Dear AMD dev team,


I think that i read somewhere that the GCN architecture does a hierarchical depth test in hardware. I can't find the reference at the moment, so please correct, if my remembered false. But if its true, is the hierarchical is used also when only point primitives are rendered with OpenGL, or is at this case direct depth test is used?


It would be great if i can get a short statement of a amd developer, because i need to know this for my bachelor thesis.


with best regards,
