Kalien79 Level 1 Level 1

I have the 15" Retina Macbook Pro, and I have definitely had issues with framerate in games played on bootcamp windows 7. The game I am testing fps is Rift. I noticed when plugged in, the fps drops significantly compared to when it is not plugged in (on battery.) Running on ultra video settings at 1920 x 1080, when plugged in I am getting between 7 to 15 fps after about 3 minutes of sustained use. When unplugged however I get a sustained 34+ fps.


I installed the two new updates ( OSx 10.8.3 and MBPr SMC Update 1.1 ) in the hopes they would resolve my issue. However I am seeing the same fps problems as before.


Additionally while running the game the fan spins like crazy at all times and the power cord gets quite warm. Upon quitting the game, the fan continues to spin wildly with no end.


Can anyone else reproduce these observations? I had an open ticket with Apple to fix this prior to the update on my machine. I was so excited when I saw the release notes to these two updates as it appeared they would directly address my problems. Unfortunately there has been no significant change. Needless to say, my work order shall remain open...

    Have a look around these forums, Have a search for retina 15 throttling. Since apple did the EFI upgrade it meant that the GPU and CPU start to throttle down even at about 80'c. which is way below the specifiaction from intel and nvidia. the core i7 max is 105'c so why apple decided to throttle so low i dont know. People need report this to apple to make them aware of this issue. i myself have got it. Crysis 3 was playing awfull skipping frames and low framerate after it got hot.


    U can force the CPU to stop throttling using ThrottleStop program in windows. For the gpu i think nvidiaInspector people have used to help them, I still think it throttles tho.


    something i tried was wen in windows on maximum performance setting edit the power plan  to only allow 99% of the CPU. This will stop the CPU from going turbo. This will help the temps stay lower at 2.4ghz. (cuz throttling goes to around 1.3 if i recall, might be lower)

    Buy top mbp with retina and receive 1200 Mhz after 80'C - yeah! SMC 1.1 fixed nothing, or almost nothig - before yesterday update i noticed CPU slow down near 70'C, after - 80'C it's make sense - aha... Thank you Apple for top configuration with lowest power of CPU at high temperature.

    Im surprised no one mentioned this, try resetting your SMC


    1. Shut down the computer.
    2. Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
    3. On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
    4. Release all the keys and the power button at the same time.
    5. Press the power button to turn on the computer. 
      : The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.


    The update I believe was to prevent having to need a reset AFTER, but if you needed it before you updated that might be why its still running bad, hope this helps you out.

  • serjs Level 1 Level 1

    I already reset SMC and PRAM/NVRAM procedures doesn't make any changes after to issue after SMC Update as before.

  • Rokrad Level 1 Level 1

    Will this actually work? This is one of the few suggestions that isn't "reset your SMC and/or PRAM" which does not work.

  • GenuineFake Level 1 Level 1

    I believe I have the same problem.


    Been trying to play BF3 for ages now, the rMBP simply isn't running this game properly even on the lowest resolution and lowest graphics settngs. I've seen people on YouTube play BF3 pretty well on auto and medium settings. I know BF3 on Ultra won't run smoothly, as I've seen demos of that, but I'm not even getting close to medium settings currently.


    I've tried SMC and PRAM resets. Recent SMC update didn't do anything.


    One thing did improve speed for a short while was to disconnect power cord and play on battery - but it didnt last that long.

    Def having the same problem, and running a much lighter game (Fifa 13). Seems like plugging in the charger just generates excessive heat for whatever reason, and that causes the system to throttle down the GPU. Pretty sure it's a GPU and not a CPU issue cuz I'm using Parallels Desktop 8 and can specify # of cores dedicated to running Windows. Been having the same issue running Diablo 3 as well. I love my macbook but it definitely has its quirks when it comes to maintaining performance under certain conditions, which in this case is somewhat disappointing since gaming without charger plugged in means you're pretty limited to how long batteries can sustain you before having to plug the charger back in.

  • Kalien79 Level 1 Level 1

    I have an update. After repeated visits to the Apple Store and calls with support, it appears the problem was coming from the MagSafe 2 Power port. They replaced the port and now all the GPU performance issues, heat issues, and fan issues have calmed down. I am getting consistently high framerates in all my games (Bootcamp and Mac) regardless of whether it is plugged in or not.


