After another while testing Beta versions, the latest SteamVR upgrade is out now although it's quite a small one with mostly minor improvements overall.
Most of the changes don't apply to Linux, as it's tweaking devices that don't support Linux like Oculus and Windows Mixed Reality. However, there's still some goodies for Linux included.
The big one is the inclusion of async-reprojection now for NVIDIA users, which is providing you have installed at least the NVIDIA 470.42.01 driver which is the first to have it. Hopefully this will end up giving NVIDIA VR users on Linux a better experience.
Valve also put out a warning to Index users on safety:
Index Users: Please unplug controllers during gameplay, as pulling the charge cable at an angle may cause damage. If you suspect damage to your controller's USB-C connector, please contact Steam Support. Developers and users who prefer wired controller workflows should consider using a "USB-C breakaway cable".
Slightly annoying though, is that since this update I've now come across an issue where the SteamVR overlay will jitter around, which is really distracting. The bug was sent to Valve back in 2020, so hopefully they figure out what's causing it as it's not pleasant at all.
I'll also take this moment to point out the incredibly useful script our contributor Scaine posted to our forum. I've ended up using it now, to quickly use a keyboard hotkey to turn my Index Base Stations on and off. It works really nicely. Still weird this feature isn't hooked up for Linux in the Steam client.
