My Vive Pro 2 is suffering the same issue with Windows 11.
Reverb G2 and Index are fine, Vive Pro 2 is a complete suttering mess.
Too far along in Windows 11 for me to roll back. It has been reported to HTC but don’t think they are going to be in any hurry too do anything about it unfortunately.
Thankfully my Reverb G2 is not affected and it is the headset of choice for me with MSFS 2020 due to using Open XR along with Open XR Developer Tools. Sure would like to have my Vive Pro 2 working for some of my other games though. I am not a happy camper with HTC right now.
