PICO 4 - My test is over, here are the results

Sure. For starters I’m running a 4090 and a 5800x3D, Win 10. MSFS on DLSS Quality in most areas, balanced if I need to in others, mixture of Ultra, High with some at Medium. No MP, or live traffic, airport vehicles etc fairly low. New Asus Wifi 6 Router.

Just noticed that for some reason today I can’t set streaming bitrate higher than 131 Mbs, no idea why that is but game still runs fine.

Thanks a lot! Similar setup to mine. I ordered an Asus RT-AX55 1800, which one do you have?

The Bitrate thing seems so random. I’m currently on a dedicated wifi5 with 866mbps max data rate. Yesterday for a while I couldn’t go above 86 bitrate, then later it just stayed at 150 the whole time.

And now you with a better router can’t get past 121, how is that possible?

But yeah, your settings seem similar to mine but I wasn’t happy with the clarity/compression artifacts at all.

What FPS are you getting without SSW? It’s better than WMR repro but I still don’t like the artifacts, which are still quite noticeable.

You must increase the resolution in the OpenXR Toolkit, not in SteamVR. Try that, play with the sharpness options and you’ll get your details.

No problemo.

I went with the Asus RT-AX55 too.

The variable bitrate was because I had selected auto adjust bitrate on the Windows VD Streamer App. With that set to off (which they don’t recommend) you can select the maximum 150Mbs for VR streaming. With it on, it depends on what connection speed your router is providing when you fire up VD it seems. I had my Asus Router on the floor just now and it knocked the connection speed down to 800Mbs or so. Up on my desk it mostly gets 1080 to 1200Mbs. I get very few stutters using WiFi 6 in MSFS.

I can get up to 90fps at times in rural areas in GA planes without SSW, but it dips and climbs a lot. I find SSW so much better than MR on WMR that I just leave it on and forget about it.

As for clarity, are you using NIS? I found that going from CAS in the Toolkit to using NIS for sharpening worked better. Things got a lot clearer with my current sharpening settings in VD and the Toolkit.

Ah, that explains it, thank you. It would seem i made a terminal error buying a 3080 ti in september 22 as it’s just not powerful enough for pico. As far as VR goes for me, i have definitely drawn the line with WMR. I’m not supporting something that’s clinically dead. I also just got fed up with constant tinkering. There were moments where i have achieved perfect smootheness and clarity with the G2, but then one update or the other messed things up again. I am probably going to stay away from VR until something tethered comes along and has a normal price tag. Pico 4 if tethered would have been a very good g2 upgrade, i’m really sad to see the market is going all in on wireless. I’ll upgrade my computer when rtx 5xxx series drops. i suppose that should finally be strong enough to run msfs at max :smiley:

What combination of Steam and Toolkit resolutions would you suggest?

I briefly tried that but for some reason Toolkit wouldn’t let me go above 3400x3400 or so

No I was using CAS, will try NIS, thanks

Can anyone explain the relationship of the bitrate and the overall data rate? If the max bitrate is only 150mbps, why is it important to have the full 1200mbps if possible? Isn’t the requirement just a fraction of this total potential throughput?

I guess there is some overheard for VD itself, audio, control inputs etc. but the difference still seems extreme. Yet everyone on forums etc. says 1200mbps is much better than 866, wifi6 much preferred to wifi5 etc. How can this be?

You can leave SteamVR at 192%

Then you can upscale in the OpenXR Toolkit. I’m using 4468x4468 right now.

To do that you have to modify a registry key, because SteamVR has a bug and it caps at 3240x3240:

HKEY_CURRENT_USER\Software\OpenXR-Toolkit\MSFS\resolution_width

Insert the value you want. Then ALT-TAB to confirm, and close. You will see the number in the tool, but don’t modify it there, or the bug will reactivate and you’ll be back to 3240 - and you’ll have to re-modify the key.

(The next version of the Toolkit shoud fix this “issue”).

