Can't get Nanite to work?

Hello! I am brand new to Unreal Engine, and trying to pull in an asset from Quixel Bridge into the editor. It’s pretty low res/low poly and a little blurry. This asset said it was available with Nanite, and I downloaded it. I’ve also right clicked it in the content browser and enabled Nanite on it, but it doesn’t seem to make a difference.

Am I supposed to do something else to get this working?

Uploading photo here. I have the same low poly / blurry result for any nanite asset I try to bring in from Quixel.
