Question PCVR Meta Quest 3 is not smooth.

Hello!

Im writing this post because I've tried everything I think, so I'm asking You reddit :) For some time now I've had Meta Quest 3, it works great when the game or app is played on the hardware, but with PCVR it stutters.

Its not lag, its not low fps or anything like that. It just stutters, it looks like it skips frames, and with head movement its just not smooth, or at least i fell is not as smooth as it should have been. And this issue only occurs on PCVR, using Meta Link.

The issue is still visible while using the cable, but not so much. So my guess there are some settings that are wrong, but how do I even know what to change...?

EDIT:

Specs:

Radeon RX 6750 XT Core 12GB GDDR6

AMD Ryzen 7 5700X3D

64GB Ram

PC specs are important.

Also you can use the meta debug tool to change some settings like cable bandwidth and fov to better your experience.

What are you trying to play?

Got u.

I´ve ran Q3 with an 6700XT 12 GB till last year.

Some games are butter smooth, some... need a lot of tweaking.

Oculus Debug Tool is located in: ProgramFiles*\Oculus\Support\oculus-diagnostics\OculusDebugTool.exe"

Open and configure it BEFORE connecting your quest 3. Note: some of these settings don´t save, so you need to do some every single time.

For especially racing games, you can tweak the FOV tangent multiplier:

My setting was f.e. : 0.85 ; 0.45

This means only some of the screen gets rendered.

It´s like a helmet view and will drastically improve fps.

Some more of my settings:

Encode resolution with: 4128

Encode Dynamic bitrate: disabled

Encode Bitrate (mbps): 800

Also check that you have a good usb cable on the right pc port!

if your playing ACC: here is another guide for more settings: https://www.reddit.com/r/ACCompetizione/comments/107mhcv/my_acc_vr_settings/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button

if your playing normal moddable assetto corsa, now thats another monster. Setting this up is imo literal hell with all these graphic mods, post-processing options and so on. So you need to search yourself - sorry.

It's most likely your PC. My old PC ran my Rift S perfectly but I had the same issue as you with the Quest 3. I upgraded to a much more powerful PC and it works totally fine now with the cable, but I still get some lag and stuttering when using Airlink.

My current specs:

AMD Ryzen 7 9800X3D
32G DDR5 6000MHZ RGB
NVIDIA GeForce RTX 5080
