In Elden Ring's Field ReShade, you can choose between the 3 different version for your game: Composite, Svideo, and RGB. Each one of them makes your game look like it's a PS1 game running on a CRT TV.

Composite: Full CRT effect with flickering and everything
Svideo: Slightly better colors than composite and no flicker for a cleaner image 
RGB: Best colors and sharpest image of the 3

Elden Ring's Field ReShade is a very useful tool for all gamers, especially those who play on a CRT TV. It will help you to improve the look of your game.