I’ve wondered this very question myself lately, even more so when it comes to an Oculus Quest 2 and the official link cable. An Oculus speed test on the cable achieves 2.5Gbps. But the max bit rate that can be set in the debug tool for the headset is 500Mbps.

Airlink on the Quest 2 only uses up to 200Mbps, regardless of the wifi connection speed. The 5GHz channel of my network is capable of 866Mbps.

In Virtual Desktop, my limit is capped at 150Mbps.

I too am curious to learn more about this topic.

Cheers,

open xr at 200 with dlss quality and cas sharpening is amazing. I run this so smooth with an 4090.
I also read all the wow experiences thks for sharing. saves me the trouble…

On the G2 I assume? Yeah it looks pretty great, the colors are a joke compared to the Pico though. And the G2 never stays smooth, sooner or later there are some stutters, which don’t show up in the frame times at all, so it must be WMR related.

This has frustrated me so much over the last months that I just wanted to try something else. I’m now convinced of what I suspected: my system can run it basically butter smooth but WMR was messing it up.

Still not sure whether I’ll make the switch completely though, need to keep dialing around for a while.

just out of curiosity. Did you sell your G2 yet? And do you per chance have a V2. I have to say i’m a bit sorry i sold it, since no other viable option exists for me and i am now thinking of buying a used one. If you have a V2 and would be interested in selling it…

Not sold it and not currently looking to sell it, sorry!

Thanks, these settings really help a lot!

Unfortunately now I’m in a situation where I have better image quality but can’t quite reach a consistent 72fps without degrading it again. Also partially because I’m main thread limited in many context just below 72.

At the same time, I can’t do the “lock to 45 fps” (with 90hz) that always worked really well for me on the G2, because for some reason 45fps on the Pico seems super stuttery, completely different than on the G2. On the G2, 45fps was a magic number, was super smooth (apart from the irregular stuttery phases now and again).

There’s always something lol.. But I definitely see the potential. With another hardware generation (maybe even the next x3D chip will be enough), locking to 72fps at acceptable quality should be possible. I wish SSW didn’t look so bad to me.

@BearsAreCool510 45 fps seems stuttery likely because it is not an even divisor of 72 hz..

45 worked on the G2 as its native refresh is 90 hz. The sim is looking for a 1:2 or 1:3 ratio to sync up to. Try 36 fps if running in 72 hz mode.

As I said in the post, it was of course set to 90hz when I locked to 45!

@BearsAreCool510 Ah sorry, misunderstood. Not enough sleep! hehe.

I am genuinely curious to see if they eventually add a displayport capable version of this headset at some point. That would really take a lot of the layers out of the equation.

Cheers.

Yeah that would be amazing.

Although I feel like there is a much more visible screen door effect than on the G2, although maybe that’s just an illusion and down to compression.

Also pretty bad mura and glare. The latter only when it’s dark. Everyone raved about how it’s “no God rays”, but this is equally bad

After some more messing around:
I can get 72fps more or less locked (without SSW of course) in more rural areas with DLSS Performance. In Tokyo, it took Ultra Performance, and still with some dips. Both in combination with 192% Steam VR and 4468x4468 in Toolkit res override.

Pretty ugly picture, but the motion is amazing! This motion with the G2’s (or I guess Aero’s) sharpness but also the pancake lens clarity would basically be perfection.

What’s strange: When I move to DLSS Balanced or Quality, it’s not the GPU that’s preventing me from hitting 72fps, it’s the mainthread and sometimes the rdrthread. I find this confusing since I thought this would all be GPU load. Does anyone know whether higher DLSS quality levels usually increase CPU load too? They definitely do here.

In any case, will be interesting whether a 7800x3D can improve things when it launches next month (currently on 7700x).

One annoying thing I’ve noticed is that changing the DLSS quality level while in Pico VR can cause steam VR to crash, anyone else had this?
