How do I change the "3D resolution" of the engine?

Development Rendering

So I need to optimize my game and I really like pixelated looks.
In fortnite, I found what Im looking for.

As you can see, the performance gets optimized by the pixelation/resolution, but all tutorials online only show post processing pixelation and i don’t think that’s the same thing.

Any ideas on how to create this optimizing and pixelating render setting?
