What's the use of playing Fortnite in Stretched?

To the people who have been playing this game for a long time or who are very familiar with Fortnite:

What does it bring or what are the benefits of playing Fortnite in Stretched - ie 4: 3?

My other question is, if you change in a 4: 3 resolution, does this automatically change the DPI (mouse sensitivity) in Fortnite?

It does not change anything except that it looks kke although the game already is

My opinion.

The character models are getting wider, which makes it easier to hit opponents or their heads

Streched brings a lot, it looks kke, but you have more FPS, with me it is for example the Eg I have 150 FPS, 240 FPS, and also the hit boxes are larger, which makes some easier to Aimen.

The DPI changes only if you do something to it
