OK, fixed the rudder issue. It was caused by my
Logitech utility, had sensitivity set way too low for this game. I do that because in DCS it is way too sensitive if I don't do that. Disabled the
Logitech utility and now have full rudder defelection and can take off in a straight line.
Now to work on the 144hz issue. Some games allow you to select the refresh rate and that is how it should be in all games.
Yep, fixed the refresh rate issue now. Use Nvidia Inspector and override the game settings and tell it to use maximum refresh rate if you have a high frequency monitor.
