All in all a nice patch...

[Ataros]

Guys, if you read the patch notes the purpose of this alpha-release is not to make our flying more comfortable or enjoyable but to collect crash-logs and crash-dump files. CTDs of different nature (and specific to user hardware) are hunted and fixed one-by-one as goes from naryv's comment @sukhoi.ru I refer to here http://forum.1cpublishing.eu/showthread.php?t=31835

They reworked the core of the engine (multi-threading, etc.) and only now they will start fixing bugs with our feedback. Disappointing ATM but still very promising.
