So I tried you day mission. I stayed in the default view(cockpit) for some time. All my settings are at MAX with 1920x1080 + 4xAA and it was an average of 5fps. Lots of units in there:music_whistling:
But the thing is.... my GPU's peek loading % was about 30, and my CPU never above 50% on 1 core. The core's loading was very uncoordinated(each core was running up and down like mad, but like I said, never above 50%)
But as a general benchmark, I thing a track with a define time would be wore suitable than a mission
