dont know about native support, is steamvr playable?
or did you get osvr working with ED in SBS mode inc head and motion tracking?
how does it compare to the e2?
need to do further testing with various core/steamvr-plugins, but i can already say that
steamvr is working, playable, BUT positional tracking is 'jumpy', to say the least.
some claim they have it working, but all of their solutions did not work for me.
seems to be a known issue, note that osvr-steamvr-plugin is just in alpha state.
the whole thing clearly is a work in progress, and i wouldn't recommend it to a casual gamer.
techie-types will like it, though. image quality is clearly better than a dk2/deepoon.
fov is a bit low, 100°, but i saw them working on ultra-wide lenses, 150°, no eta as of today.
sure as heck will get them.
will report further findings.
