GPU never at 100% usage

Hello, my 7870 is never at 100% usage, thus giving me terrible frame rate. When I play BF3 it is only at 60% usage giving me an average FPS on 40. When I lower the graphics settings, the GPU usage also drops, giving me the same frame rate. This makes having this card utterly pointless to own, since the frame rate I get on all games it the same if not worse than my old 5750. Anyone know of a solution?

The 1045T is probably bottlenecking you a bit.

yeah but not THAT badly, i'd say try reinstalling the card in another pci-e slot

A bit? More like a bundle. Slow and creaky 2.6GHz Phenom matched to a brand spanking new card. OC it or upgrade to Ivy Bridge.

What is your CPU usage when in game ? Running the latest drivers 12.8 ? Did you uninstall the old ones using driver sweeper before installing the new ones when you put your 7870 in ?

I'd say overclock your CPU. You can shut off two cores in Windows to give you a better cooling profile, but BF3 is one of those games that like more cores.

install open hardware monitor,check what your CPU usage is while playing,If your CPU usage is 100% and your cards are at 60%,then it is a CPU bottleneck.

What motherboard are you using?
