Quest 2 Virtual Desktop Performance Thread

Been playing around again and have noticed that with my nvidia card H264 and sliced encoding off got rid of a lot of the micro stutters I was getting with VD. Also got a bit of a speed boost downstairs after getting rid of the huge old, ugly, dangly metal light fitting that I broke playing Alyx for a low profile led thing.
 
There is more to it than that I think. I have an onboard Atheros thing and nothing prevents me from creating a 5GHz hotspot but like Snougar it was limited (300mbps for me on both the Quest 2 and my phone, which is a suspiciously 2.4GHz-like speed but both devices said they're connected at 5GHz).

In theory a solid 300mbps should be enough but it wasn't. Actual performance must have been 10-20% of the reported connection rate.

No, there is no more to it than that. That's the exact limitation that I was talking about. When you setup a hotspot in windows 10, it either limits you to 2.4Ghz or it will work at 5Ghz but at 2.4Ghz speeds.

And, It's not just connecting your phone to the hotspot that fools it. It's how you create the hotspot. You have to connect your wireless adapter to a 5Ghz network, then create the hotspot and then connect your mobile to that hotspot.

What did work for me was taking down one of my Ubiquiti AC Pros, putting it in the same room, plugging my PC straight into it, and then using Ubiquiti's Wireless Uplink (basically meshing) to wirelessly connect the AP back to another AP still wired to the main network for internet access, i.e. turn the AP into an over the top "ethernet-WiFi bridge / hotspot dongle".

You would think adding an extra hop would add latency but it actually reduced it. Pinging the gateway averages <1ms whereas using my mobo's WiFi it was 2-4ms with random spikes. Presumably proper APs are just better at WiFi than onboard or USB.

Basically you just setup one of your AC Pros as an Access point for the Quest 2. Which is the recommended way to do it. And, yes, a proper router/access point is better because they are designed for that exact job. YMMV when you are using a USB or Wifi Adapter as Windows is managing the hotspot.

Did you makes changes to the settings in Virtual desktop at the same time as removing the huge old dangly metal light fitting?? If so, I wonder was the light fitting the problem and not the settings in Virtual desktop? :p

Seriously, yeah, you should experiment with the settings in Virtual desktop and find the best configuration that works for you.

Nope, two different days :)
The huge dangly, metal light fitting was directly between where I was trying to play and the router upstairs. Replacing it with a thin bit of tin and plastic has got me a small but consistent boost in connection speed (about 100mbs).

That's literally what I did and it didn't work for me.

PC connected to 5GHz with a 2x2 80MHz PHY rate of 866Mbps. Create a 5GHz hotspot and all clients connect at 5GHz (as reported by Android and the Q2) with a 300Mbps PHY rate ... which makes little sense as it matches no 5GHz rates but does match 2x2 40MHz on 2.4GHz so it's probably some driver bug. Snougar's reported 200Mbps makes more sense as it matches 1x1 40MHz on 5GHz.

Google around and you'll find many people with same problems and all sorts of weird workarounds (the most common of which is connecting a phone before the Q2 somehow kicks the rate for both up to 866Mbps), none of which worked for me. The fact that upgrading the drivers then explicitly blocked 5GHz hotspots outright makes me believe it's the drivers that need to be "fooled" rather than Windows so the solution is going to depend on your device which will be why most people are recommending not wasting too much time on it.

From what I gathered it's something to do with 5GHz not being completely unlicensed in every country. So different drivers might be targeting different regions, the lowest common denominator, disabling 5GHz all together, or you may be lucky and have region options in your device's driver settings (my onboard thing has practically no settings).

So I finally got my pc wired up to router. Airlink on. Menu runs smooth but can't launch steamvr. I get the 'steamvr failed to initialise....." error.

Few reddit posts about this but no solutions. Oddly link works fine.

Anyone else had this?

Edit: found a work around. Pressing the left oculus button when the steam purple net screen is stuck let's you pick and load the steam games successfully.

Tried airlink and it works but its looks like 360p with variable bitrate, when i try and set a fixed bitrate in the settings 100mbs is the highest you can choose and it looks brilliant but its unusable on that setting, My pc is running on a usb wifi dongle and bt smart hub, i'm not close enough to the bt hub to run a ethernet cable, what's the best thing to try next?

Sorry if you've already posted it, but what's your processor and graphics card?

It doesn't work with a wifi connection between your PC and Router. It's way too slow that way. I would look into setting up a hotspot on your PC using the USB wifi dongle and connecting the Quest 2 to it. The problem is that a hotspot on windows 10 can sometimes be total faff to setup and not work even when it's setup.

If you try to set it up and can't post here. Can give you some things to try.

Just tried setting up windows 10 as a hotspot and its a lot better! Thanks for this tip! I tried going straight in at100mbs off the bat and it was still super laggy just browsing the desktop, tried 40mbps and its smooth and looks a lot better than before but still not quite what i had hoped, will have a play about now and see if i can improve it, feeling hopeful about this now. will be awesome to get a great picture using wireless.

It sounds like your hotspot is running at 2.4Ghz speeds, or is running at 2.4Ghz. Can you check if it's running at 5Ghz?

If it is running at 5Ghz, then you should try this. Disconnect the Quest 2 from the hotspot. Then connect your phone to the hotspot. Now connect your Quest 2.
You will have to do this each time to trick windows to run the hotspot at full speed.

It says its running at 5ghz, leaving it on dynamic looks a lot better than before but it seems a little inconsistent sometimes i get pretty bad lag for around 20 seconds then its fine again, happens in basic games like plank experience not just in more demanding games like half life. still can't get it smooth on anything above 40mbs, not sure what other people are running at.
 
If i were to buy a dedicated router for airlink would i still be able to use my original wifi dongle for internet access while connected to the router at the same time? not even sure if that will makes sense to anybody reading lol. Basically my current bt hub is too far away to run a direct Ethernet cable, if i were to buy another router and connect it to my pc via ethernet, it would have no internet connection but im thinking i could just use it for airlink, if i were to do that would my wifi dongle still work as normal or can i only connect to one at at time?

One question I forgot to ask, what make and model is your Wifi Dongle?

Have you consider power line adapters? Have you got good wiring in your house?

Hmmm not actually sure which dongle I'm using but it was a relatively cheap one from amazon supposedly 600mbs at 5ghz, Do you think its worth getting a better dongle? Not sure how good the wiring is in my house.
