The clock speed is set by the driver inside windows. There are several versions of the 6400M GPU:Įach have a different clock speed. Since we are stuck with using the Radeon HD 6490M GPU, I thought to just optimize that GPU for battery life as other laptops use that GPU with no battery issues. I took a different approach to solving this battery problem and the dual GPUs on the Macbook Pro 2011 model. Anyone tried to do this with any success? If the hardware is there and there are drivers for windows why would it not work on a Mac? If I were to format the system and simply install Windows how would the macbook pro know to keep the integrated graphics disabled? My worry is that if I install the AMD drivers and remove some of the bootcamp ones this might screw up bootcamp if it doesn't recognize them. ![]() I'm specifically referring to the catalyst driver ackage off the AMD website for this graphics card. Since the AMD Radeon 6750 M has graphics switching and is able to perform it with no probs on other non-mac windows laptops I was wondering whether I could remove all the apple graphics drivers and install the default AMD ones. However, my guess is this is done via the bootcamp drivers for windows. This is not a question of which OS is better, they both have their merits. I realise that graphics switching is disabled in Windows and I hate Apple for it, I know they are doing it on purpose. Even playing starcraft 2 on full settings doesn't cause it to heat up to unomfortable levels. For general tasks CPU temperature stays below 70 degrees and the laptop is only mildly warm. I almost never use OS X because I need to do run a lot of windows programs and a lot of statistics in Excel which is disabled by microsoft on office 2011 for mac. Fully charged, OS X says I have a little over 7 hours to run although I've never tried to see if it actually gets that much. I only ran down the full batery in windows and it lasts for a little over 3 hours, depending on how you use it. To answer your question theologos, the difference in battery life is huge. Same problem, and i can't change resolution.Thanks for your comments.
