Proton-CachyOS 11.0 arrives with fixes for Wuthering Waves
The CachyOS compatibility layer rebases onto Proton Experimental 11.0 and restores missing cutscenes in several PC games.
CachyOS has pushed out Proton-CachyOS 11.0, a compatibility-layer release that rebuilds the project's Wine patches on a new base and repairs missing video in several games Linux players keep coming back to.
The build, tagged 11.0-20261005, moves the stack onto Proton Experimental 11.0-20261001 and folds the project's Wine work onto a single upstream-derived base instead of carrying a long list of individual patch series. That change is mostly housekeeping for players, but it should make future releases quicker to assemble.
What the update fixes
Video playback has been restored in Witch on the Holy Night and GTA San Andreas, both of which had shipped without playing their cutscenes on earlier builds. Cutscenes that went missing in Wuthering Waves after its 3.7 update are back as well.
The Albion Online launcher should also stop crashing, after the team imported the icuuc.dll and icuin.dll modules from upstream Wine. Elsewhere, the winepipewire.drv driver has been updated to clear up problems reported since it first landed, and Brazilian ABNT keyboard layouts behave properly under winewayland.drv.
The bundled components move forward too: d7vk reaches v2.3, and dxvk-sarek, dxvk-low-latency, vkd3d-low-latency, nvidia-libs and protonfixes are all refreshed. The protonfixes bump carries a patch that hides the Wine version from The Witcher 3.
Per-game settings and packages
Proton-CachyOS will now load a user_settings.py file from the target game's compatdata directory as well as from the Proton installation directory, which lets a per-title tweak live beside the prefix it belongs to. Builds are published for x86_64, x86_64_v3 and arm64; the maintainers still suggest most people stick with the plain x86_64 package.
Our opinion
Niche compatibility patches rarely make headlines, but this is how Linux gaming quietly gets better. Fixing a cutscene here and a launcher crash there is unglamorous work, and it matters far more to the person who can finally finish a game than any benchmark chart. The rebase onto a tidier Wine base is the real story: less patch drift means fixes arrive sooner, and that compounds for everyone using Proton, not just CachyOS users.
