Why is the actual rendering time shorter than the set maximum time

Question: Why is the actual rendering time shorter than the set maximum time

Reason: The rendering will stop because the image has reached the set noise value.

When the rendered image reaches the set width, height, resolution, noise value, and rendering quality, the rendering will stop.

Solution:

Controlling by Noise Value:

If the actual rendering time (to meet the noise setting requirements) is shorter than the set maximum rendering time, the rendering duration will be the actual time required to meet the set requirements.

Controlling by Maximum Rendering Time:

If the actual rendering time (to meet the noise setting requirements) exceeds the set maximum rendering time, the rendering will stop after the set maximum rendering time.

Note: It is not recommended to set the noise value to 0.0001 (the minimum limit). In this case, the theoretical rendering time will be nearly infinite, and the rendering duration will be controlled by the set maximum rendering time.
