I posted this over at the TW forums as well, but I thought I'd post it here to see if anyone had seen the same thing.
Since the release of SF2:NA, it seems the player aircraft and the AI aircraft fly at a different angle of attack. I'm using a merged install of all SF2 titles and expansion packs patched to May 2012. This occurs with all aircraft, both stock ThirdWire birds and third-party aircraft. I have the difficulty settings at "customized", with everything but the flight model set on Normal. The flight modelling is set to "Easy". I've attached an example of the issue, using the stock F-100D.
As you can see from the above images, the angle of attack on my wingman's plane is clearly higher than mine. This is with the wing leveler engaged and holding a steady altitude, so it isn't mistaken for climbing or anything like that. This is reproducible very easily for me (pick a plane and fly). I was curious as to whether this was a known issue or had been reported?
I'm assuming this has something to do with the AoA of the taildragger planes, too - a possible side effect from the fixes to those?
