While Apple laptops have never really been the first stop for PC gaming, Linux is slowly shaping up to be an excellent gaming platform, largely thanks to open-source development efforts as well as work from the likes of AMD and NVIDIA, who have both put significant work into their respective Linux drivers in recent years. This makes efforts like the Asahi Linux Project all the more intriguing. Asahi Linux is a project that aims to bring Linux to Apple Silicon Macs—a task that has proven rather difficult, thanks to the intricacies of developing a bespoke GPU driver for Apple's custom ARM GPUs. In a recent blog post, the graphics developer behind the Asahi Linux Project showed off a number of AAA games, albeit older titles, running on an Apple M1 processor on the latest Asahi Linux build.

To run the games on Apple Silicon, Asahi Linux uses a "game playing toolkit," which relies on a number of custom graphics drivers and emulators, including tools from Valve's Proton translation layer, which ironically was also the foundation for Apple's Game Porting Toolkit. Asahi uses FEX to emulate x86 on ARM, Wine as a translation layer for Windows apps, and DXVK and vkd3d-proton for DirectX-Vulkan translation. In the blog post, the Asahi developer claims that the alpha is capable of running games like Control, The Witcher 3, and Cyberpunk 2077 at playable frame rates. Unfortunately, 60 FPS is not yet attainable in the majority of new high-fidelity games, there are a number of indie titles that run quite well on Asahi Linux, including Hollow Knight, Ghostrunner, and Portal 2.

In a notable step forward for the RISC-V architecture, the Box86 and Box64 emulator developers have successfully run The Witcher 3 on a RISC-V processor. While performance is far from optimal, even on a Milk-V Pioneer with a 64-core processor and an AMD Radeon RX 5500 XT graphics card, the achievement is remarkable.

RISC-V, a free and open-source instruction set architecture, is still in its early stages compared to established platforms like ARM and x86/x64. Despite this, the Box86/Box64 team, known for creating environments to run Windows programs on Linux, has demonstrated that AAA gaming is possible on RISC-V hardware. To accomplish this feat, the developers utilized Box64 with Wine and DXVK to emulate the necessary instructions.

A couple of days ago, Valve has released the first stable version of Proton 9.0, a compatibility layer for Windows games to run on Linux-based operating systems. The newest stable version is built on Wine 9.0 and brings all the improvements and fixes seen in earlier beta releases.

According to the release notes, the new Proton 9.0-1 enables some games that were previously playable only with Proton Experimental, including Sonic Colors: Ultimate, Command & Conquer games, The Finals, Lord of the Rings: Gollum and others, enables NVIDIA NVAPI by default for most games, adds support for Steamworks SDK 1.59, and fixes a bunch of other issues in a lot of games. The new version also limits the number of cores seen by some games in order to make them actually playable on CPUs with high core count, including Far Cry 2 and Far Cry 4, The Witcher 2: Assassins of Kings Enhanced Edition, a couple of Warhammer 40,000 games and others.

Apple has struggled in the area of offering comprehensive gaming ecosystems - in the personal computer space - over the past few decades with only a handful of studios bothering to port their games over to macOS, but material presented at this week's Worldwide Developers Conference (WWDC) indicates that the technology giant is getting serious about its silicon becoming a legitimate platform for video games. A lot of the company's presentation focused on the controversial Vision Pro Headset, but some press outlets took notice of a quieter announcement during proceedings. Hideo Kojima (of Metal Gear Solid fame) made an appearance and announced: "I have been a die-hard Apple fan since I bought my first Mac back in 1994—and it has been a dream of mine to see my team's best work come to life on the Mac. Death Stranding Director's Cut on the Mac takes advantage of the latest Apple technologies to provide the best experience to our fans." Several other development outfits have also declared that their games are set for arrival on Mac systems this year. Apple was enthused about this new strategy and let everyone know that: "tens of millions of Macs can run demanding games with outstanding performance, exceptional battery life, and breathtaking visuals."

Susan Prescott, Apple's vice president of Worldwide Developer Relations stated: "A new era for gaming on Mac is here...Developers around the world can harness our powerful tools in Metal 3 to deliver incredibly responsive gameplay with high frame rates to more players than ever before." Their software engineering team has been working on a system that simplifies and accelerates the process of creating Windows-to-Mac game ports. A Proton-esque environment - comparable to Valve's software layer efforts with Steam Deck - is capable of translating and running the latest DirectX 12 Windows titles on macOS. Codeweavers revealed in a blog post that Apple has chosen to base the Game Porting Toolkit on their CrossOver source code.

When Valve claimed that their Linux-powered Steam Deck device would be able to run any game from the Steam library most of us assumed this was simply a statement on the power of the device. We assumed that the Linux OS wouldn't be compatible with certain games such as those using Easy Anti-Cheat (EAC) or BattlEye however Valve confirmed that they would work with the companies to add support. This has culminated in Epic Games recently introducing Linux & Mac support for their EAC software noting the Steam Deck in their announcement.

The addition of Linux support has been specifically designed to work with the Wine and Proton compatibility layers to ensure that all games using the software should run correctly. This will mean that titles such as Apex Legends, Dead by Daylight, War Thunder, 7 Days to Die, Fall Guys, Black Desert, Hunt: Showdown, Paladins, and Halo: The Master Chief Collection can now be easily updated to include Linux support. The rival BattlEye software isn't currently available for Linux but the CEO has confirmed that support will be added with the first game featuring it coming soon. These moves will drastically improve the Linux gaming landscape and will hopefully encourage more developers to natively support the platform.

Proton is a new tool released by Valve Software that has been integrated with Steam Play to make playing Windows games on Linux as simple as hitting the Play button within Steam. Underneath the hood, Proton comprises other popular tools like Wine and DXVK among others that a gamer would otherwise have to install and maintain themselves. This greatly eases the burden for users to switch to Linux without having to learn the underlying systems or losing access to a large part of their library of games. Proton is still in its infancy so support is inconsistent, but regularly improving and the list of supported Windows games is growing each day.

In fact, this project has announced that it has now over 2,500 Windows games (2,663 at the time of writing) that work on Linux with Proton and Steam Play. Beyond those supported "whitelisted" games, there are several others that although not-whitelisted are supported and "play just as well as on Windows". Some examples are "No Man's Sky", "The Witcher 3: Wild Hunt", "Wolfenstein: The New Order" or "The Elder Scrolls V: Skyrim". Any user can contribute and report about the titles in his game library thanks to ProtonDB.

There is light in the end of the tunnel for proponents of a native-Linux version of Valve's Steam platform, as a Steam for Linux is just months away, according to a Phoronix report. Linux has been hiring developers with experience in Linux OpenGL applications for some time now, and the gearwheels at Valve have been able to drive out an early version of Left 4 Dead 2 that was seen running native on Linux (Ubuntu 11.10), without translation layers such as Wine, utilizing the OpenGL API, with the ICD provided by AMD Catalyst. Although first denied in 2010, Valve is back to the idea of Steam for Linux, thanks to its "flat" company structure that lacks a hierarchy. Following the footsteps of Steam for Mac, Valve could port some of its games to Linux, and give the client SteamPlay capability.

Linux and Unix owners already know and love Wine. No, silly, not the red/white alcoholic beverage, the program. Wine, which has been in development for some time, is a program that allows Linux and Unix users to run Windows applications in a Linux/Unix environment. Wine is getting ever closer to a final version, and this Release Candidate 2 shows this in the list of changes. All that the authors changed from RC1 to RC2 is a list of bugfixes, which can be found here. If you'd like to download the latest version of this revolutionary program, you can check it out here.
