A bit of a nice surprise, as a new OpenXR version arrived in preview. The big change in this one, and why it’s worth looking at, is that they have some new reprojection modes for sims struggling to maintain headset framerates (stares for an uncomfortably long time at MSFS VR until it can’t stand it anymore and has to look away in shame).
Just go to the Microsoft Store app in Win10, click the … next to your Avatar on the top right and use ‘Downloads and update’. That’ll grab latest. If you don’t have it, you can get it here:
The new Motion Reprojection now works at 1/4 framerate, so (fairly incredibly) you can get a headset working at 90Hz, but the sim only needs to pump out a framerate of 22.5 FPS. (Now switches stare to DCS and its lack of OpenXR, but it just ignores me and smiles happily back obliviously).
You need to opt-in to the 1.6.2104 version using the ‘Use latest preview OpenXR runtime’ and turn on Motion Reprojection (you can try Automatic as well, that works but can be a bit juddery when changing mode), like here:
I’m finding that this new update is great. You obviously have to put up with reprojection artifacts sometimes, but for a civil sim or just tourism flying, it works nicely.
