Render Scale parameter in Built-in Pipeline

Hello there,
I want to create an old effect, like a retro effect and I found this great parameter in the Universal Rendering Pipeline settings asset, called 'Render Scale'. By reducing its value to let's say 0.5 it already gives an impression of a retro game.

The only problem is that I don't want to / can't use the Universal Rendering Pipeline, but instead I use the Built-in one, but I want to do the same thing. Specifically reducing the Render Scale. The good thing about this parameter is that it gives the effect and has a tremendous performance increase. So it's really beneficial to the game I'm creating as it contains a huge map.

Is there a way to do this? Thank you

 

Yup, there is a way to do that.

I think this would work too.
But you'd have to change
Resolution Scale > Fixed DPI in Player Settings.
