graphics - Why do games ask for screen resolution instead of automatically fitting the window size?


It seems to me that it would be more logical, reusable and user-friendly to implement flexible, responsive UI layout over a 3d or 2d screen, which can then be run on any screen resolution.


Some modern games auto-detect screen resolution and adjust the game to that, but the option to change the resolution still remains in the settings.


Why is this option there?


My guess is that this is one way to provide older machines with a way to improve performance by rendering less graphics and just stretching them across the screen, but surely there are better ways of improving performance (choosing different texture and model qualities, for example).
