I am planning to purchase a Mac mini that is equipped with Intel HD 3000 integrated graphics. I will be using the computer for iphone game development. I will be using the Unity game engine so I need to know something - does Intel HD 3000 graphics support occlusion culling? I know there are some Intel gpus that do not support occlusion culling, but i'm unsure about the HD 3000 - I really need to be sure before I purchase the computer. Thanks.
