I can speak from experience having used both wired (Index) and wireless (Pico 4 with ALVR) VR on Linux and the performance and stability is horrible. Always has been sadly. I can play some VR games on Linux but overall it’s not worth it in the current state.
If you rely on it that much maybe its time to download it all and keep it.
Just like Windows 10 was announced to be the last Windows version and it was supposed to be a rolling release product.
And then they needed to artificially restrict what hardware Windows runs on to please the OEMs and their computer sales so we got Windows 11, cutting off a lot of recent and still more than capable enough hardware ¯\_(ツ)_/¯
Nvidia does more than just GPUs.
Nvidia makes both SoCs like the Tegra series and server CPUs (Grace; ARM based to be used with their ML/AI cards with much higher bandwidths than regular CPUs).
Nvidia also just announced that they are working on a consumer desktop CPU.
