Wrapper DLL that can force DLAA onto DLSS-supported titles, along with tweaking scaling ratios & DLSS 3. 1 presets.

The DLSS DLL can also be overridden through this mod, letting you switch DLSS version without worrying about the DLL being overwritten by RGL.

If the tweaks helped improve your experience consider buying a coffee to support future development & help to obtain more games to test with, thank you!

Setting up the mod isn't too difficult, in a nutshell: download the ZIP, extract contents of it to game folder, and use the DLSSTweaksConfig tool to enable your desired tweaks (usually can just enable "ForceDLAA" setting if you just want to force DLAA) - then finally launch the game, and the tweaks you enabled should take effect when any DLSS quality level is enabled in-game.

Detailed setup guide:

• []Download the "1. DLSSTweaks for RDR2" pack from the files section of the mod page.

  []Extract the contents of that ZIP file into your "Red Dead Redemption 2" folder.

  []Ensure that the xinput9_1_0.dll, dlsstweaks.ini & DLSSTweaksConfig.exe files are located in the same folder as RDR2.exe, this is necessary for DLSSTweaks to load in & any tweaks enabled in the INI file to take effect.

  []Run the DLSSTweaksConfig.exe app to open the DLSSTweaks configuration tool, here you can modify all the tweaks available.

  []To force game to use DLAA, just change the "ForceDLAA" setting to True and then save the config, on next game launch all DLSS modes will then act as DLAA instead. (note that this will have a performance impact if you were previously using DLSS, since the game will now render at full-res for every mode)

  []If you're using the Rockstar Games Launcher, you can force RDR2 to use an updated DLSS DLL by using the "Add DLL Override" feature in the config tool, and then choosing a nvngx_dlss.dll that you want the game to use - as long as the DLL is outside of the game folder RGL should be prevented from overwriting the DLSS you've chosen.

  []Many other tweaks are also available inside the INI for those interested, the Usage section below gives some examples for them (eg. enabling the "UltraQuality" setting)

  Note for ScriptHook+Vulkan users: if your game seems to switch from Vulkan to DX12 on launch there may be some incompatibility with ScriptHook, haven't been able to reproduce this on my side yet, but as a workaround you can use the "2. DLSSTweaks alternate loader" release from the files section which uses the nvngx.dll/reg file method.

  To set up the alternate release:

  • []Make sure any files from the first release are removed (xinput9_1_0.dll / dlsstweaks.ini / DLSSTweaksConfig.exe)

    []Download the "2. DLSSTweaks alternate loader" pack from the files section

    []Extract the nvngx.dll / dlsstweaks.ini / EnableNvidiaSigOverride.reg / DLSSTweaksConfig.exe from that pack into your Red Dead Redemption 2 folder, next to RDR2.exe

    []Double-click the EnableNvidiaSigOverride.reg file & allow it to merge in - this will only affect certain Nvidia specific signature checks, not anything to do with Windows itself

    []Now use the DLSSTweaksConfig.exe app as mentioned above to set up your desired tweaks, and then run the game

  • (Nvidia driver updates may reset the SigOverride reg change, recommend keeping the reg file next to your game EXE so you can reapply it after updating)

    Hoping to look into why the main file doesn't work properly with it soon, bit of a bummer since I already spent the past week looking into compatibility issues with other games, hopefully can get it ironed out soon.

    (NOT RECOMMENDED FOR ONLINE PLAY - the way this hooks things is similar to how some game cheats work, is likely to be detected by most anticheats)

    ---

    The default dlsstweaks.ini won't make any tweaks & must be edited first - descriptions of each tweak are available in the ConfigTool and in the INI.

    If you just want to force DLAA, enabling the ForceDLAA option can make all DLSS levels act as DLAA instead, rendering at full-resolution with DLSS applied to it.

    (note that this will have a performance impact if you're currently using DLSS, should have about the same performance as playing without DLSS enabled, but with the bonus of applying the awesome DLAA anti-aliasing on top of it)
