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.
