    Hi...I'm having troubles with my rMBP mid 2012... In every game i play (Lol ,CS:GO, etc) in the first 10-20 minutes it runs great (60-55fps) but after a while the fps drop very low ( 28,30,39)... What should i do...It s very annoying.. I reset SMC and PRAM but same results. :(... I put the resolution at 1400x 900 and the performance it s the same...

    Is it running hot? If so the GPU will throttle. From what you are describing it sounds the case. running 10.10 or 10.11?

    Which rMBP?? 13 inch or 15 inch with 650M, sounds like it's the 15 inch and it's heating up and throttling back to cope with the heat. Firstly try cleaning all the dust out and seeing how that goes but you may have to get the thermal paste replaced.

    Are those the CPU temps? Make sure you are reading the GPU temps.

    The symptoms, as you are describing them, are exactly what you would expect from thermal throttling.

    Revert to 10.10, as I believe that 10.11 drivers are not optimised for the 650M. As for the thermal paste if you need to ask you probably should seek a professional service or take time out to study wants required.

    Make sure the vents on the laptop are clear ( dont rush and do it badly! Its fine to scratch your nails / cloth in there, but dont do something silly like use moisture trying to clear them) and keep the laptop elevated when gaming (but it on a slightly uneven surface so the edges are off the ground). Let it run and see if it still happens. If it does, you cant do a thing without taking the laptop a part. If that helps, you can probably try to alter the environment enough so you dont need to open anything.

    Try the gfxcardstatus and check whether that happens under intel's card or nvidia's.

    Alternatively, you can try installing nvidia's drivers and see how that goes.

    OSX GPU drivers are notoriously poorly optimised for gaming.

    But how can i use the intergrated GPU ? It changes automatically..
    And what is the max temperature that GT650M can reach ? It's ok 88 degrees in games ?

    You can select the Integrated GPU with the gfxcardstatus app. Just make sure you make the choice before opening the game or any other graphics intensive app.

    I would absolutely open the machine and clear out the heatsink/fan areas. If you've never done so, a loooooot of dust can build up in three years. After a year, my fan vents looked like the dryer link catch after a large load of laundry. It's a 10 minute job to pull the bottom plate, remove each fan and pull out any large dust clumps. You can not get a proper clean from poking around the vent by the hinge.

    Order the screwdriver kit from ifixit.com - it always comes in handy.
