Time to add my thrupence' worth.
After lots of weirdness, every reboot seems to have reduced the problems. I found problems aplenty (from spawning at a thousand feet, having my controls reset, etc) but all seem to have solved themselves. Thank goodness My CEM has come back (it was missing there for a while!) and now the game feels a lot lot smoother.
Yes, there are still glitches in my game. Today first there was no aircraft sound. The second time, the sound had come back but the skin was missing on my Spit. Third time, it was all there, but yes, the brakes were on. So, pumping the brake is a must, as is opening the rad, since the Spitfire at any rate comes warmed up nicely. In fact, if you're quick, on spawning I found you can hit the fuel pump and keep the engine going (but remember to open the feckin' rad).
Obviously, it's a bit rough and ready, but
this is a feature we'd been hoping for: a pre-warmed engine. And they've given it to us. Presumably, eventually there'll be an option for it. They've just got to iron out the implementation.
I've found the AI better, and ground handling seem to have changed. Eg. my Spitfire Mk II got to rotation speed OK, but took an age to get faster than just above stall speed (I'm slightly concerned about the behaviour of the Spit's throttle - very little change at the top of the curve), so it is a while before I am able to start to climb. Landing, she took much much longer to slow down (In fact my AI wingman landed first (Hey! It landed!), but overshot the runway...!), so I suppose getting the landing speed just right is going to be more important.
I'm impressed, my faith is restored and all's right with the world.
Thanks Devs!
