OpenXR Update from Nov 17th - Reverb G2 CTD after switching to VR and back

If i have 45fps in certain high density area (mostly 50+ in mountains and country side) and i have capped fps to 45, will motion reprojection double my frames from 45 to 90? Or is it still tripling 30 to 90? Artifags are so annoying in some point, but in general motion reprojection is best solution for VR.
