Wish I knew it

The game uses Anti-Cheat Expert which notoriously blocks any device running Linux, other than the Steam Deck LCD (yes, OLED is blocked too)

I don’t need one, thanks

Only with primary lens

Degoogled version is €50 more, for whatever reason

I want my photos to be grainy, with natural lens distortion, instead of current trend of pictures being shouty to look good on social media

You’re correct

No AOSP, no purchase

OP says the website you’ve linked cannot be reached by them (neither by me).

Would be nice if said app was on the Steam Store or Flatpak, rather than a download you have to do to yourself, but I guess one step at a time

The throttling message is a bit misleading. In fact it tells you why your GPU can’t reach higher boost clocks, and will say either temperature or TDP/power limit

SteamVR on Linux as of now is a joke, features necessary to experience VR without getting nausea are missing, namely working asynchronous reprojection and correct vsync_to_photon timings.

I’m using HTC Vive Pro on Arch Linux (one of 4 SteamVR native headsets) for context.

There is an open-source alternative called Monado which does work better than SteamVR, but it’s game compatibility is a hit or miss, and you don’t get features like Chaperone/Guardian on it

Which proton version do you use?

Lucida.to but it’s for other lossless streaming services (Qobuz, Tidal, Deezer)

They say their device restarts at 4 am but they don’t seem to show how to set it up. On my Note 10 I don’t seem to have this feature with stock LineageOS, maybe they’re running a modified version of it, like Resurrection Remix

Stock LineageOS doesn’t seem to have that feature

A part of the “Verified” or “Playable” badges is the performance of a game on a Steam Deck. If it can’t run well at all, it will get an “Unsupported” badge, ex. the remake of Silent Hill 2.

My knowledge here is limited so I apologise if I’m not being helpful, but at least in case of Arch there’s a special kernel flag (amdgpu.performancemask iirc) to allow OC of your graphics card, are you passing one in your setup?

Have you tried using CoreCtrl instead?
