Continuing the discussion from Holographicshell causing stuttering again in SU11 - VR with HP reverb G2, W11 22H2:
Latest Nvidia drivers from yesterday 526.98 (16/Nov) has fixed the stuttering issue (the holographicshell thing) ! now it runs butter smooth in VR ! 
Not on my system, unfortunately. I still have to kill the HolographicShell manually to get rid of the stutters:(
I noticed that the installation of Nvidia 526.98 - opened up the mixed reality portal - and finsished by requiring a reboot. was it the same for you?
Same OS and headset, nothing but stutters on 526.98. I rolled back
Same here. Unfortunatly I cant roll back to 22H1 beacause I had to do a full reinstall of Windows, MSFS did not start again after a CPU and MOBO change. Now I am lost in this… Windows 11 22H2 thing. I will have to wait for a fix.
