Source? For scientific reasons I swear 😵‍💫

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?

Yes, but it’s packaged separately on Arch

RADV is only important when you want to use Vulkan, OpenGL is a part of Mesa package

vulkan-radeon is radv

I’d say install vulkan-radeon package first and then uninstall Nvidia drivers, otherwise some packages might complain about missing dependencies, ex. Steam

I get the “sign in to confirm you’re not a bot” message on Proton

OnlyOffice exists on Flatpak too

The Finals uses Easy Anti-Cheat so I’d be careful with driver overrides

They only just now updated their FSR to version 3.

It’s on the “extra” repo

Recent Python 3.13 update broke the ProtonVPN client

Foobar unfortunately is closed source, which OP has mentioned as a requirement.

But agreed, it’s so good I use it on Linux through wine, despite many alternatives

Which variant of it, if I may?

Banking has luckily not affected me after degoogling, however Revolut (which I’ve used maybe once a year) is a notable exception where I can’t get it to work

Taxi - Bolt works, just make sure you have microG correctly set up

Phone - avoid Exynos/Mediatek devices as those are less likely to work correctly once degoogled or you change it’s ROM. I used to have an Xperia 5 III with LineageOS on it, everything worked on it including VoLTE and Sony’s stock camera apps.

An effect of the Steam Deck I was not expecting

I’m surprised how much data software running in user-space (at least on Windows) can query

I really hope Proton 10 will have some sort of Wayland support, even if it would be hidden behind an environmental variable
