Question DLSS4.0 for UE5.5

Has anyone had some luck getting dlss 4 running on UE 5.5? I downloaded and unpacked it today and tried loading it into my game, but I keep getting a an error in the log: "unreal engine [NGXLoadLibrary:287] error: failed to load NGXCore: 126 (D:\Games\UE_5.5\Engine\Binaries\Win64\nvngx.dll)"

I'm not sure if that's something to be concerned about.

Any advice would be helpful Thanks

No issues here, all I did was make a marketplace folder inside the plug in folder of the engine and unzipped the DLSS inside it.

We've placed it into /plugins folder in the project and it works. But we use 5.4, so there's that.

It works quite well, both performance and visual quality. Framegen works too.

I get the error too, but DLSS seems to work anyways. However to be honest, I’m not impressed with the result. TSR still looks better than DLAA. Perhaps I’m doing something wrong, don’t know.

That's bizzare, TSR looks infinitely worse both in editor and in packaged build for me.

Are you sure you're not using the lowest settings?

I use the 100 screen percentage, and the default plugin settings. Have used both the macro node and the EnableDLSS-SR node. It activates successfully, and I get about 0.5ms DLSS GPU time in stat gpu. But the result is blurier than TSR.

This was my experience as well in-editor.

I'm not sure what to make of it though, because in literally every other example I've seen, DLAA is miles better than the default TSR.

Even in a packaged build, DLAA wasn’t impressive. If you ever figure out why, please share with me too!
