Did you set up the DLSS settings in the level blueprint? The settings you make in the editor won’t apply to runtime mode.

Additionally, are you running your scene in full screen, game mode in the UE4 editor when you check the frame rate? A smaller window in the editor will of course render at a higher frame rate, since it’s also rendering at lower resolution.

Finally, you shouldn’t run LiveLink mode if you need performance. Always run Cooked mode since LiveLink mode as a substantial performance impact. LiveLink is only intended for when you want to make adjustments in the fly when setting up your scene. 

Yes i set dlss in blueprint but with aximmetry it only has a slight performance gain and only on quality, anything outside of that has no effect the second i boot up aximmetry.

Also, i have to have the unreal pie window in focus otherwise im quaranteed that the fps will never go past 25fps in aximmetry, and this is with "reduce cpu load when not in focus" unchecked.

Cooked content doesnt seem to have that big of a performance benefit atleast in my case.

Im gonna have to experiment to figure out what could cause this weird behaviour as i havent seen any other similiar posts with issues like this.

Edit. checked one of the performance issues by using two monitors, aximmetry on one and unreal editor on another.

When switching focus from unreal editor (by clicking window) to aximmetry, fps will instantly drop by atleast 10-30 frames.. its absurd and have no idea what can cause something like that

Also if i set aximmetry framerate to 50, it will always be stuck on 25 fps and never go past that, the only way to get it past that is to set framerate to unlimited..

The performance drop you’re seeing when switching focus is an UE4 setting: https://answers.unrealengine.com/questions/474269/keeping-editor-running-as-normal-when-not-in-focus.html

Sti, like I said, don’t expect performance in LiveLink mode. It’s not intended for running in real-time. Cook the project, quit the UE4 editor and switch to Cooked mode in Aximmetry. 

What resolution are you running in? You should see higher performance gains for Balanced mode with DLSS when running Aximmetry in 4K. 

Also try switching to the latest Game or Studio driver, depending on what you currently have installed.

I agree with TwentyStudios.   You should never use LiveLink mode in production.   Issues like this will happen if you do.   Cook the project and EXIT Unreal Engine.

TwentyStudios would you say it would be better to run the scene in 4k with dlss rather then in 1080p with dlss ?

DeataProduction: No, I’m saying that you should see higher performance GAINS when using DLSS and rendering in 4K. Some performance issues aren’t bound by rendering resolution, and DLSS won’t help with those issues. DLSS simply allows you to render at a lower resolution while giving the appearance of rendering at a higher resolution.

Did switching to cooked mode and exiting the UE4 editor help with your performance issues?
