a few findings:
- Map in "General Melee" (SFMA) is borked, Rook and Bish strats are switched and thus deep in enemy territory
- Engine sounds are a mess:
Tu-2 has external engine sound only when the point of view is extremely close to the plane, 10ft away and it cuts off. Internal engine sound drops out depending on attitude (nose down and it cuts out no matter what speed & throttle setting), and depending on power setting alone as well.
At first, Lancaster had no engine sounds at all. Only when I went external and set my point of view very close to the engines, there was a faint engine sound to hear which then also stayed when I switched back to cockpit. Until I brought the clipboard up and minimized that again - engine sound disappeared again
In the B-25C I had internal engine sound in level flight only while WEP was on. Without WEP, engine sound only when climbing, unless I cut back the throttle ...

Tu-2 gauges flickering massively, in the B-25C the screws in the compas area of the panel are.
EDIT: Added current DxDiag
