IL2 new versions are coming with 128 player server capability. That is not much less than AirWarrior was when I joined it.
The servers for Cliffs of Dover aren't dedicated servers run by Ubisoft, they are player hosted servers, usually on their own systems or if they can scrape up some money on a rented server. If people complain about the lag on Titanic Tuesday, imagine the whines trying to play on a 128 player server that is being run someone's home desktop or laptop.
The less than 1% of home flight simmers that have an advanced sim pit (one that features glass gauges / MFD set up) sin't compelling enough to devote the resources needed to code these very niche items into the game.
I agree this game has to continue to evolve but pandering to less than 1% at the expense of the core game and the core audience is not a wise use of valuable resources.
