Valve is testing ARM64 support for popular games

Valve is reportedly testing ARM64 support for several popular games, which has led to speculation about potential new hardware. A recent leak from SteamDB indicates that games like Left 4 Dead 2, Garry's Mod, and Kerbal Space Program are being evaluated with "proton-arm64" tags, suggesting that Valve is developing a version of Proton tailored for ARM64 systems. This move could enable Valve to run PC games on portable ARM64 devices, possibly as part of a strategy for new hardware, including a standalone VR headset or an updated Steam Deck. The inclusion of Android compatibility, hinted at through mentions of Waydroid, suggests that Valve aims to broaden the software ecosystem available on its platform. The update also lists other games, indicating Valve's intention to create a more flexible, cross-platform gaming experience. While these developments are speculative, they point towards Valve's commitment to enhancing its gaming ecosystem and potentially expanding into new hardware markets.

It seems pretty clear to me that this is for Valve's long-awaited standalone VR headset, Deckard. What other reason would they have to support Gorilla Tag on ARM? https://x.com/SadlyItsBradley/status/1837210246076588500

Compatibility with your existing Steam library out of the box will be a huge competitive advantage for Deckard over Meta Quest.

With SteamOS, they solved their dependency on Windows.

Now, they're trying to stop being tied to x86.

ARM64 is being tested because hardware is already widely deployed, but not being tied to x86 is the important part. Enabling e.g. RISC-V as well.

It would be great if this meant proton is coming back to macOS :)

I don't have high hopes however.

I think, especially considering the news of Qualcomm talking with Intel about acquisition, or just Intel's general problems; we are in the last decade of x86.

Since we're all just reading tea leaves, my guess is Valve is looking at a higher performance, lighter, ARM-based SteamDeck 2. They have time to develop it, so maybe they're targeting the next generation of Snapdragon X.

Would it possible to AOT-recompile from x86 to aarch64? Or will it all be emulated forever?

This is really nothing new. Valve has been supporting fex by paying Alyssa from asahi Linux to work on it for a while.

Great. A native Steam client with and Box64 or FEX integrated into Proton for CPU layer translation, would open up a world of low cost Steam hardware.

Not just VR, commodity gaming devices like a $100 Steam Deck, $50 HDMI dongle consoles and with both a brand new market segment to tap into.

Huh. I wonder if this uses https://box86.org/ or such, like proton uses wine

Interesting - Source 2 has mobile support (not sure if it's native but I assume it is, so maybe it already has ARM support) and Source technically has mobile support but that was done by nvidia Lightspeed Studios I think. Maybe Valve has been quietly adding ARM support to their engines behind the scenes.

> There are also some other tags such as "proton_experimental" and "proton-arm64ec-vanguard"

Could this potentially, have any chance, of being a method/branch of proton able to run the Vanguard anti-cheat, i.e being capable of running Valorant?

It's just a wish, but would be really nice if true.

It's exciting that they are using Waydroid. It would be great for Linux Mobile to have a corporation fund the development so that Android apps can be used where native applications are unavailable.

They are recompiling games they do not own?

That said, this would also be good news for RISC-V if they start providing builds for different ISA than x86(32bits) and x86_64.

Does this mean mac support could be possible
