It's interesting the micro stutters that are reported by MANY players in game, and I experience them myself.  I Play with a meta Quest 3 VR headset, and since the changes, I've had a problem of the frame rates dropping to 18, and bouncing up to 35 fps, from a usual 72 fps. I know that Meta has released a few updates as has Microsoft, but the ubiquity of the experience is what concerns me.  I've found it happens after i've been on a while, and if I log out of the game and restart it, it will usually fix for a while.  Also the pilot micromesh keeps coming up occasionally without me making changes.  I'll trouble shoot my own rig soon, I have been fairly apathetic of late, but will get to it soon.  I haven't broken out my route tracing software to see if the link is the issue, but that will likely be something I end up doing.  Hopefully Hitech is looking into it, and will let us know what the deal is for the widespread microfreezes.
