Finally got AC since .. two hours ago, what a phenomenal game/sim. First track I tried was Joux Plane with the P4/5, got stuck in a hairpin
But I understand what you're feeling there. But for me at least its partly because the tracks we have for now are sort of "clinical", and I don't really have a sort of connection to all those italian tracks.
btw, what a difference that flip size queue thingy makes
edit: in direct comparism to LFS the AC engine sound is a little unsatisfactory. I mean its really nice when you go WOT down a straight, but tip-toeing round a corner with like 20% throttle it sounds off, not fitting for the load state the engine should be in. LFS does this better. The gear whine on the other hand is really nice and changes upon load
