Xbox PC games, distributed through the Xbox app, fail to run on Linux because of Microsoft's proprietary GDK runtime environment. This also breaks Game Pass even though the company supports cloud streaming Game Pass titles. A new open-source project from the developers of Heroic Launcher, called "Xodus," is aiming to fix this by reverse engineering and emulating the necessary components required for Xbox PC games on Linux.

Xodus primarily targets modern, GDK-based Xbox PC titles and their MSIXVC packages; not older, UWP-based releases like Gears of War 4 and early Forza Horizon games. The problem with those isn't the DirectX API or x86 instructions; Proton and DXVK/VKD3D can already translate those. That's also the reason why you can still run Xbox PC games on Linux if you somehow get your hands on the DRM-free executables.

The real issue is the trifecta of Microsoft's proprietary GDK (Game Development Kit), Xbox identify services, and encrypted MSIXVC packages. This framework is responsible for verifying licenses for the games you own through the Xbox app. Without it running in the background, the games will simply crash right as you try to open them, or not launch at all. This is where Xodus comes into play.

The Xodus team says the project can already log into Xbox services, download game packages and obtain game licenses. It includes its own open-source implementation of the xgameruntime.dll and custom forks of both Wine and Proton, along with xal-rs, which is an Xbox authentication library for Rust. Xodus uses proxy libraries to interface with GDK games and intercepts API calls to transmit valid Xbox Live tokens.

For now, efforts are focused on emulating the Xbox Gaming Runtime from the Xbox GDK through Wine, then the project will move on to actually launching and playing Xbox PC titles locally. Considering they've already solved the Xbox/Microsoft authentication, license check, and package decryption hurdles, it shouldn't be long before we see PC Game Pass running natively on Linux.

BedrockonLinux 2.0, another open-source project that brings Minecraft Bedrock to the platform, already relies on similar reverse-engineering tech to handle these components since Microsoft migrated the game to GDK. This allows the game to talk to Xbox Live in real-time through a secure doorway to authenticate tokens despite the game running in a sandboxed environment like SteamOS (Linux).

Microsoft itself brought four original Xbox titles to PC last month and it says more are coming, along with leaked documents suggesting Xbox 360 titles also releasing on PC next year. These games come with a baked-in Xbox 360 emulator. It's not clear if these games use the same GDK stack as native Xbox PC titles, however.

Windows is in a tough spot right now, with years of neglect and stagnation reaching a boiling point with customers. Lack of optimization, bloat, ads, forced AI slop, and persistent tracking have forced Microsoft to admit its missteps and commit to fixing the OS at large. Windows Latest's new testing shows that the built-in weather app is a perfect representation of the state of Windows. The "app" consumes up to 1.2GB of RAM while idling, and it serves up a bunch of ads while you check the temperature.

MSN Weather is the default weather app that ships with Windows, which explains why it's filled with promotions throughout, despite being part of a paid OS. To be clear, the app looks very modern and has all the data you could ask for, such as live radar overlays, hourly wind and precipitation breakdowns, air quality index, and moon phases. It's also accurate because the data is sourced from a bunch of different providers across the world, but mostly Foreca.

The author explains that getting accurate forecasts is not a cheap endeavor, so it's not like Microsoft is running a charity. But the comparison falls apart when you look at what the competition is offering. Apple's native weather app on macOS is just as beautiful, detailed, and accurate, yet it's free of ads. It also only consumes about 250MB of memory to show all that data, so 5x less than Windows. This is because MSN Weather is technically not even an app to begin with; it's a web wrapper that's pinging a bunch of browser tabs in real-time.

When the author clicked on the Task Manager entry for MSN Weather, they saw 8 Chromium-based subprocesses, confirming that they're just looking at a website being rendered via WebView 2. For context, native Windows apps are supposed to adhere to the WinUI framework, which the company is slowly adopting over Win32 and UWP. Microsoft is committed to updating all the native apps Windows ships with to Win32, which should significantly improve their optimization, but we don't know if the ads will suddenly disappear as well.

The author saw Adobe Acrobat ads while checking the forecast, and we saw two ads — one for LendingTree and another for Spotify. Apart from that, scrolling around the app and clicking on the different menus and boxes was fast enough. We have to emphasize that the app really is granular and well-built from an aesthetic point of view; Microsoft gets full points for that, or is it MSN? That distinction is another issue that makes the weather app conundrum a bit more confusing.

When Microsoft promised to rebuild all native Windows 11 apps, it didn't explicitly say those would include MSN-branded services too, like MSN Weather and MSN News. Seeing as though they're simply called by their utilitarian names in the OS, there's a strong chance that these memory hoggers will also be eventually upgraded. For now, just stick to your phone, especially if you were among those who immediately Googled how to remove the weather widget from your taskbar that fateful day.
