Dynamic Bitrates with Link and Air Link - a Dynamic Duo!

Since V72 update (fortunately, not the bricking one, lol!) I've found that dynamic bitrates work very well with both Link and Air Link.  I've also found that h.265 (hevc) works very well with Link, better colors/contrast than its default h.264.

If you set the Oculus Debug Tool (ODT) as I'll try to show now (not sure if I can copy/paste my ODT settings, first time I've tried this using windows snip btw) then you can use the same ODT for both Link and Air Link.

The main thing is you set the slice encoding = off, enable encode dynamic bitrate, and set the dynamic bitrate max to 900mbps.  Really doesn't matter how high you set this because the dynamic thing will only go so high anyway.  I set it to 900mbps because this was the highest I could ever get to work ok with Link/h.264.

Anyway, I thought I'd pass this on because its been a real improvement for both Link and Air Link, for me anyway.  Cheers.

Thanks @TomCgcmfc , I’ve been a bit lazy digging into these settings as the default has always seemed so good but I should definitely test these tweaks

Ok, hopefully last update on all this, lol!

After lots of experimenting with both my QPro and Q3 headsets I’ve come to conclude that overall I get better distance clarity using Link with its default h.264 codec. So I’ve revised my ODT base settings as follows (hopefully my cut/paste will work). For msfs 2020 I add 1.40 pixel density (really sharpens up cockpit instruments using dlss/balanced) and I’m using asw mode = 45fps forced, asw disabled (using 80Hz refresh rate this gives me a very smooth 40fps).

Again, by default, Air Link still uses h.265 and encoding slicing = off, Link uses h.264 with encoding slicing = on. This ODT works fine with both Air Link and Link. I’m also now finding that DX12 with msfs2020 works a bit better now (HAGS still disabled).

Hope some will find this useful.  Cheers.
