Nope, I tried native tracking too. Same thing. Reinstalled VorpX. downgraded drivers. Went to the lowest possible resolution, still get it. Tried safest, safer, fast. All the same. All arma settings low as they will go (well some like shadows kept on high, otherwise arma moves them from GPU to CPU).
Just found this helpful info

Note that default soldier FOV is 14/15, that explains why native values aren’t working. Vehicles actually have a variable zoom based on speed, gah. Somebody’s gotta make an Arma mod to fix all this crap.
I have. It works great. Head tracking works in vorpx, so Opentrack isn’t required any more. However, I like opentrack better because its got perfect 1:1 tracking, while the vorpx is still mouse based, and takes some tweaking, never quite feels the same as opentrack.
DirectVR only uses 4:3 ratios, and the FOV isn’t quite perfect. Mentioned it on reddit, and Ralf noticed it’s off too. The value is calculated for the headset, which should be perfect, but Arma uses some zoom. Its pretty close on stock DirectVR settings, and will get tweaked in the next release (from talking to Ralf on Reddit). Helicopters use a slightly more zoomed FOV from on foot, so that takes even more tweaking. I highly recommend mapping analog zoom to a slider/rotary. I use the friction control on the warthog, its perfect. Lets you easily tweak it realtime, just swing your head left/right until things stop swimming and look normal.
There’s always issues with FPS. I get a strange double image when moving, like every other frame is one behind. Locking ASW 45fps makes it very obvious. You can still play, but its annoying. When i (rarely) get the FPS up to 90, it goes away. Since the best you can usually do is somewhere between 45-90, its not ideal. Someone mentioned judder issues w/ 18.0.3 on the newest nvidia drivers, I dropped down to 398.36 driver and things feel smoother.
For maximum tweaking, create these custom rez:
1080×1200 (oculus native)
1296×1440 (1.2x)
1512×1680 (1.4x)Then you’ll have to do repeated restarts to tweak up the FOV, but a zoom control lets you know which direction to go at least. Those are 9:10 aspect ratio. Start at 96deg vertical, and work down from there.
If you use opentrack, don’t disable headtracking in vorpX, just set the sensitivity to 0, and turn off roll/translation. That way you can still look around in edgepeak mode.
