Minimizes to windowed mode (Far Cry 3)

The game starts in a window, after a second in Fullscreen, during loading (pistol icon) flies out of the window. Because of this, you fall into the FPS abyss. Interestingly, when I run not FC3UpdaterSteam.exe, but simply FarCry3.exe, the game starts in English, but does not
crash out of the window, as a result: FC3UpdaterSteam.exe - 20 FPS (3840x2160)
FarCry3.exe - 50 FPS (3840x2160)

Yes two solutions - to force FarCry3.exe to launch Russian localization or to force FC3UpdaterSteam.exe not to fly out of the window.
How to do it?
