've always liked the CCC layout better though compared to nvidia

EDIT: I hardly use the supplied software from both nvidia or amd as i prefer other programs.

my monitor does not have a menu since it is an imac display, and although it is true that higher resolution and lower effects does look better, I'd rather get all the performance I can get. I honestly don't even understand how this is possible. I'm getting 40-60 FPS in battlefield at 2560 x 1440, which is by all means playable, and I guess I'm fine with playing that way, but it's just bugging me that if I wish to get better performance, lets say for BF4, I'll be getting the same FPS at 1920 x 1200 as I do with 2560 x 1140, and it's kind of annoying. Far Cry 3 for instance is another example, I would like to get better performance since that game is very intensive, but I still get the same 30-50 FPS that I get at 2560 x 1440.

Is there a way you can scale to 1200p without adding the black bars?
