Thank you 
The framerate is in the upper left corner of the screenshot. I get between 20 and 25 FPS usually. Sometimes of course lower. Sadly the new update had my Framarate drop a bit lower than before on average. So I decided to post here and ask.
I will fly to some other places to see what RAM is used. That’s a good idea !
I seldom fly over big cities though. I once flew over Tokyo and FPS were dropping like crazy, so after that I stayed away from big cities. Don’t really care for them anyhow.
I will also play around more with the Graphic Detail settings to see what I can lower even more.
