Inputs

DLSS, FSR2 (check notes)

Settings

-

FG-Settings

OptiFG → XeFG (preferred when HUDFix is off), OptiFG → FSR FG

Known Issues

  • Turn on OptiFG HUDFix to avoid interpolating the HUD, needs in-game VSync set to On to reduce flicker

    • HUDfix might not work properly, depending on the version

  • Spoofing for DLSS inputs on AMD/Intel causes weird rendering artifacts/crashes in certain places (like Valentine discoball artifact or broken lights in cities) - fixed when using OptiPatcher - check comment

    • Install OptiScaler as OptiScaler.asi + use Ultimate ASI Loader x64 as dinput8.dll (also works as version.dll/winmm.dll) + put OptiPatcher’s .asi file in a new folder named plugins inside the game’s folder and set LoadAsiPlugins=true in OptiScaler.ini

    • Folder screenshot

    • ScriptHookRDR2 V2's mod loader can be used instead of Ultimate ASI Loader

    • ScripthookRDR2 V2’s overlay might cause crashes with XeFG. To fix that, set this in ScriptHookConfig.ini (located in the game’s folder): 

      [Interface]
Enable = false

[Overlay]
Enable = false

  • Nvidia users may need to remove fakenvapi.dll if Reflex is disabled to avoid unstable framerates

  • Enable Use Microsoft Detours API hooking in RTSS to avoid crashing on startup, also recommended to disable Inject NVIDIA Reflex latency markers

Notes

  • DirectX 12 is recommended (required for FSR4 and OptiFG), Vulkan is problematic

  • Nvidia users may install OptiScaler as winmm.dll or use the method mentioned in the Known Issues section (OptiPatcher won’t be necessary), AMD/Intel users also need Fakenvapi (already included in 0.9)

  • FSR2 inputs crash on Steam version (automatically disabled in 0.7.7-pre12 and above, enable by setting EnableFsr2Inputs = true in OptiScaler.ini) - recommended to use DLSS inputs

  • Compatible with Lenny’s Mod Loader, ScriptHookRDR2 V2

  • Turning on Reflex with Fakenvapi can cause stutters

  • Changing to Fullscreen in the menu or through Alt + Enter causes the overlay to disappear until restarting with Vulkan API
