What type of rendering are you using? DLSS for example will make the gauges fuzzy.

124

Use TAA… with DLSS you’ll need to push the resolution…

125

I have tried both TAA and DLSS Quality. Neither bring my Pico 4 to the level of My Brother’s images with an near identical hardware 5800X3D for me, he has 7900X3D, the rest is same 4090 etc. Virtual desktop Pico 4 hardware and FW etc. In game same setting etc…
I’m at a loss. I feel SteamVR is picking up or not something essential to provide a comparable image.

126

I have used Toolkit on TAA at 4400 overide and DLSS all the way past 6600 overide and it’s still not crisp. Steam Per Eye from 2100 up 3120-400% 5404 and 500%. I see improvements but not crisp. Plus Major Motion reprojection artifacts at any Setting.
My Brother and I have compared screenshots and it’s just worse. His game is installed on Steam, mine is Xbox game pass.

127

Maybe Asobo silently degrades textures on gamepass :smiley:

128

and introduce Motion reprojection artifacts?

129

Well I installed the steam copy of the game and Pico 4 handles it exactly the same as the MS Store or Game Pass for PC version. Fuzzy. Motion artifacts and general softness compared to G2. The sweet spot is big but soft. Given MSFS plentiful edges in cockpits, this could be the deal breaker. Looking at other games it is solid and works well but for MSFS it is trumped by the G2 for picture quality and performance with WMR and OpenXR native solutions. The Motion reprojection in WMR or Toolkit is better in my opinion.

If you are coming from WMR there is a possibility that you are hitting the SteamVR resolution bug.

  1. close SteamVR entirely
  2. locate the SteamVR settings file, it’s somewhere like C:\Program Files (x86)\Steam\config\steamvr.vrsettings
  3. in that file, search for maxRecommendedResolution and make sure it’s set to very high like 8192 or 16384.

If you were victim of that bug, then in step 3) you should see a value of 3240. That would have constantly capped your resolution.

Pico4 so could the “fuzzy” be down to compression?

I had one before my pimax crystal, using usb_c.to ethernet was far less compressed (compared to either usb tethered or WiFi) but still the compression introduced a softness/fuzziness…
(Edit: despite having a 4090 and using godlike mode on vd)

Loved the pico4 in a lot of ways (comfort/size/weight) but the image quality on the crystal is soooo much better

Matthieu, Vous etes un Dieu! 3240 etait le max. Tout est resolu!

You’re a gift to this community like you can’t imagine! I know, French modesty etc etc… I lived in france for 7 years…
Thank you.

Thankyou,man that sorted it.

What did you set your resolution to in:

  • OpenXR toolkit
  • SteamVR

I did have the 3240 resolution set in the steamvr.vrsettings.

135

I had huge issues using SteamVR resolutions above 3120x3120. 100% then used toolkit at 4320X4320 all the way to 5300x5300. It is capable on 4090. So my SteamVR 3120x3210 100% then dial in toolkit. 4320x4320 without FFR, and you can tweak up from there with FFR quality wide or specific tweaks to run 5000x5000 up to 5300. Go slow there because you can totally blow things up and end up in reboot and such to regain control.

136

if you had the SteamVR 3240 bug then your pico will look fuzzy. you got to look up Bucchia’s comment to increase that number to get the headset to respond.

137

Sounds good will try that and let you know how it goes.

138

Tried it and upping the resolution in openxr definitely shows an improvement now. Thank you for the help. Now going to try the VirtualDesktop openxr that Mathieu just released.

139

I found if you changed the value 3240 to 8192 or 16384 in the file of steamvr.vrsetting . the number will not stay. When you re-launch steamVR the changed figure will go back to 3240.

140

Correct. It does seem to reset it.

141

So Pico 4 users. Im back, will return my Q3 tomorrow. Pico 4 outperforms it with the latest VD-OXR runtime .

If you have 4090, you must try these settings: First go to OpenXR toolkits discord server: OpenXR Toolkit (NO OPENCOMPOSITE SUPPORT) And #oculus-technical and see pinned post and download VirtualDesktop-OpenXR-0.6.0.msi . Then go: Home · mbucchia/VirtualDesktop-OpenXR Wiki · GitHub You will see, what is going on. It is VD-OXR runtime made by legendary @mbucchia. And it works great! You dont need steamVR anymore. This is a game changer for sure! Remember to de-activate virtual desktop as a addon in SteamVR. And be sure, that Virtual desktop is active runtime with xr-picker software. So launch MSFS, launch VD.

Virtual Desktop settings

  • 72fps
  • HEVC 10bit
  • Bitrate 120
  • Sharpening 70%
  • Buffering ON
  • SSW disabled

OpenXR toolkit settings

  • Forfeated rendering: quality - balanced
  • Turbo Mode: ON
  • Override resolution 3900 x 3900

MSFS Settings

  • DLSS with quality

EXTRA : swap msfs dlss 2.4.1 to newest 3.5.0. 1) go to Microsoft flight simulator folder and locate nvngx_dlss.dll 2) copy paste it so it will make backup to same folder 3) download this NVIDIA DLSS DLL 3.5.0 Download | TechPowerUp 4) copy and replace nvngx_dlss.dll 5) now msfs dlss 2.4.1 is updated to 3.5.0 It could be placebo, but i think it is 20% improvement with cockpit sharpness. If you have lower specs GPU, just lower resolution override from OXR toolkit or disable it. When you hit 72fps with 72hz mode, you will get it. Trust me. Exact same constant fps with matched hz is every flightsimmers wet dream.

Thanks for this - will be trying out this weekend.
