Hi Matthieu,
I can confirm: Turning off Optical Flow and addtionally set the registry key seems to bring back the old MR mode (seems to be the same as deselecting the OpenXR-Preview mode).
I also reset my Nvidia-Settings and deactivate MR and Upscaling in Toolkit to check all new modes (without reg-hack). We all have so many settings and combinations affecting VR, that it is difficult for each of us to find the best one the own system. And in addition simmers might have a different definition of what is his best look and feel.
Thank you very much for your outstanding support and also for the plan to implement an option for the old runtime (guess you mean the “Spatial processing” ). Who knows if a future update of MSFS or Windows breaks something at other places of the complex system.
For now, DXMV16S (using preview runtime but also using “ForceMotionVectorTemporalModel=0”)
