No more Dynamic Bitrates with 2.9 final update using link cable

Both my 4yo QPro and 3yo Q3/512Gb headset updated yesterday to the final (non-beta) 2.9 update.  First thing I noticed was that my graphics were pretty soft/blurry with my QPro using the official link cable.  After investigating this I found that the problem was that after the latest update my Link cable dynamic bitrate was limited to only 200mbps. 

I had been successfully using 750mbps max dynamic bitrate (which usually gave me 730-750mbps) since around the v74 update.  I really liked that because it worked well and also allowed me to use the same ODT file for both Link and Air Link (which would usually end up at ~200-230mbps).

The simple workaround was to just go back to Fixed Bitrates when using a link cable.  I’m currently using 750mbps fixed, and this is working well.  Only complaint is that I now need to remember to change this from 750 to 0 (zero) prior to running Air Link (which still works the same with dynamic bitrates).

I have filed a bug report on this.  Cheers mates.
