New MacBook Pros With Auto Graphics Switching Not Switching Properly?

Apple's new MacBook Pros feature automatic discrete graphics switching like NVIDIA's Optimus, but is based on their own solution and it turns out it may be a little bit buggy or just not working too well. When a MacRumors forum member discovered how to detect whether the integrated or discrete graphics, Engadget put this to the test and found out issues ranging from the notebook turning on the discrete graphics for applications that do not need it to the fact the notebook wasn't turning off the discrete when it wasn't needed. - But it gets worse.
