Proton Experimental Patch Notes: Vermintide 2 Fixes — Feb 2026
- Feature: Improved compatibility for Warhammer: Vermintide 2
- Feature: Expanded controller support for third-party game launchers
- Version: Proton Experimental (Update released February 27, 2026)
- Platform: Linux / SteamOS (Steam Deck)
If you have been rocking a Steam Deck or a dedicated Linux rig, you know that the "Experimental" branch of Proton is where the real magic happens. Valve’s latest drop for Proton Experimental, landing just a few days ago on February 27, continues to hammer away at the two biggest pain points for the platform: specific high-profile game compatibility and the absolute "launcher hell" we all have to deal with. At In Game News, we have seen these updates range from minor bug fixes to literal game-changers, and this latest update for late February 2026 definitely leans toward the latter for co-op fans.
Vermintide 2 Gets the Proton Polish
The headline fix here is for Warhammer: Vermintide 2. While the game has been "playable" in various capacities for a while, it has often been a bit of a mixed bag when it comes to stability and performance on Linux-based systems. This update specifically targets improvements for the title, ensuring that those of us who spend our weekends smashing Skaven can do so without the compatibility layer getting in the way.
In our take, focusing on older but still highly active multiplayer titles like Vermintide 2 is a smart move. It shows that Valve isn't just chasing the newest AAA releases, but is also committed to the long-term health of the Steam Deck’s library. For a game that relies so heavily on timing and fast-paced co-op action, any improvement to the Proton translation layer is a direct buff to the player experience. It’s all about removing that friction that usually comes with running Windows-native binaries on a Linux backend.
Fixing the Launcher Nightmare
The second major part of this update is arguably more important for the general QoL of the handheld scene: better controller support for launchers. We have all been there—you fire up a game on your Deck, only to be met with a tiny, non-responsive window from EA, Ubisoft, or some other third-party publisher. Usually, this requires using the trackpads or the touch screen to navigate a menu that was never meant for a controller. It’s a total vibe killer and often feels like the weakest link in the SteamOS chain.
By baking more controller support for these launchers directly into Proton Experimental, Valve is trying to make that transition from the Steam UI to the actual gameplay as seamless as possible. While we still wish these launchers would just go away entirely, making them navigable with a thumbstick is a massive win for anyone who hates having to "mouse" around with a joystick. It’s these kinds of under-the-hood tweaks that help the Steam Deck maintain its lead over other handhelds that struggle with the "handheld-first" software feel.
The Hardware Reality: OrangePi Neo "On Ice"
While the software side of Linux gaming is looking up, the hardware side just took a hit. We were keeping a close eye on the OrangePi Neo, a handheld meant to run Manjaro Linux, but the latest reports are grim. The project is officially "on ice" due to rising component prices. This is a tough break for the community. We always want more competition, and seeing a Linux-based handheld stall out before it can really compete with the big dogs like the Steam Deck or the ROG Ally misses the mark for what we hoped 2026 would look like for hardware diversity.
It really puts into perspective how much of a lead Valve has. They can eat some of the hardware costs because they own the storefront, whereas smaller players like the OrangePi team are at the mercy of the fluctuating parts market. For now, it seems the "Manjaro handheld" dream is on the backburner.
Indie Wins and Future Horror
On a lighter note, the source highlights some interesting shifts in the indie space that Linux gamers should keep on their radar. We’ve seen Gambonanza, which is being described as a "Balatro-like" version of chess. Given how Balatro absolutely wrecked the productivity of our entire office last year, seeing that roguelike formula applied to chess is something we are both excited and terrified of. The demo is already winning people over, and it’s exactly the kind of game that feels right at home on a Proton-powered device.
Finally, there is a new announcement from Running With Scissors, the team that gave us the POSTAL series. They are shifting gears into horror with a new first-person shooter titled Flesh & Wire. It’s a bit of a departure from their usual brand of chaotic comedy, diving back into the darker roots of the studio. For those of us who grew up with the grittier side of 90s and early 2000s shooters, this is one to watch. Between these new titles and the constant QoL updates to Proton, the Linux gaming ecosystem is staying aggressive, even if the hardware side is facing some pricing headwinds.
