Guys I bought the the russian version. Everything that has been said about the game is true, in the current state, it is the Silent Hunter 5 of flightsims.
I cancelled my international steam order now cause the game was running SO bad on my i7 920 processor (12gb ram, hd 5850). I can run crysis 2 on best graphics and resolution and it runs like a dream.
Maybe it will be great game in one years time, but it was definatelly released way too early. There is so much work to be done still.. lost of bugs and the fps is really bad. So just prepare yourselves, there is no way you can enjoy this game much
Sad thing is that the reviews of this game will be murderous - for sure.
