SteamVR lag & stuttering
-
Running any game in 3D non VR is butter smooth.
Running Virtual Desktop in Pico4 runs smooth as well.
But since this week when I start SteamVR, it’s choppy. Stuttering, lagging, frame drops…3 screenshots during a dogfight session in BMS, moving my head from left to right I’m getting major latency & frame drops.
Any idea what is going on?Any idea what’s causing this? I’ve tried about all fixes I could find in Google but none seem to work.
PC specs:
- CPU: AMD Ryzen 7 7800X3D
- MoBo: X670 gamin x AX
- GPU: MSI GeForce RTX 4080 16GB Ventus 3X OC D6X
- SSD: Samsung 980 Pro 2 2TB
- RAM: G.Skill 64 GB DDR5-6000 Trident
- VR: Pico4
All drivers are up-to-date;
Pico connected via dedicated router & switch with like thisNVidia settings:
- all default except
- set to max performance where possible
- prerendervr frames: 1
BMS settings:
- latest version,
- all set to max,
- I’m getting over 400FPS in regular 3D and was getting solid stable 90FPS in VR up till last week. So doubt it’s BMS related.
Virtual Desktop settings
- fixed bitrate 100MBPS (performance overlay says I can have 130)
- Godlike graphics
- 90FPS (also tried 72 fps but no difference)
SteamVR settings (tried original latest version and now latest beta version)
- 100% image resolution
Other settings:
- Steam processes set to higher priority
- Audio only send to headset

Maybe it’s due to last SteamVR version 2.0 release?

IIRC it was released last weekend.
Just my two cents
-
@oleuzop hmm, could be. Let’s hope a new update comes soon so I can rule that out or find out it’s fixed.
-
Are you running SteamVR Beta update? If not, give it a go, just go to Properties/Beta in Steam Library…
-
@Icer yes already running that

Think I found it.
Looking back at my screenshots I noticed the 5GHz- 130Mbps next to the wifi logo. It used to say a lot higher Mbps. So I pulled out the entire usb-c to ethernet adapter and noticed VD was still working in the settings as in the screenshot.
So I’m guessing the entire adapter is broken and it switched back to wifi instead of actual ethernet connection/speeds; as wifi isn’t the best around here, that might be giving insufficient bitrates while the fixed 100Mbs setting is then having issues. -
Latest version of of steam vr launched this week as well. Perhaps that’s the culprit?

Ordered & tested a new adapter and now power & signal are coming through. Solid 90 FPS without budging. Happy camper.

It seems like version 4 will comes with OpenXR implementation and that will increase some fps without steamVR layer
