## Summary
GE-Proton 11-10 was released with component updates including Wine bleeding-edge 2026-10-16, DXVK v3.1.1-134, and FEX-2610-30. The update adds ACE anti-cheat driver fixes from dwproton for Arknights: Endfield, resolves a PlayStation controller XInput fallback bug that caused severe FPS drops in Path of Exile and other titles, and switches KDE Plasma HDR detection to use KWin's per-monitor HDR state. Star Citizen and Call of Duty: Ghosts also receive targeted fixes.

## What changed in GE-Proton 11-10
- **Wine**: Updated to Valve bleeding-edge 2026-10-16 with Syscall User Dispatch for upstream syscall emulation, native-syscall handling for EAC (EOS) launchers, Xalia clean shutdown, Witcher 3 controller rescan fix, and ddraw paletted surface fix. PROTON_LIMIT_ADDRESS_SPACE removed upstream.
- **DXVK v3.1.1-134**: D3D9 texture, StretchRect and device-reset fixes; D3D8 CopyRects rework; EA anti-cheat code-signing crash workaround; shader cache fixes; zero-initialized shader scratch memory for Call of Duty: Ghosts.
- **VKD3D-Proton**: Synchronization fixes around queued transfer operations.
- **Controllers**: PlayStation XInput fallback no longer rescans all HID devices on empty slot polls, fixing ~50 FPS cap in Path of Exile and slowdowns in Le Mans Ultimate and Story of Seasons. Sackboy and Rune Factory 4 default to PROTON_SONY_AUTO_XINPUT=0. Bluetooth DualShock 4/DualSense rumble works through XInput fallback without breaking input.
- **HDR**: KDE Plasma now uses KWin per-monitor HDR state instead of global brightness checks.
- **Arknights: Endfield**: ACE anti-cheat driver fixes ported from dwproton including kernel-mode DriverEntry return address, MmCopyMemory/ServiceKeyName/MDL section views/PsGetContextThread ntoskrnl fixes, and stub lsass.exe service. Bugcheck 0x65636154 remains unresolved.
- **Performance**: Faster shared SRW lock releases reduce ntdll time; Microsoft Flight Simulator 2024 drops from 24.5% to 19.1% CPU in lock-heavy paths.

## Why it matters
The controller polling fix resolves a regression introduced in GE-Proton 11-8 that affected multiple popular titles, while the ACE anti-cheat driver work represents continued community effort to support kernel-level anti-cheat on Linux. The KDE Plasma HDR improvement benefits Steam Deck users who dock to HDR displays.
