RHI 2.6.4

v2.6.4

Changes

• DLSS Super Resolution, Ray Reconstruction, and Frame Generation version combos now include NVIDIA Override as a selectable option. Choosing it writes the driver's "Latest DLL" flag to the game's NVIDIA profile, equivalent to enabling "DLSS — Enable DLL Override" in Profile Inspector. Selecting any other version or clicking Restore DLSS/SL clears the override. NVIDIA Override is also available as a default in Configure Defaults (applies via Quick Apply) and as a selectable option in Batch Deploy.
• Added support for per-game custom Engine.ini files, hosted in the rhi-repo engine-files/ folder and referenced by game name in the manifest. When set, RHI fetches and merges only the keys in that file instead of the standard HDR key set — allowing precise control over what gets written for games where the full set causes issues.

Bug Fixes

• Fixed NR Cost Scaler and RTX 40 MFG Unlock not detecting new releases mid-session — Check for Update and the 4-hour timer now bypass the ETag cache and always fetch fresh release data.
• Fixed NR Cost Scaler and RTX 40 MFG Unlock not auto-deploying updated files to game folders after a new version is staged.

Manifest Updates

• Black Myth: Wukong — custom Engine.ini file applied on UE-Extended install/update (writes only r.HDR.EnableHDROutput=1 instead of the standard key set). Standard HDR and LUT controls in the UE-Extended cog are disabled for this game.
