I made a long flight using Lionheart's Pasped Skylark, which transfered automatically from the MP. It had no instrument dials, or faces, but the needles all worked! Most buttons and switches worked, but the scratches in the plexiglass were extremely excessive. Anyway, I paid attention to my fans and heat out put in the exhausting air, especially through the CPU radiator. Did not notice the fans being any louder, but there was definitely more heat coming from the radiator. The case exhausts were not noticeably warmer, including the exhaust from the GPU. I was flying in and out of clouds, and getting blown around quite a bit from the downdrafts, flew over Los Angeles, California with never a stutter a noticeable jump into view caused by LODs. The scenery was smooth and natural in viewing near to far. Mountains did not change constantly, clouds did not "pop" into view, and vegetation only came into focus as I got closer, it did not "pop."
