If you are a hardcore flight simmer I'd stick to flying in FRB mode. That's what most of us fly on here. That's the closest Warthunder will become to a flight sim.

I would say it's about even with IL2 1946 when flying in FRB mode.

Yes not all sim features are done yet in all the planes. Manual mixture, Prop, and Radiator controls don't do much right now in most planes. Some flight models are still pretty arcade compared to others. No bomber cockpits being a big one for me (but they are working on them!) Also flying non historical planes on certain maps takes getting use to, I really hope they do something about this.

But the game looks AMAZING. Great graphics, runs smooth on older systems even. Great music, menus. Plus it's FUN to play. Oh and did I mention it's FREE? You can't really complain about a free game that looks and plays this good.
