Universal RTXMFG v1.4.2

V1.4.2 adds more resilient detection for path-traced hair in The Witcher 3, which should help keep the mod working after game patches. On the latest Witcher 3 update, where v1.4.1-hotfix.1 greyed out the Path Traced Hair option, path-traced hair is available again.

For The Witcher 3 DirectX 12, install RTXMFG as winmm.dll beside witcher3.exe. Enable HairWorks, path tracing and Path Traced Hair in the game. Fully restart the game after changing Path Traced Hair or Frame Generation. Hair support remains experimental and may stop working after a game patch; the menu's Path traced hair line shows when it is unavailable.

The ZIP contains only RTXMFG.dll, combining the backend and menu. For an existing single-DLL installation, close the game and replace the installed mod DLL, preserving its chosen filename and your settings. Press Backspace to open the menu. See the README for installation and supported filenames. SHA-256 checksums for the ZIP and extracted DLL are attached.

RTX 30 support remains very early and experimental. The newer RTX 30 development changes are excluded from this release. Vulkan support remains experimental; Dynamic MFG is unavailable on Vulkan.

The release DLL passed all 54 local release regression cases (2,131 assertions), plus hair CPU checks and eight synthetic GPU configurations against two Witcher builds. Path-traced hair was confirmed in game on the latest update with a test build carrying the same hair code; this exact release DLL has not yet been run in game.
