This app enhances the overall Meta Quest experience.  The choices it provides to the user in enhancing the game via graphics, maintaining a steady frame rate, and even enhancing the battery life allows a variety of different experiences for games and other sorts of apps.

For myself, it is primarily used to enhance the graphics, but you've got to be aware that increasing the graphical 'beauty' will have 'costs' elsewhere (e.g., some impact on battery life).

I enjoy the ability to create your own profile from games that may not be supported, although it takes some learning to get things balanced (e.g., it looks beautiful but has a lousy framerate).

This is a 'go to' app for myself every time I play.  Well worth the cost.
