Dennis, I understand what you say. FSX and P3D (the ESP platform in general) was never kind to helicopters. The sync issue you talk about (where you see other players) have to do with the networking software used (IVAO, VATSIM, others) than actually FSX.
The team told me they want to do it right. I believe in them. If they actually do it, well… That’s another story and we’ll have to wait and see. I am hopeful, yes. But if they mess this up I will be disappointed for the missed opportunity. Not so much for the “fail”.
Right now we don’t have anything else than we have (weird sentence, I know). What I mean is that we have X-Plane, DCS, Aerofly FS2, FlyInside and FlightGear that provide decent helicopter flight dynamics.
If Microsoft does it properly, great! If not, it’s business as usual for me. I will keep on using the sims I use right now. Yes, the scenery is incredible in MSFS but if I have to choose, I rather have good helicopter flight dynamics than pretty graphics, hands down.
