Unreal 5.3 DLSS not working

Development Rendering

I’ve just installed DLSS for Unreal 5.3 via downloading it from: [Deep Learning Super Sampling (DLSS) | NVIDIA Developer…]. I’ve followed the instructions and enabled all DLLS plugins. I’ve also copied over the UI widget from the sample project into my own one.

However, when I run the game, the HUD looks like the following:

NOTE: This probably has to do with the ± 100 errors the widget is giving me.

Note 2: When I run the sample project included in the DLSS package, everything seems to be working fine and I can see widget with DLSS being enabled and I can change the settings.

Note3: When I run ‘stat gpu’ in the console, I can see the DLSS computing, however there is no difference in performance:

So is it working then if I can see it pop up here? And if so, why do I not see any performance gain?

Note4: I also typed ’ r.NGX.DLSS.Quality 0’ in the run command, but still no performance boost.

Any help in this regard will be immensely appreciated.

Thank you for your time

DLSS Must be enabled in the Project Settings to work in PIE, if you have already done that try these two console commands:

r.NGX.DLSS.Enable 1
r.ScreenPercentage 67

generally in my experiance DLSS performance boost that you might see is at par with using unreal native TSR and setting a lower screen percentage so dont except a miracle.
