That's actually what I expected, but I couldn't find any reference. So, I defaulted to the optimistic, but probably wrong stance hoping that someone would correct me. Thanks!

This means that, at least on traditional forward rendering GPUs (Nvidia, Adreno), overdraw is full cost even for pixels covered by opaque views. Do the PowerVR chips still get effectively-zero opaque overdraw from their tile-based-deferred-rendering approach?

Meanwhile, I'm not totally clear how hidden surface removal works on Mali chips. They use TBDR, but still recommend drawing front-to-back to avoid overdraw http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc....
