Windows Mixed Reality (WMR) drivers have reprojection tech like ASW. It’s apparently meant to be pretty good, although I’ve not personally seen it work.
Tracking in the SO+ is meant to be better than the original SO, but the big difference between a Vive or Rift and this is that there are no external tracking cameras or base stations. The way it works is that the cameras on the headset (which are wide view, not just where you are looking) detect the hand controllers as IR dots. That coupled with sensors like gyro’s in the hand controllers provide placement info.
The upside is that you don’t have to run wires around your desk/play area, with the downside that sometimes physical occlusion will happen, or rather in English, your body will block the headset from seeing where your hand controllers are. For things like desktop sims, it’s all good, as you are probably using a HOTAS and not waving your arms around all the time, while for things like a stand-up archery game in VR (because you put your hands behind your head to fire a bow etc) then the Rift / Vive are probably better solutions.
The big unknown for me so far, and why I am waiting just a week or so, is to get some early reports on how clear the new panels are in the SO+ for things like X-Plane or DCS. The ‘anti Screen Door Effect (SDE)’ tech they are using is meant to be very good, but I have some doubts it will make things clearer or easier to read cockpit dials or MFDs. That’s the big unknown, in that it has the best resolution but this new tech for anti-SDE.
@BeachAV8R has one on order, so he’s the Impulsive Guinea Pig and will report back I imagine. Either that or leave it in the box like he did with the Rift for a week.
