Hi there, I’ve just been doing some testing with DLSS and it’s hard to tell whether it’s even doing anything in my ue5.3 scene. What I’m trying to determine is whether the performance is increasing or not, and my findings are interesting:
Base settings: TAA upsampling enabled, TAA selected as the Anti-Aliasing method. Screen percentage is 66.
First screenshot is showing 156 fps avg and lesser image quality with DLSS plugin disabled:
The second is showing 151 fps avg and better image quality with DLSS plugin enabled:
You can see that there’s more linework happeing from my post process shader when DLSS is enabled
but I’m wondering why the performance is dropping
I tested without the Post process in a normal scene and DLSS is not improving my performance. I’m also wondering whether it’s necessary to have TAA upsampling enabled, with TAA method selected for DLSS to work. Is this true?
Should I disable them?
Is this the correct way to enable DLSS in my project?
I also have a blueprint setup like this:
I followed the documentation but I just can’t really tell if it working and I expected better performance from using DLSS rather than a decrease.
