Valve’s Steam Deck handheld may very well be the beginning of one thing stunning for Linux avid gamers; proof that the working system is greater than able to working your favorite video games on the go. But even earlier than its launch the PC gaming handheld may be paying dividends for Linux gaming, as Valve and AMD be a part of forces to enhance CPU efficiency on the open-source OS.

Valve’s upcoming handheld gaming PC, the Steam Deck, is constructed round an AMD APU, which incorporates each a Zen 2 CPU and RDNA 2 GPU. It is a Linux-based system, powered by SteamOS 3.0, an working system switching to make use of the Arch Linux distribution. Meaning it can solely have the ability to run Home windows video games by way of a compatibility layer, so for that Valve has Steam Play, often known as Proton.

The Steam Play compatibility layer is how the Steam Deck will run video games constructed for Home windows, which most are, and is essential for Valve to get working as easily and effectively as attainable.

As Phoronix notes, AMD and Valve are actually working collectively on bettering the efficiency and energy effectivity of the ACPI CPUFreq driver, which straight pertains to CPU frequency and energy scaling, when used along with Steam Play.

“[The ACPI CPUFreq driver] was not very efficiency/energy effectivity for contemporary AMD platforms,” Phoronix quotes, “a brand new CPU efficiency scaling design for AMD platform which has higher efficiency per watt scaling on reminiscent of 3D recreation like Horizon Zero Daybreak with VKD3D-Proton on Steam.”

Offering the prevailing ACPI CPUFreq driver is leaving efficiency on the desk, which it reportedly is, a a lot improved driver ought to have the ability to give Linux extra direct and efficient management over the CPU for higher processor efficiency with Steam Play. 

Primarily, it is going to be giving Linux machines the means to raised use the {hardware} at their disposal. That is necessary while you’re making an attempt to eke out each little bit of efficiency from a battery-powered PC gaming machine such because the Steam Deck. 

Valve hopes to nail down 30 fps gaming with the Steam Deck, and with the restricted GPU energy obtainable onboard, it can want to ensure the working system and drivers are as streamlined as attainable to ship.

I think Valve and AMD will each intention to push additional optimisations to the Linux driver bundle within the coming months. Valve to provide the Steam Deck the most effective likelihood when it arrives this December, and AMD to raised help its {hardware} ecosystem with optimum drivers for its companions. And to raised rival Intel, after all.
