Update.
I first ran EDTracker by itself assigning yaw, pitch, and roll within the DCS software. It worked very well and I saw no loss of tracking.
The first experiment (that is after the stand alone test with EDTracker) failed. It seems when you use TrackIR software it overrides joystick input even with yaw, pitch, and roll disabled in the TrackIR software. However, the X, Y, and Z axis (functions that were left in the TrackIR software) were still working.
I am going to attempt this again with FreeTrack software. This experiment will be carried out using EDTracker for yaw, pitch, and roll and using TrackIR Pro Clip for x, y, and z axis. For a camera I will be using the TrackIR 4 camera.
Apparently you can somehow make DCS think the EDTracker is TrackIR by using FreeTrack. I am hoping this will allow me to use an EDTracker/TrackIR combo. I will have to figure out how to do this. I also need to figure out if it is possible to do this through TrackIR software.
