Sudden Poor Performance in Link

Both my QPro and Q3 headset got the non-PTC v201 update earlier today.  My meta-link PC app got a non-PTC v85 update a couple of days ago.  I don't see any significant ui changes, nor do I see the navigator feature.  At least both headsets now startup properly.  Prior to this update I needed to press my power button twice in order for it to startup the Quest home.  Otherwise, all seems to be working fine with my QPro using Link and Q3 using Air Link.

I did notice that if I use Link (official link cable, 9800x3d/rtx5090) with Fixed Bitrates there seems to be an upper limit of ~650-700mbps (still looks very good, to me anyway). 

I normally use dynamic bitrates and in this case there isn't any limitation, and worked fine with up to 960mbps, but it does start to add latency much above ~800mbps.  TBH I can't see any significant differences above 700-750mbps, and this doesn't add any appreciable latency.  So, I'm sticking with dynamic bitrates enabled and 750mbps Max.  I checked all this out using the ODT hud/performance/link details btw.

If you haven't tried dynamic bitrates for a while, I suggest you try them out.  With ODT link settings I enable dynamic bitrate and use 750mbps Max dynamic bitrate.  The beauty of this is that I can use the same ODT for both Link and Air Link. 

With Link I'm seeing a pretty constant 730-750mbps and with Air Link I'm seeing a pretty constant 200-230mbps.  Obviously, there is some graphical noise, but these usually settle down after 5-10 seconds.  The main thing is that overall, I'm getting very good, stutter-free performance.  I currently set meta-link graphics to 80Hz refresh rate with res slider full right.  Depending on the app, I often add 1.2-1.4x pixel density and also mod ASW modes (eg. Forced 45fps, actually = 1/2 your refresh rate, asw off with msfs2020/2024).  I still use the good old Oculus Tray Tool game profiles to do this.  Although, it's pretty easy to just edit ODT directly and most of these can be done on the fly.
