Pico 4 out soon?

Mr_Sukebe said:
Overall, it has a lot of promise, but feels unfinished. e.g. why are the streaming limitations so low via VD and the Streaming Assistant. The USB connection "should" be able to support upto 10Gbps, so why does it appear to be capped at 120Mbps?

This is a direct reply to Mr_Sukebe but, also replying to people earlier in this thread who were wondering about wifi 5 or wifi 6 and USB connection etc.

In any headset that relies on Streaming over USB/Wireless, the limiting factor is usually the decoder on the headset. The information is encoded on your computer and sent to the headset via USB or Wireless, then decoded and displayed. The decoder can only handle so much info at a time, doesn't matter how much bandwidth you have.

First wireless. If you are using a router as dedicated access point for the Pico 4/Quest 2, then there will be no difference between a Wifi 6 router and a Wifi 5 router. The reason why GGodin, the Virtual Desktop developer, recommends Wifi 6 routers is that they might be better where the router is the home router and might not be in the same room as the where you are using the headset. The problems with some of the routers that are supplied by ISPs is that the don't have the best Wifi or might not have the best CPU for handling constant streams of data. However, the biggest issues with ISP provided routers is that they sometimes don't have gigabit LAN ports. If you don't have a gigabit connection between your computer and the router that the headset connects to, you won't have a great experience.

USB connection: A USB connection should be better than Wifi. I would say that getting PCVR up and running wasn't a high Priority for Bytedance with the Pico 4. When/if they update the software the USB connection should improve a lot.
 
In theory, if the pico 4 xr2 chip is running faster than the q2, then it should be able to decode faster and produce better results I'd guess.

I think either someone here, or maybe reddit, mentioned that HVEC recently updated their codec. I've switched back to it and the improvement in clarity in my Q2 as well, is massive.

I would say not. Don't know too much about the Xr2, but I would be very surprised if the decoding wasn't handled by a separate chip.

It does look better in virtual destop than it does wired, which is odd, even on my crappy EE router,

I tried your settings as well but so far I've been unable to make it look as good it does on quest 2 Let alone a G2

Hi Just-Dave, Aren't you using the USB connection on your Quest 2? If I am remembering correctly?

Is your PC connected to the router wirelessly?

Looking at getting my son a VR headset for his 11th birthday, anyone tried theirs on a similarly aged child?

My boy is 10, and small, has used my headset since he was 9. It's not a perfect fit, but it's good enough for him to enjoy himself. Don't let him do any online multiplayer stuff, but he's enjoyed Puzzling places, walkabout mini golf and beat saber.

q2 by the way, with the default strap.

The h264 and hevc decoding will be done by special instruction sets within the xr2 chip. Hevc at 150mb is like 500mb on h264. The bitrate is plenty, the issue is with latency. The higher the bitrate, the more pixels needs to be decoded inside the xr2. This is why an extra 50mb causes +5-10mb latency. 100mb hevc looks really good, so not an issue, not as good as a displayport cable, but I would argue hevc over wireless with virtual desktop is BETTER than h264 through a usb cable. The bandwidth is small enough that you don't need to use a usb cable, even for quality and/or latency. This is why VD won't support usb cables, you don't need it when being forced to use encoding.

Next step (for encoding) is av1 (30% more efficient than hevc) which is coming with the new 7000 series AMD cards, and also on the next qualcomm soc. Still, I don't like encoding as prefer to plug into a graphics card, but for wireless it's going to be pretty great.

Sigh.....really can't wait for deckard.
 
Some good comments guys, my thanks for advising ref the data requirements for HEVC and similar.

Managed to get a refund from Steam on the VD purchase, so that's cool.


What I've not been able to do is get "Mixed reality portal" to recognise that the Pico is actually connected up. No idea what's causing that, but it's resulting in OpenXR not loading.
Anyone else had this?

I'm sure I read that at the minute OpenXR is not compatible. I know when I try and use it in iRacing, it sits there for a while before changing itself to OpenVR.

Cheers, have ordered the 256GB Pico 4 so hopefully it will be OK for him.
 
OK, mine's going back.
- No OpenXR
- The visuals with the Pico supplied Streaming Assistant really aren't that much better than I get with the existing Rift S
- Virtual Display gives a good display, but I can't get around the amount of lag spikes that I'm suffering. That "might" be resolved with a local wifi dongle
- I just haven't case a use case for the standalone capabilities. I have taken another look at the list of games for standalone, and none of them really appeal

Guess I'll wait for the pancake PCVR headset with a DV port, that doesn't have the cable design of the G2

Yes pal,
I use quest 2 wired,
And tried pico wired and with VD,
My experience is the quest 2 beats this by some way visually,
Granted I've only had chance to play automobilista 2 for a few hours yesterday, my my opinion is based off one game, other games may differ

The Pico wired isn't good yet.
