Technically that would work, but for a decent framerate you would have to use vorpX’s fast Z3D stereo method. For the better “true” Geometry 3D method your rig would be too slow in many games unfortunately, definitely in case of Skyrim SE, but probably also in case of Fallout NV.
I’m also not entirely sure whether the DK2 still works with the latest Oculus Home software, so please check that first. vorpX does not work anymore with the old 0.8 beta Oculus runtime.
