I have a Pico 4 and have been playing around with Virtual Desktop settings to balance latency with visual quality.
The Decode time is often the single largest component of my latency: around 13-15ms at 150Mbps, dropping to around 8-9ms at 80Mbps. I have auto-bitrate turned off as it seemed to introduce slightly more latency and the connection seems stable regardless of bitrate. The default Virtual Desktop value was actually only 60Mbps.
So my question is: How much difference can you see between 80 Mbps and 150Mbps?
I can certainly see a huge decrease in quality once the bitrate gets down below 50Mbps, but between 80 and 150 i'm struggling to see a marked difference to be honest. I still see visible compression at 150, but i'm not convinced I see a lot more compression at 80.
I do see Quest Pro owners talking about 500Mbps+ bitrates though which makes me think I just am not doing a great job of spotting the difference!
I play at 90mbps on HEVC. There is diminishing returns going higher as the encoder choice largely dictates the overall quality ceiling that you'll see. Hopefully we'll see some big gains with Q3 as it is supposed to be compatible with the AV1 encoder which should give a big boost to quality so long as your GPU is compatible.
When people are talking about 500mbps they are likely refering to their settings for wired link rather than airlink / Virtual desktop
