The game has potential but potential doesn't cut it, a definite 2.5 until its fixed.
It does not even support Force feedback, a staple of every sim for the last 10 years and even though it is multi threaded, its implementation is broken leaving it to run on a single core.
Might be fine given a lot more development time, but once the reviews start hitting, it may not get the time it needs.
Some users are sighting 1c's previous support of IL2 as a banner to wave as if to ensure it will get fixed, but 1c is a different company now. Oleg is no longer at the helm on this project, and support of il2 was passed to a third party years ago.
