I increased my FPS to 90 in Virtual Desktop software and that seems to be helping. I also set the IHADSS to display in both eyes instead of the right as default. Not sure this fixes anything but does make seeing the IHADSS better. I have hard wired router and headset. Nothing runs through wireless on my system for DCS.
I'm going with framerates as the basic answer to the concerns I had of jittery or nervous IHADSS display in VR. Thanks for everyone's input and descriptions of solutions.
I can only imagine what the next 5-10 years of VR will get us. What a time to be alive!
