What would be the main reason to be cautious when applying post-processing effects?

Applying post-processing effects involves adding various visual enhancements to a game's graphics, such as bloom, motion blur, depth of field, and color grading. While these effects can significantly improve the visual quality of a game, they often come with a cost in terms of performance. When post-processing effects are used extensively or on lower-end hardware, they can lead to increased render times and reduced frame rates. This can result in a less smooth gameplay experience, which is critical for player engagement and satisfaction.

Developers must balance visual fidelity with performance to ensure an enjoyable experience. Therefore, being cautious about the implementation of post-processing effects is crucial, as their negative impact on performance can adversely affect gameplay, especially in fast-paced or resource-intensive scenarios. Understanding the hardware capabilities of the target audience can also guide decisions on which effects to apply and at what intensity, thereby optimizing performance while still achieving desired visual outcomes.
