It was released a couple weeks ago. Saw it in a post. It didn’t show it as an update in MS Store for me, so I redownloaded it to force the update.
Saw in some post somewhere else that setting 2D monitor to 60 hz helped. Worth a shot. Seemed to help me but this tweaking is so random with all the bugs in MSFS, WMR, nvidia drivers, etc, that it’s hard to tell what changed what. Just thought it might be worth a shot for you too.
