I've noticed one thing, when in cold and dark A10 my fps are holding around 43, but with all system started it drops to 34 (no TGP or any other resource hungry systems on MFDs). What's odd- in Ka-50 i have 44 fps in ready to take off heli.
Another thing- after 1.2.1 launch i wrote i have 25 fps flying over Batumi, where before i had around 40 fps there... What i didn't noticed is that it's not just Batumi- it's almost everywhere, city or not. Strange.
