What is the purpose of adjusting the Field of View (FOV) in Unity?

Adjusting the Field of View (FOV) in Unity is primarily aimed at enhancing the visual perspective of the game. FOV refers to the extent of the observable game environment that is seen on the display at any given moment. By changing the FOV, artists and developers can create different visual effects and perspectives that dramatically influence how players perceive the game world.

A wider FOV allows players to see more of their surroundings, which can enhance the sense of space and immersion, especially in first-person or third-person perspectives. Conversely, a narrower FOV can create a more focused view, which can heighten tension or direct attention to specific elements within the scene. Each of these adjustments can significantly impact gameplay experience and player engagement.

The purpose of manipulating FOV aligns with artistic choices and game design principles, rather than the technical aspects of audio levels or polygon counts. Additionally, it does not directly correlate with scripting performance, as FOV adjustments are primarily about visual presentation.
