DLSS4 Framegen seems to not be correctly functioning for Unreal Engine 5.7 (downloaded from NVIDIA DLSS | NVIDIA Developer)

Even from sample project it doesn’t work.

Acknowledged, I’ll pass it on and see if there is some known issue.

Thanks for the quick feedback!

Quick sanity check.

Did you make sure there is no interference with any leftover code from your own update efforts of the plugin that might cause this?

Thanks!

Yes, it’s simply the extracted version of the plugin and the project is inside the zip. It’s also not working on a fresh 4060 laptop

Thanks!

I received quick feedback:

They’re running it in PIE mode in editor viewport. FG does not engage when in that mode. They need to be using Standalone Game Mode or PIE separate viewport mode. Please refer them to the documentation where we explain this. It is in DLSS_FrameGeneration_Reflex_DynamicVibrance_UE_Plugins_Guide.pdf Section: Tips and Best Practices - Point 5.
This is also specified as part of the project settings → Plugin Settings → Streamline where it allows enablement of FG in editor using those two modes.

Hopefully that helps.

Oops! My bad! (clearly an RTFM moment! And funny enough i also red the updated pdf but skipped exactly that part )

If i play standalone the sample project works.

In our project (5.7 with latest DLSS) in a packaged build the issue persist also on a build and standalone.

I’ll try to build the DLSS4Sample project (shipping) and investigate more also on our project to understand where’s the issue.

Otherwise i’ll mark your answer as Solution. Thank you!

No worries.

The issue with packaged builds is something that was discussed here in the forums before I think, but I am not sure whether that was ever resolved. If it persists, please let me know.

I marked your answer as solution, in the packaged build of the sample project it works but in my project it doesn’t work (the framegen), it must be some misconfiguration in my project. Plus in my project i also have FSR4 and XeSS (i tried already to disable them to check any conflict but had no luck)

Once i got it working i’ll update here anyway, it might be useful; the really strange thing is that i had FS4, XeSS and DLSS4 working (with framegen) in UE 5.6
