Red Dead Redemption II - optiscaler/OptiScaler GitHub Wiki

Version	Optiscaler 0.7.7-pre7
Filename	`winmm.dll`, `version.dll`
OS	-
GPU	-
Inputs	DLSS, FSR2
Settings	-
FG-Settings	If crashing, then try with `FGType=nofg` in Optiscaler.ini (Alternatively if you want to use fg without crashing (might not work for all cases) you can use OptiScaler v0.7.0-pre66 version and change nvngx.dll to winmm.dll)
Known Issues	OptiFG HUDfix might not be working properly, depending on the version
Notes	DirectX 12 is recommended to be used, Vulkan is problematic FSR2 inputs are questionable, Steam version crashes, so disable FSR2 in game settings before adding Optiscaler (or set `Fsr2=false` in Optiscaler.ini) - recommended to use DLSS inputs Use Optiscaler as `winmm.dll` to successfully load, AMD/Intel users also need `Fakenvapi` if DLSS isn’t exposed Renaming Optiscaler.dll to `OptiScaler.asi` and using Ultimate ASI Loader x64 as `winmm.dll`/`version.dll` also works 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* Compatible with Lenny’s Mod Loader Turning on NV Reflex with Fakenvapi can cause stutters.
