If post-processing effects are not visible in the Game view, what is a potential solution?

Ensuring that post-processing is enabled on the camera is crucial when effects are not visible in the Game view. Post-processing effects in Unity require a specific setup where both the camera and the post-processing volume's settings are correctly configured and enabled. If post-processing is turned off on the camera, then none of the effects such as bloom, depth of field, or color grading will be rendered, resulting in a lack of visual enhancement in the Game view. This step is essential for developers to verify, as it directly impacts the visibility and application of those effects.

While other potential solutions could involve hardware performance or global settings, they do not address the root cause regarding the camera's configuration itself, which is where the application of post-processing effects takes place.
