Ok, I solved the problem partly. I opened a new profile and then it seems to work fine. Then I changed the setting to my favorit behavior and saved them. So it still works fine within FSX. 100FPS, ~30JPS, smooth tracking,...
Then I restarted my PC and then the same problem occurs with the new profile... tracking stopped after seconds.
then i tried another new profile and it works. i changed the settings again and everythings seemed fine. but than i changed to SimConnect (only) and then the FPS went down to 30... with JPS around 35 and over 80% CPU usage!?!?! so i switched off the simconnect and everything was fine again.
so i saved the profile, started FreeTrack again and... nothing... it stops tracking again after seconds....
that makes me crazy...
Do you've any ideas, how to solve this problem?
