low performance on mac

I can't take a screen shot, but it should be the "..." on your game menu. That is the Options menu at least in the English version. When you go into that, you should have the option to play either in Windowed mode or Fullscreen mode. Sorry, I don't know Russian so I'm only going by my game. The screenshots I took do not show the menu. Sorry.

Fullscreen on an iMac with a 27" screen running Yosemite 10.10.2. 

In the American version if you look at the Build/Buy menu in the upper right hand corner of the screen, you should see all the way at the end of that bar a "..." which if you put your cursor over it it should say "Options menu" or at least "Options". You click on that and go to "Graphics Settings". From there you should be able to change from Fullscreen to Windowed mode. You can also change your graphic settings (Low/Medium/High) and the resolution of your game.

Tremayne isn't their an option to include the UI's when you take screenshots? I thought the C key does that if you select the right box.

I can't change the FPS myself on my iMac. There is a way to monitor it so I'm told, but the instructions are found on the Sim4 game forums. Have your tried turning the Edge Smoothing Off? Just trying to run through different options.
