Whoa sweet you have it too! Anyway as I've stated before, It's simply unplayable on ultra high settings, especially on high resolutions (900p and above). I have to set it between medium and high, plus there's always that annoying slow scenery loading in the middle of a flight. I can achieve an average of 25fps @720p.
I'm not sure about the CPU/GPU usage part, I didn't check. But basically I guess my GPU cant render it at high resolutions with decent frame rates - I can max it out on 800x600 with a minimum fps of 28 in some locations, but it looks blurry on my screen at that resolution.
I want to upgrade to achieve these graphics and frame rates at a high resolution, hopefully.

Bunch of scenery mods and add-ons like the A380 should be installed first.
