Pico Connect wired with Pico 4 game render delay from head moving

[H@mer]

ISSUE
When I moving my head or look around, the game render tiny shaking or some delay.
I compare SteamVR Dashboard with Pico Dashboard to make sure it sticky together and not a latency problem or tracking problem.
It happed without open SteamVR Overlay that make that unplayable cause motion sickness.

Some games that i played have this issue such as Vail VR, Skydance's BEHEMOTH, Metro Awakening.
But not happen on Contractors and Contractors Showdown or Beat Saber, Pavlov VR.

I also tried an other streaming alternative ALVR-nightly and Virtual Desktop wired connection and yes it does not have the issue.
Why i don't use ALVR-nightly, because it has to many latency about 60ms+ but Pico Connect has only 15ms-25ms

This is video Pico Connect compare with ALVR.
Use Pico Dashboard as static point and if you observe carefully, you will see Pico Connect game behind SteamVR Overlay shaking a bit when i stopped moveing my head.

Ahh. So you guess that Pico Connect makes the lag, delays and stutters or jitters ?

See that ALVR makes really heavy lag. Mean the white borders left and right in your video if moving head sidewars. But you told that you know it makes high delays.
So, what you will do ?
You could try for testing a Beta of SteamVR. Beta temp_1.27.5.

It not feel like lag or fps drop because my fpsVR and XSOverlay on my wrist is steady.
Only game render it feel shaking.

Only Pico Connect has the issue not ALVR and Virtual Desktop
Best example is Vail VR, all UI is steady but not game world.
You can see that console text UI following to SteamVR Dashboard and game world is shaking same as other game i mentioned.

ALVR same as Virtual Desktop: https://streamable.com/f7xtb5

I can tell you that SteamVR Overlay, fpsVR, XSOverlay is normal and steady.

And yes i try all of SteamVR beta branch and downgrade Pico Connect and try Pico Streaming Assistant

Hmm.

What about your used hardware ? Pico 4 (PicoOS which version ??). Graficcard, Desktop-Operation-System ?
Framerate in games ? Refreshrate in the headset ?
Direct-Mode in SteamVR ?

Lasted Windows 11 24H2
Pico 4 5.11.2
13900k with RTX3090

My framerate is normal from my fpsVR Overlay 90fps around 40% GPS usage.
Most people in my discord community has this issue and said it SteamVR bug.

And i exact know it SteamVR bug because i try to test with cracked VR game using SteamVR and it patch StameVR made StameVR Overlay to old version (Before 2.0 update) and the issue is gone but i don't want to play cracked game i want to play my game from my library.

So you did say it. It is Steam itself. That was my fright because nobody of Valve believe that the Update 2.0 had broken all.
I got the problems with stuttering only since October 2023. The month when the Update 2.0 was released after a Beta-Testphase of only 1 week. Then the dummies pushed the new version into our world and the doomsday for VR-Gamers was alive.

What we can do is, using the old Beta temp_1.27.5 or accept that some games will stutter like hell.

Unfortunately, no any of beta branch fix my issue.

Wow. Today i got the same. Shaking on headsetmoving. Feels like a earthquake.
Wow, during i am writing that here my brain is total confused and that is the biggest touch of Motion Sickness i got in 4 years.

Never me was bad as now by Motion Sickness. Last Motion Sickness effect i got was in the first 2 weeks when i try VR the first times.

I am using a Beta now, Version 2.9.4.

And in my videos you can see that shaking also. A bit ... in the headset it´s much stronger.

Yes, it like a game's frame sync delay from head moving only game not other VR overlay this mean SteamVR has an issue.
And I just noticed that my non issue games has the issue after is open SteamVR Overlay while playing and after a three second it will gone (frame sync normally again).

And if you use a tool like FpsVR i can see that the usage of the CPU goes high.

Very sad is that Betas like 1.27.5 didn ´t help anymore. It is broken now also.
You told this issue some days before too.

What a mess with SteamVR.
Sure that i have no stutters or jitter if i am playing a game which is installed on my headset only. These apps are all optinized for standalone.
I am understand that is much harder to develop software for ALLLLLLL headsets worldwide.
And i wish the smoothness back which i could enjoy 2023. The age BEFORE SteamVR 2.0.

Only the Valve Devs know what the relation between the old and new SteamVR It is your turn now. *Make SteamVR great again !*

Update:

OPVR-Toolkit makes heavy stutters in Metro:Awakening and let the game crash when i try to load a savegame. Will test Metro with actual SteamVR and w/o that toolkit.

WOW !!!!

Change the Beta temp_1.27.5 back to SteamVR 2.8.8.
And i get SHAKING also.

The whole world ingame shakes if i move my head. Only a little bit but very annyoing.
ABD ... my GPU gets to hot. Normally when i play a game the GPU is around 55° warm, now with SteamCrap 2.8.8 it will reach more than 70° but the strange is the usage of the chip is much lower.
In Beta temp_1.25.7 the usage is above 90% the most time, in actual SteamVRcrap it is around 30%.

Ok, i learned it Valve !!!
Switch back to the GOOD but older version temp_1.27.5.

SteamVR beta participation: previous - The previous release
Best for me, no more shaking.

Thanks for that info. I will try that version. But when Steam is going to remove that version because the new updates we cannot use that fix continue. After the next update that actual crap-version will be the "previous".

Update: The actually "previous version" is 2.7.4. And i still get jitter. Seems that the tracking of headset and the controllers is not correctly and hangs sometimes on moving.

Also my GPU gets higher temps and the fans are crying like storms in autumn.
