I have read in several places that micro stutters can be reduced to a small extent if the program priority is increased from level 8 (normal) to level 13. This can also be done from the Process Explorer - but it is difficult to call it up, find the MSFS among the processes and switch it over. That's why I created this small program, clicking on which "Flightsimulator.exe" takes you to level 13 (Attention! The simulator must be running by then!)
I could only test it in the Steam version, but it should work in the boxed version too!

Have a good flight, many soft landings!
