v23 PTC PC Software Release Notes

[ShowbizDonkey]

Quick note on release numbering - v22 was an internal only build, so we're jumping to v23!

Oculus Rift S

• We resolved an issue in Oculus Dash where pinned windows would show graphic distortion across the entire pane and not be visible to the user.

Oculus Link

• Increased encode resolution which improves visual quality while running Link.

Another thing that just baffling me is why they felt the need to encode video for Link, correct me if I'm wrong, but ATM I have two 4k monitors connected via single USB-C port with HDMI adapters to my macbook pro at my job and it works just fine and I don't think that there's any encoding going on there. So they have usb-c on Quest - why not just send uncompressed video signal through? As there's "ALT mode HDMI" released in 2016 it certainly possible (well maybe there's resolution to consider, but anyway the point stands). But I'm not pro in such things so this is just speculation, never mind that 🙂

On Mac and capable PC, the USB-C port can be used as Thunderbolt port.
Thunderbolt port are capable to drive digital video signal like HDMI or DP.
This is not the case for Quest 1/2.
Moreover the XR2 SOC has a direct bus connection to the LCD panel driver, witch means that to drive that panel by an external connection like HDMI or DP, need an extra circuit switcher, that indeed is not so simple and increase costs.

Yeah, I've read requirements for 4k/90Hz video and it looks like Oculus is right with encoding, as direct video would require > 10Gbps, so I was wrong in that regard. Well the question is - can they increase encoding rate further or 500Mbps would be really enough, especially when encoding width will be fixed (if it's really a bug and not intended behavior, later would be pretty sad cause ~2300 really not enough).

I guess the easiest thing to do is wait until your Q2 is also on v23.  Plus, don't push any performance updates, esp. 90hz on your PC v23 app until you get this. Probably best to select 72hz for now. There are lots of people using a mix right now but most can find a way to make it work temporarily.  It's a pity that a major rollout like v23 cannot be rolled out a lot quicker imho.

Also, since you posted this on the v23 PTC thread it's not clear if you even have v23 final.  If not, you mayu want to roll out of beta and try again.  Good luck mate.
