Frame generation doesn’t work

strange, it works on my project and others that i’ve tested
please note that there might be other issues related to that

I am sharing the screenshot. Unfortunately, I could not run frame generation whether DLSS was on or off.

Sorry to sound silly but how do I get this overlay up that I see in screenshots ? sorry if I am being silly still fairly new to ue

Have you got an RTX 4000 series card?

i’m not 100% sure but i think you might fix it by put in your project’s Plugins folder in Streamline/Binaries/ThirdParty the same content there was in the original 5.4 plugin

that’s a third party binary/binaries that i can’t actually compile (i don’t have that source code)

in this case i think we have to wait NVIDIA to release the official plugin :(
as i said my version is not meant to be production-ready

You can use the “BPW_NX” widget in version 5.4 by migrating it. It is available in the sample in the official dlss download plugin offered by Nvidia.

Has anyone tried the solution for 5.5? If it worked, can you share the edited files? Cause I tried fixing it & it didn’t work. And there’s no official release date for 5.5 support it seems.
I just need it for the Movie Render Queue.

Having DLSS for 5.5 would be great along with RR. It’s been years now since RR was reveled with cyberpunk and for whatever reason it’s not still accessible with Unreal.

Hey there!
Your file totally worked! Thanks! But I’m getting this dark scene when using DLSS with Path Tracing.
Is this happening because of the unofficial DLSS file? Or path tracing doesn’t work with DLSS?
(Sorry I’m new to this stuff, couldn’t find the answer anywhere else)

& these are my render queue setting components. Am I missing something?

Anymore news on when we can expect DLSS for UE5.5? Thanks paolofalomo meanwhile!!

You can use Ray Reconstruction in Unreal since the beginning, you just have to download the DLL file ‘nvngx_dlssd.dll’ on TechPowerUp, and place it in Plugins\DLSS\Binaries\ThirdParty\Win64. Now it will work in Unreal.
You can try it on my Itch.io demo

Wow and this really works? Are there any commands I need to add to enable it? Also is there a way to get dlss to work in 5.5?

Yes, it really work, you can try on the demo like I said, you don’t have anything to do outside of enabling it trough Blueprints or CVars.
And to make DLSS work in 5.5, just scroll up and you’ll see that someone posted an unofficial but working DLSS version for 5.5… (here)

How do I install that RR and dlss rework to my engine exactly?

You know that I explained the exact steps above, you just need to follow them. Everything you need to get it working is already written there…
You just download and install the unofficial 5.5 plugin like any other plugin, and follow the step I detailed above for RR…
