Hello everyone, First of all, sorry if this was posted before, I quickly browsed through the last posted threads but couldn't find a match for my question, and since I'm pressed by time, I will ask here : I recently acquired a MBP 2011 model with HD6750 and was wondering how I could swap to the on-die HD3000. I tried using the power options so far, from what I could remember, using High Performance power plan meant using the dedicated GPU whereas Battery Life meant using the lower performance GPU. However, I set the value to Battery life and the game I tried still ran at the same framerate as the case when I was using the Radeon, on High Performance. Any ideas on how I could swap between them in OSX ? On the Apple site it says that the swap is done automatically, but I want the Radeon disabled, for debugging purposes, and can't manage to do so .. any suggestions ? Thanks in advance, and hope to get this issue solved with your help.
