Performance and Optimization Recommendations

[Bcompartment]

Not every user is an expert on Bevy, so I want to open a discussion about the possibilities of optimizing the project.

1. It`s a good idea to give the end user a basic optimization roadmap
2. What features give FPS boost In large scenes, but add overhead in small scenes
3. Basic features list that greatly reduce FPS on Low-End And Mobile Systems

If anyone has any ideas, please join the discussion.
