You would do that at hardware + driver level for it to be reliable. So many things need to be added like head-tracking, stereoscopic rendering just for displaying things in VR (not even speaking of stuff like motion controls here)
So it's really up to companies like nVidia implement, similar to how they did Ansel. For whatever reason they don't seem interested. 
In the meanwhile software based hacks like VorpX is the best we'll gonna get.
