Which is a good practice for applying post-processing effects effectively?

Limiting effects to essential enhancements is considered a good practice for applying post-processing effects effectively because it helps maintain performance and ensures the visual quality of the game remains high. Overusing effects can lead to visual clutter, making it difficult for players to focus on important elements of the game. By prioritizing essential enhancements, developers can enhance the visual appeal without overwhelming players or negatively impacting frame rates. This approach also allows for a more polished and cohesive visual style, where every effect serves a specific purpose, contributing to the overall aesthetic without detracting from gameplay clarity and performance.
