Hey everyone, made a new Decky Loader plugin! Some of you might know me from decky-proton-launch (https://github.com/moi952/decky-proton-launch) — this one's for anyone running SteamOS with an NVIDIA card via steamos-nvidia-installer (https://github.com/moi952/steamos-nvidia-installer).

It lets you pick and install any NVIDIA driver version straight from the running system, right from Quick Access. No USB stick, no repair image, no reinstall.

Only reboot when you're actually ready to.

- Any version from the Arch archive, tagged with NVIDIA's own channel

(Recommended / New Feature Branch / Beta), fetched live.

- Filter which channels show up, and pick which one counts as "latest".

- Real release notes for any version before you install it.

- Live progress log while it runs, Reboot now button when it's done.

- Games, saves, Steam login, Decky untouched — the risky part runs in a throwaway overlay, the real filesystem only gets touched for the final copy.

Already have SteamOS + NVIDIA installed?

You'll need to run a repair once first (the "Upgrade SteamOS (NVIDIA) — keeps games & data" option on the USB) — it'll offer to grow your system partitions to 8GiB, since Valve's stock 5GiB doesn't leave room for a driver install. Fresh installs already get 8GiB by default.

Let me know what you think!

Maybe I’m overthinking this, but does anyone else feel like something weird is happening between Valve and NVIDIA lately?

I started digging through the NVIDIA Vulkan beta driver changelogs:
https://developer.nvidia.com/vulkan-driver

And since late 2025 / early 2026 the acceleration has been kinda insane.

They’re suddenly pushing a huge amount of advanced Vulkan features related to:

• DX12 translation
• descriptor heaps
• ray tracing
• device address commands
• shader memory models
• opacity micromaps
• low overhead GPU scheduling

Stuff that feels VERY relevant for Proton / VKD3D / modern game engines.

What really caught my attention is this:
VK_KHR_device_address_commands was added in NVIDIA’s Vulkan beta drivers on March 13th 2026.

And literally right after that, VKD3D-Proton already started implementing support:
https://github.com/HansKristian-Work/vkd3d-proton/pull/3005

There’s also this newer PR:
https://github.com/HansKristian-Work/vkd3d-proton/pull/3008

And overall there’s been a LOT of recent low-level NVIDIA-focused work in VKD3D-Proton around:

• RT
• descriptor heaps
• opacity micromaps
• advanced Vulkan extensions

Which feels surprising considering SteamOS is still officially AMD-focused.

So now I’m seriously wondering:
are Valve and NVIDIA quietly preparing something together?

Like:

• a SteamOS handheld with NVIDIA silicon?
• a living room console?
• ARM + DLSS + Proton?
• broader official SteamOS support for OEM RTX devices?

Because honestly, the pace NVIDIA is moving at on Linux/Vulkan right now feels completely different from the old “minimum viable Linux support” era.

Maybe I’m completely reaching here, but the timing between NVIDIA driver releases and VKD3D implementation work feels almost coordinated lately.
