Issue with REF Framework: TemporalUpscaler Not Working! (Help Needed)

[JOHNIBLID]

Hi everyone,

I'm facing an issue with the REF Framework when trying to use TemporalUpscaler. The error message I’m getting says:

Backend is not loaded. TemporalUpscaler will not work. Make sure you’ve downloaded UpscalerBasePlugin (PDPerfPlugin.dll) and the corresponding DLLs for your preferred upscaler (DLSS/FSR2/XeSS).

I’ve ensured that all the required files are present in the same folder, including:

-PDPerfPlugin.dll
-ffx_fsr3_x64.dll and ffx_fsr3upscaler_x64.dll (for FSR)
-nvngx_dlss.dll (for DLSS)

However, the framework doesn’t seem to recognize them.

What I’ve Tried So Far:

1-Verified that the files are in the correct folder.
2-Installed all necessary libraries like DirectX and Visual C++ Redistributable.
3-Used the latest version of the REF Framework.

Any Ideas What Might Be Causing This?

-Is there a configuration file I need to edit?
-Could this be related to version compatibility?

I’d really appreciate your help in resolving this issue. Thanks in advance! 😊

Exact same problem here. Have used REFramework before, see the option appear ingame, PDPerfPlugin.dll is in the correct spot, tells me it's missing.

Using the latest builds of both.

I'm having the exact same issue. I tried using the latest and older versions of REFramework, UpscalerBasePlugin and of DLSS. I even deleted the mod files to then copied and pasted them in the game directory again (read that fixed it for someone in Reddit), but still getting the same effin message.

Reading the installation instructions of the UpscalerBasePlugin on Nexusmods, PureDark says that you have to paste the dll of the upscaler in the UpscalerBasePlugin folder. I have no idea where said folder is, though. I tried creating a folder with that name in the game directory and putting a copy of the dlss dll file in there but that didn't work.

Not sure what else to do at this point. Will have to play with FSR2 in the meantime, I guess.

I think I found the solution. You have to download version 1.1.2 of UpscalerBasePlugin. Perhaps this old version will work because Reframework does not support a newer version. Download link:

And make sure to download the latest version of NVIDIA DLSS DLL Download link:

and download the latest version of Reframework that supports pd-Upscaler. Download link:
