GloriousEggroll Drops GE-Proton11-5 Hotfix to Fix Easy Anti-Cheat Breakage
GloriousEggroll published another GE-Proton update today and the release notes are mercifully short: HOTFIX: Fix broken Easy-Anticheat loading. It arrived roughly three hours after GE-Proton11-4, which is the kind of turnaround that tells you exactly how badly the previous build was breaking multiplayer games for Linux players.
If you've been following the GE-Proton11 series, you know this branch rebases onto Valve's upstream Proton 11 work. The shift brought in updated Wine patches, fresh DXVK and VKD3D versions, and that new DS5/DS4 haptic support. But it also tripped over Easy Anti-Cheat (EAC). The hotfix steps in to patch that regression, and it's already pulled roughly 3,928 downloads for x86_64 and 265 for aarch64.
Why This Matters for Your Library
Easy Anti-Cheat is the middleware behind Hunt: Showdown, Monster Hunter Wilds, Star Citizen, Black Desert Online, and a handful of other heavily played titles. It sits deep in the kernel and plays poorly with Wine's translation layers, which has made it one of the most persistent friction points for Linux gaming. A breakage here doesn't just nudge a game. It locks you out of your entire library of multiplayer titles until a patch lands.
GloriousEggroll's response time speaks to how much this matters. The commit behind the release (a2b6dae) only bumps the version string in VERSION and proton. The actual code fix was already sitting in the upstream rebase, so GE-Proton11-5 is really just a tagged marker that points users to the corrected build. If you installed 11-4 and watched your EAC games fail to launch, switching to 11-5 should resolve it without you needing to touch your system prefix.
The release also sits alongside two untagged commits on master. One fakes a DS5-to-DS4 mapping for Detroit: Become Human, and the other just adds environment variable notes to the readme. Neither changes how Proton works under the hood, but they're useful if you're chasing specific controller quirks or setting up headless environments.
Getting the Update
You can grab the archives directly from the GitHub releases page. The x86_64 tarball is about 508 MB, and the aarch64 build comes in at roughly 586 MB. SHA-256 digests are published alongside the files if you want to verify integrity before dropping them into your runtime directory.
Head here to the release page for direct download links and checksums.
Keep in mind that if you use protonup, a single protonup --update command will pull this version automatically. Manual users should drop the extracted folder into ~/.local/share/Steam/ubuntu12_32/overlayinfo/ on Steam Deck or the equivalent runtime path on your distro. Once it's in place, launch a title that uses EAC and you should see the anti-cheat initialize without the usual kernel driver complaints.
The GE-Proton11 series has been moving fast. Six weeks ago, GloriousEggroll released the initial Proton 11 rebase, followed by video playback work and a Steam Desktop Global Virtual Device fix. The August 11 batch packs the most hardware-level changes yet, and this hotfix is the safety net for the anti-cheat crowd. It's not flashy, but it's exactly what multiplayer players needed today.
