One example is if using an API that does not have alpha test, you would need to emulate it with discard instructions in your pixel shader.

Being … WebOpenGL ES API call submission is asynchronous from GPU execution. This can lead to scenarios where an application needs to modify a buffer for frame N whilst an in-flight GPU task for frame N-1 still needs to read the previous buffer data. ...

Web22 de jan. de 2004 · Early depth means that the depth buffer is updated before the “texkill” is executed. This means if the fragment passes the Z test, but fails the “texkill” then the depth buffer will contain the wrong data if early Z is enabled. You must perform “texkill” and alpha test before depth test as shown in the OpenGL pipeline.
