I reinstalled all the drivers and software this morning Jan 19th, and now Arma 3 is working with no problems. Might need some tweeking but no issues and very smooth motion of the camera. Thanks. I did NOT have to manually change any settings in the config nor did I replace the opentrack.dll (I am not sure if the current install is corrected).
I installed the drivers, got a message there was an update, installed that, and then Infinite screen.
I have not tested IL2 BOS yet.
