Inputs

Settings

OptiFG is very hit and miss in this game, it either works or it flat out doesn’t (from older versions, 0.7-pre66 used to work)

Known Issues

  • OptiFG HUDfix might not be working properly, depending on the version

  • Spoofing to get 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 .asi in a plugins folder and set LoadAsiPlugins=true in OptiScaler.ini

    • Folder screenshot

    • ScriptHookRDR2 V2 can be used instead of Ultimate ASI Loader

Notes

  • DirectX 12 is recommended, Vulkan is problematic

  • Use Optiscaler as winmm.dll to successfully load, AMD/Intel users also need Fakenvapi

  • Renaming Optiscaler.dll to OptiScaler.asi and using Ultimate ASI Loader x64 as dinput8.dll (also works as version.dll/winmm.dll) - most compatible way, needed for OptiPatcher way due to RGL

  • FSR2 inputs are questionable, Steam version crashes, so disable FSR2 in game settings before adding Optiscaler (or set Fsr2=false in Optiscaler.ini, automatically done in 0.7.7-pre12 and above) - recommended to use DLSS inputs

  • If Optiscaler isn’t working (generally Vulkan), another possible way should be renaming Optiscaler.dll to nvngx.dll and using RDR2-NVNGX-Loader with Optiscaler (overlay may not work). - FSR4 Upgrade not supported this way, also outdated thanks to OptiPatcher

  • Compatible with Lenny’s Mod Loader, ScriptHookRDR2 V2

  • Turning on NV Reflex with Fakenvapi can cause stutters.
