Switchyard Wine Runtime 34a09170d37

Highlights

• Restore Overwatch 2 startup by permitting generated Windows code to become executable in Wine's reserved address spaces on no-preloader macOS builds.
• Keep the reserved Mach-O segments read/write initially while allowing VirtualProtect to add execute permission when Windows applications request it.

Validation

• The executable-memory regression test passed and verified executable maximum protections on both reserved segments.
• Overwatch 2.23.1.1 (build 151722.1; executable 2.23.1.20650) reached the logged-in main menu with GPTK 4.0 beta 1 supplied externally.
• TLS HTTP, native callback exception dispatch, fresh-prefix, Developer ID signature, and Apple notarization checks passed.

Switchyard Wine Runtime 499b1b79c11

Highlights

• Prevent progressive D3D12 frame-rate degradation during long play sessions by replacing fixed descriptor, resource, and timestamp tracking tables with dynamically allocated keyed tracking.
• Release per-object tracking state at final COM release and reuse callback vtable clones without narrowing existing COM identities, preventing unbounded VM mapping growth.

Validation

• Extended GTA V Enhanced Story Mode play remained stable without the previously observed progressive frame-rate collapse.
• D3DMetal D3D12 callback, descriptor-churn, resource-reuse, and Chromium GPU fallback probes passed with GPTK 4.0 beta 1 supplied externally. The post-churn descriptor benchmark completed at 0.85x the warm-up interval.
• TLS HTTP, WoW64 large-address-aware, assertion logging, source integrity, fresh-prefix, Developer ID signature, and Apple notarization checks passed.

Switchyard Wine Runtime 9a822257b1f2

Changes

• Relocates shared native callback thunks to a dedicated high-address, top-down region so late D3D12 command-queue methods can be hooked reliably.
• Keeps general native callbacks on the existing low-address, bottom-up allocation path to preserve GPTK 3 compatibility.
• Fixes the bundled GPTK tests to run with the system Bash 3.2 included with macOS.

Validation

• Visually confirmed the GTA V Enhanced Story Mode selection screen on both GPTK 3 and GPTK 4.
• Confirmed that the Rockstar Games Launcher library screen renders without becoming transparent.
• Confirmed that Steam remains open after its update check and displays the signed-in Store page.
• Confirmed body rendering on example.com in Windows Chrome 150.0.7871.184.
• Passed GPTK 3/4 D3D12 smoke tests and regression tests for native callback exception handling, DXGI cross-process shared resources, TLS, WoW64 LAA, AMD AGS, the Steam overlay, and WGL.

GTA V Enhanced was launched with -nobattleye for Story Mode validation. Online modes that require BattlEye were outside the scope of this validation.

Distribution

This archive does not contain non-redistributable Apple GPTK or D3DMetal files. Switchyard combines it with a GPTK 3 or GPTK 4 installation supplied by the user.

Switchyard Wine Runtime 1917e45cc0a6

Changes

• Keeps shared D3D12 command-queue callback thunks in the low 32-bit compatibility range, preventing GTA V Enhanced from remaining indefinitely in loading state 6 at “Initializing”.
• Preserves Windows exception dispatch while returning from native D3DMetal callbacks, including nested callback unwinds.
• Adds GPTK 4 callback ABI support while retaining the GPTK 3 path, and stabilizes D3D12 callback caching, timestamp readback, Agility SDK proxying, and Chromium graphics fallback.
• Adds AMD AGS/ADL compatibility modules, WDDM 2.7 capability reporting, optional macOS MSync synchronization, additional Steam overlay hotpatch support, and a selectable Mesa llvmpipe OpenGL backend.

Validation

• Entered GTA V Enhanced Story Mode through PlayGTAV.exe -nobattleye on both GPTK 3.0 and GPTK 4.0 beta 1 runtimes.
• Rechecked Steam, Terraria, Poppy Playtime, RV There Yet?, Battle.net, Overwatch, KakaoTalk, Blender, and Rockstar Games Launcher on the GPTK 4 runtime.
• Passed the Wine-only runtime regression suite and launched Epic Games Launcher 20.1.5 with Mesa llvmpipe.
• Signed with Developer ID and accepted by Apple notarization (884c3b89-2978-4c39-979d-759f20538d57).

The downloadable runtime contains no Apple Game Porting Toolkit files. GPTK 3 or GPTK 4 overlays must be supplied separately by the user.

Switchyard Wine Runtime eeb99326c247

Changes

• Prevents Steam and Chromium/CEF windows from turning white during window moves, surface recreation, and popup or hover-menu updates.
• Hosts foreign compositor surfaces and layers in native views, preserves their pixel formats, and restores compositor layers when content views change.
• Improves foreign-surface presentation by waking remote layer hosts, keeping partial presents on the OpenGL path, waiting for command-stream progress, and pacing frames.
• Bridges native D3D12 object callbacks and falls back to a D3D11 device for Direct2D DC render targets.
• Guards stale 32-bit Rosetta returns, preserves activation-context lookup results, and corrects WS_EX_COMPOSITED paint processing.
• Hides windowless helper processes from the Dock.

Switchyard Wine Runtime 34fb5abd4109

Changes

• Fixes writable shared PE image mappings on macOS, resolving the Heartopia themis_x64.dll .mdata failure.
• Implements the Windows.System.DispatcherQueue activation factory required by Heartopia.
• Adds missing server and DLL APIs exercised by Steam.
• Bridges native D3DMetal/DXGI callbacks for Chromium and CEF web textures, and stabilizes adapter callbacks.
• Preserves cycle-time reporting for exited processes and propagates XAudio2 mastering-voice creation failures.

Switchyard Wine Runtime b21d80bd0b83

Initial release

This first Switchyard runtime release contains every downstream change from the pinned WineHQ base through this tag.

Highlights

• Adds Apple x86_64 native callback bridges, TEB/TSD and stack preservation, PE-region registration, WoW64 transition recovery, and macOS exception handling for native graphics interoperability.
• Builds the Chromium/CEF compatibility path across foreign Win32 surfaces, remote Core Animation layers, DirectComposition roots and popups, cross-process hosting, input routing, sandbox profiles, and GPU fallback.
• Improves Vulkan, OpenGL, Direct3D, DirectComposition, layered-window alpha, partial presentation, texture readback, renderer selection, and client-drawn window behavior on macOS.
• Adds targeted Windows API and application compatibility fixes for manifests, RPC, networking, cryptography, media, setup, text scaling, performance counters, and Unity runtimes.
• Integrates macOS behavior for Command-C/Command-V, fullscreen focus, default audio-device changes, Dock and system-tray icons, registered URL protocols, and multilingual font fallback.
• Establishes source verification and a standalone Wine-only runtime workflow with redistributable TLS, Vulkan/MoltenVK, font dependencies, code signing, and notarized archive generation.
