GAME · RED DEAD REDEMPTION 2 · CHECKED ON DRIVER 621.14
NVIDIA Profile Inspector for Red Dead Redemption 2
RDR2 ships DLSS, and players often swap DLL files or use DLSSTweaks to get a newer model. NPI can force a newer preset through the driver without touching game files: set the DLSS override rows in the RDR2 profile. NVIDIA already ships a 24-setting profile that turns ReBAR on, so forcing ReBAR changes nothing. We could not compare presets or confirm the override works in RDR2 without a GPU. Red Dead Online is a separate case for anti-cheat.
What NVIDIA already sets for RDR2
The profile named Red Dead Redemption 2 covers RDR2.exe and Red2.exe.

Why RDR2’s DLSS can look soft or shimmery
The game shipped with an older DLSS model, and that is why players look for newer ones. We did not check the DLL version in a game folder, because we have no install, so we do not say which version it is. Preset differences are in DLSS presets.
Force a modern preset with NPI
Open the RDR2 profile
Select it in the profile box. NPI’s profile covers the game process
RDR2.exe, not the launcher. Add a game explains exes.Turn on the override
Apply, restart and check
Click Apply Changes, restart the game and check with the DLSS indicator. The full guide is the DLSS override page.
Whether RDR2 accepts the override is not something we could test. NPI issue 485 reports a profile bug in version 3 involving RDR2 values. COMMUNITY · issue 485
NPI, DLSSTweaks or DLSS Swapper
NPI changes a driver setting. DLSSTweaks loads a wrapper DLL, and DLSS Swapper replaces a DLL file. See the comparison for risks.
ReBAR and RDR2
RDR2 is on NVIDIA’s ReBAR list and the profile already sets it. Players copy its Resizable BAR values as a reference. Read the ReBAR guide before forcing anything.
Red Dead Online
Undo
Set the override and preset back to Off and N/A, then apply. Undo and reset has the steps.
Questions people ask
How do I use DLSS 4 in RDR2 without DLSSTweaks?
Open the RDR2 profile in NPI, set DLSS - Enable DLL Override to On and pick a Forced Preset Letter, then apply and restart. We could not test that RDR2 honours it, so check with the DLSS indicator.
What is the best DLSS preset for RDR2?
We have no RDR2 comparison. The presets page explains what each is. Test them in a scene with foliage and fences, and judge in motion.
Can I turn on ReBAR for RDR2?
NVIDIA's profile already sets it, so forcing it again changes nothing. Whether it is active depends on your BIOS.
