Low FPS, low CPU/GPU usage

So, whenever I go to set up a new game, and it "automatically detects the optimal video settings" or whatever, it tells me that I should be running Ultra High. But when I go to play Skyrim, SC2, or any other game on ultra high settings, I get a terrible framerate (like 12). When this happens, my CPU usage rarely goes above 40 or 50%, even during huge FPS dropoffs. In order to get a playable rate, I usually have to drop down to medium settings. What's going on?

I'm running dual graphics with a 6550D and a 6670, by the way.

50% CPU usage is a lot. Most games cannot use more than 2 cores.

Furthermore, did you check GPU use with MSI afterburner?

P. S. Don't expect to run many games on maximum settings with those specs.

Then why do games always suggest that I use the highest settings? :/

What power supply are you running? And SC2 is a pretty intensive game. 50% of the CPU is alot. But my guess is that the GPU is using more than 50%.

You have an unusual configuration, and these games must not really know what it can do. But your setup is not expected to be able to play on max settings. It just isn't that powerful.
