I hope they will solve the "Window in Focus Bug" with the patch

It is a bit annoying to have MSFS open in a window not in focus in order to use the sim without stutters and decent FPS but not being able to use keyboard and mouse.

To make it clear, peripherals like joystick/yoke, pedals, throttle quadrant etc. work properly whan the MSFS window is not in focus. Only mouse and keyboard of course can not be used. So could it be that mouse and/or keyboard have a negative influence on performance? This reminds me a bit on the infamous “mouse cursor bug” in FSX, which caused quite a loss of performance (stutters, less FPS etc.) for many useres when the mouse curser was visible on the screen.
