A triple helping of community Proton builds to report on for you today with Proton-CachyOS 11.0-20261014, DWProton 11.0-15 and GE-Proton 11-10 released. All the changes for each are below, instead of spamming you with multiple articles for different Proton releases around the same time.
If you're confused on all the different versions of Proton - check out the GamingOnLinux Guide!
Proton CachyOS Key Changes- Proton (SLR and Native)
- Updated to Proton Experimental 11.0-20261014 with wine rebased on top of Bleeding Edge experimental-wine-bleeding-edge-11.0-453249-20261016-pf413b3-wc53678a-d6689ca-v0bb64c.
- Updated winewayland.drv to fix pointer constraints and a couple of other issues. Thanks to @BananaWorks07. Issues: CachyOS/wine-cachyos#35.
- Updated winepipewire.drv to fix various issues. The driver will now fall back to async mode instead of crashing if rtkit is missing from the system, although we recommend to install it. Thanks to @M0n7y5. PR: CachyOS/wine-cachyos#36.
- Fixed Arknights: Endfield not working after its latest update. Thanks to @NelloKudo. Issue: https://dawn.wine/dawn-winery/dwproton/issues/74.
- Fixed some games like Loop Hero crashing when using WOW64. Thanks to @NelloKudo. Issue: #308.
- Backported the required changes from upstream Wine to fix Warcraft III v3. Thanks to @NelloKudo. Issue: #292.
- Thanks to the rebase on Bleeding Edge wine both issues with Warhammer 40k: Spare Marine 2 have been resolved. Issues: #305, #302.
- Updated dxvk-sarek to version v1.14.1. Thanks to @pythonlover02.
- Updated protonfixes to 1.0.15-1867-ge89ce7b and removed various stale and broken older fixes from it. Thanks to @BananaWorks07 for the janitorial work.
- Updated OptiScaler integration to also download Streamline SDK files when PROTON_OPTISCALER_STREAMLINE=1 is set. This is not relevant right now but it will be in a future OptiScaler version. As far as I understand, this is not going to be compatible with every game, and thus it's left as a manual option.
- Logs generated by Proton-CachyOS now have the version of the tool used appented to the their filename.
Proton (Native only)
- Added partial support for 32bit PhysX on AMD through ZLUDA, which can be enabled through PROTON_ZLUDA=1. The complete integration is still work-in-progress and as such this feature is available in the proton-cachyos-native package from CachyOS repositories only. The reason is that it requires some very storage-heavy dependencies to build, such as rocm-llvm and hip-runtime-amd and we don't want to force them on the AUR package. Adding support for it in the Steam Linux Runtime package is also unfinished due to these dependencies. The required hip-runtime-amd dependency for this feature to work is optional and will have to be installed manually. It is important to note that for ZLUDA to work properly, you also have to install the latest version of PhysX through winetricks and potentially remove any older PhysX dlls shipped with the applications. This integration has been tested with FluidMark and Mirror's Edge only so far. Please report any issues with this feature in #238.
- To complicate matters, with the recent updates to Steam and the Steam client using SteamRT3, the native build of Proton-CachyOS doesn't work with Steam presently. If it is going to work again in the future is uncertain at this point. It is a known limitation but it still works with umu-launcher.
- Updated Proton and components to cachyos-11.0-20261014-slr.
- Removed outdated Protonfix for NIKKE launcher (#65).
Component Updates
- Wine: Valve bleeding-edge 2026-10-16. This brings upstream syscall emulation through Syscall User Dispatch and native-syscall handling for EAC (EOS) launchers. Also included: Xalia now shuts down cleanly, fewer spurious X11 mouse movement events, a Witcher 3 controller rescan fix, and a ddraw fix for paletted primary surfaces.
- Wine: PROTON_LIMIT_ADDRESS_SPACE and its address-space limits for Reverse: 1999 and Blue Protocol: Star Resonance were removed upstream.
- DXVK: v3.1.1-134. Includes D3D9 texture, StretchRect and device-reset fixes, D3D8 CopyRects rework, a workaround for an EA anti-cheat code-signing crash, shader cache fixes, and zero-initialized shader scratch memory for Call of Duty: Ghosts.
- D7VK: rebased onto DXVK v3.1.1.
- VKD3D-Proton: fixes synchronization around queued transfer operations.
- FEX: FEX-2610-30.
Controllers
- The automatic PlayStation controller XInput fallback no longer rescans every HID device each time a game polls an empty controller slot. Since GE-Proton11-8 this caused large slowdowns, even with no controller connected:
- Path of Exile ran at ~50 FPS instead of 200+ (#862).
- Le Mans Ultimate slow-motion physics with a Moza wheel (#777).
- Story of Seasons: Friends of Mineral Town lost FPS with PROTON_PREFER_SDL (#850).
- Setting PROTON_SONY_AUTO_XINPUT=0 confirmed this was the cause in #862; the fix itself has not been confirmed in-game yet.
- Sackboy: A Big Adventure and Rune Factory 4 Special now default to PROTON_SONY_AUTO_XINPUT=0. This fixes the DualSense being assigned to player two in Sackboy and scrambled DS4 input in Rune Factory (#843). The variable was confirmed by two users.
- Bluetooth DualShock 4 and DualSense rumble now works through the XInput fallback, and input no longer stops after the first rumble (#853, thanks @ilyasbounoua). Native hidraw games on Bluetooth keep the extended controller reports (gyro and touchpad).
- PROTON_SONY_HIDRAW_XINPUT, PROTON_SONY_AUTO_XINPUT, PROTON_DUALSENSE_HAPTICS_PREFER_NON_EVENT and PROTON_DEATH_STRANDING_CONTROLLER_EFFECTS now reach the HID bus driver; previously the driver ignored them.
Wayland and Windowing
- GNOME: fixed games and launchers closing when a window that owns a popup is destroyed (mutter: "destroyed popup not top most popup"). This affected AION 2 and Battle.net auto-login with PROTON_ENABLE_WAYLAND=1 (#834). Not yet confirmed on GNOME.
Video Playback
- MonoGame games no longer stall or crash when a song is played again, for example Picross for a Cause (#839, thanks @Petru101).
Rendering and HDR
- KDE Plasma: HDR detection now uses KWin's per-monitor HDR state. HDR monitors are detected even when SDR brightness is set to the HDR reference level. Other compositors keep the existing detection (#838).
Other Changes
- Arknights: Endfield: added the ACE anti-cheat driver fixes from dwproton (#847):
- DriverEntry is called with a kernel-mode return address.
- ntoskrnl fixes: MmCopyMemory, ServiceKeyName, MDL section views and PsGetContextThread.
- A stub lsass.exe (SamSs) service is added and started.
- This matches dwproton. The remaining ACE bugcheck 0x65636154 is still unresolved there too.
- Star Citizen: loads the game's bundled AMD AGS library again, as GE-Proton11-6 did. This should avoid the EAC "Untrusted system file" violation and error 30033 (#858). Not yet confirmed in-game.
- Faster shared SRW lock releases. Lock-heavy games spend less time in ntdll; Microsoft Flight Simulator 2024 went from 24.5% to 19.1% (#844, thanks @smatkovi).
- Build: clang/libc++ and llvm-libc build fixes (#835, thanks @FireBurn).
