driver_kinectV1 VS ALVR

What software and Kinect are you using? I had the same problem with Kinect2VR on the X360 kinect, I fixed it by using another program. It's way more responsive, precise and let's you add up to 20 trackers for every joint, but calibration and installation are a pain in the ass.

There's no readymade solution for using Kinect skeleton tracking for live avateering. so if you want to stream, you'll need to grab yourself a VR headset as well, then you can use something like https://github.com/SDraw/driver_kinectV1/ plugged into https://akira.works/VirtualMotionCapture-en/ or http://deatrathias.net/TW/

while for normal 6 point tracking you'd normally use https://k2vr.tech/ for best results, For 11 point tracking you'll need to use https://github.com/SDraw/driver_kinectV1 . It doesn't have skeleton flipping and smoothing but it does offer you 11 point tracking.

They also achieve very low latency, I didn't follow every single optimization they added but it basically boils down to a few encoding tricks (better image in the center, accept blurriness in the peripheral vision), good network infrastructure, and hardware decoding / encoding being really fast.

To use steamvr on flatpak I used this tutorial . There was a disclaimer that nvidia GPUs are not supported, but the guy that suggested it has a 3090, so it might work for me too.

They have a Wiki page on GitHub with a settings tutorial and troubleshooting. A downside with a lot of open-source software is that it's relatively difficult to setup but it might fix some of your issues.

You can play wirelessly using Air Link, Virtual Desktop, or ALVR.

They also have a detailed wiki page on GitHub

Quest 2 needs some workarounds (dev mode account), but once you've done those you can just install ALVR (I recommend nightly). As for the games, check ProtonDB. Some VR games (Pavlov beta, for example) have EAC that blocks proton. Some VR games don't work with ALVR due to https://github.com/alvr-org/ALVR/issues/1392, like the Pavlov beta and Crawlspace. Just install the proprietary NVIDIA drivers and use Xorg and most things should work fine. Steam has Proton, which lets you play Windows games with high performance.
