Changes

OptiPatcher upgraded to rolling release (base v0.39, 2026-04-17)

Switches from the pinned v0.30 build to the latest rolling release snapshot. Notable additions over v0.30:

• Clair Obscur: Expedition 33, Oblivion Remastered, Mafia The Old Country
• South of Midnight, ROMEO, Windrose, Super Meat Boy 3D
• Soulstice, Star Trek Voyager, Samson, VOID/BREAKER fixes
• I Am Jesus Christ, Half Sword, Bellwright, Deadzone Rogue
• ~80 additional game entries vs v0.30 — more games will have DLSS/DLSS-G options unlocked

The rolling build is pinned at a verified sha256 on a stable URL so plugin installs are reproducible.

v0.15.2

Changes

fix: drop nvngx.dll

The nvngx.dll bundled from the OptiScaler v0.7.8-pre0 nightly has been removed. the bare NVIDIA DLL was redundant and caused export-not-found failures on Proton. The OptiScaler 0.9.0-final release notes also explicitly advise Linux users to delete nvngx.dll when upgrading from older versions.

nvngx.dll is still swept from existing game installs on the next patch or uninstall for a clean migration.

v0.15.1 — OptiScaler 0.9.0-final

Decky Framegen v0.15.1

OptiScaler updated to the v0.9.0 final release (2026-04-01). This replaces the previous pre11 test build.

What changed

• OptiScaler 0.9.0-final bundled (Optiscaler_0.9.0-final.20260401._AF.7z)
• FSR4 upscaler DLL updated to 4.0.2c build
• D3D12_Optiscaler/ directory is now copied to game folders on install and patch — required by the new OptiScaler release for FSR4/FidelityFX DX12 paths
• FGType removed from INI — v0.9-final split this into FGInput and FGOutput. The plugin sets both to nukems on fresh install. Existing per-game INIs are migrated automatically on the next game launch (fgmod wrapper) or re-patch
• Proxy DLL picker — choose which DLL name OptiScaler installs as (dxgi.dll, winmm.dll, version.dll, etc.) from a dropdown in the plugin UI
• Steam game picker — select an installed Steam game and set its launch options directly from the plugin, no manual copy-paste required. Clipboard commands remain available for Heroic/Lutris
• WINEDLLOVERRIDES in the launch wrapper now reflects the actual chosen DLL name instead of always using dxgi

Notes

• This is a pre-release build on the opti-090-final branch. The official OptiScaler v0.9 release URL is used directly; no staging mirror.
• Requires a fresh Install from the plugin UI to pick up the new OptiScaler archive and the D3D12_Optiscaler/ directory.