    Thanks all, hope this update helps.

  • GenuineFake Level 1 Level 1

    Thanks for the update, this sounds interesting - did they take your machine in and replace just that bit. Tell us exactly how the process was, thanks.

  • Kalien79 Level 1 Level 1

    Well the process was long in order to diagnose and fix...


    At first I noticed the GPU performance drop while playing games in Bootcamp (Win 7). Framerates would drop significantly (more than 80% on sustained use) in games like Rift and Battlefield 3 to the point it became unplayable. At this point the machine was plugged in and I didn't differentiate performance gaps whether plugging in or not.


    First I called Apple Support, who first tried an SMC update on my machine. After that didn't work they sent me to an Apple Store.


    The Apple Store took the machine in and after 5 days replaced the logic board and handed it back to me. They said they found "11 confirmed faults on the GPU". I tested it in store after getting it back and it looked to be working fine (but on retrospect it was unplugged when I tested it in store.)


    After taking it home, I immediately started noticing the framerate drop again. I gave it a few days and noticed the drop consistently. I also then started noticing the power converter was heating up bigtime and the fans were going absolutely crazy. I then unplugged the computer and started to play and noticed the framerate shot back up! I then did repeated tests with the computer plugging and unplugging and noted the computer fps went up to full under battery power and back down to a crawl when plugged in.


    I called Apple again and they for a second time told me to go into the Apple Store. I went in and described the problem and they immediately ordered a new MagSafe Power port. ( The also did tests by using several power cords to make sure it wasn't my cord.) They told me I could keep my machine until the part came, so I took it home.


    I kept using the computer while waiting for the part, then one day I saw Apple released the SMC update 1.1 and Osx 10.8.3. I was blown away! The fix descriptions seemed to directly address the issues I was having! Needless to say I installed them right away and started testing my machine.


    I did notice a slight bump in fps but the framerate drag was still there when plugged in vs not being plugged in.


    Then one day while I was still waiting for the power port part and a few days after installing the SMC update 1.1 and Osx 10.8.3,  the power port just stopped accepting charge completely. My mac was running only on battery power now and was losing charge fast.


    I called Apple immediately this third time and again went back to the Apple Store. They confirmed my computer was not accepting any charge now and they took my machine in again.


    The power port part I had previously ordered arrived and the performed the repair. So now I have a new logic board and a new power port and the computer is running very smoothly.


    Hope this experience helps you. I tried to be as detailed as possible of the process I went through. Please let me know if you have any other questions!

  • GenuineFake Level 1 Level 1

    Thanks for that Kalien, very helpfull!


    One question - when they got the part, did you have to wait a long time or was it done on the spot/same-day? Worried I may not have a machine to work on while it is being looked at or repaired.


    Maybe there is more than just one issue - combination of logic board and magsafe/power - it could be a fault across a lot of MBP's. Not everyone truly games with the MBP's so I doubt everyone will notice this issue.

  • Kalien79 Level 1 Level 1

    Well, once they got the part it was a 1 day wait time.


    Yes it could have been a logic board/power port combo issue. But since i was having the same problem even with a new logic board. I think it was mostly because of the power port.


    Glad I could help!

    Hi All,


    I tried this and it improved my FPS in games yesterday, still not getting FPS I would desire, but its become playable.


    Repasted here from another thread:




    My retina MacBook Pro has had terrible graphics performance problems for a couple of weeks. I searched all over various forums and tried everything: resetting SCM, manually selecting discrete/integrated graphics card, deleting graphics kexts, etc. Nothing helped until I found this:


    Now my rMBP has silky smooth graphics again!


    The directions in that post are a little hard to understand so I cleaned them up here:


    Step 1: Delete system windowserver preferences

    1. In the Finder, from the menu bar, select "Go -> Go to Folder..."
    2. Enter: /Library/Preferences/
    3. Delete the file called

    Step 2: Delete user windowserver preferences

    1. In the Finder, from the menu bar, select "Go -> Go to Folder..."
    2. Enter: ~/Library/Preferences/ByHost/
    3. Delete all files that start with   (On my rMBP, there was one file called

    Step 3: Reset the PRAM    (These instructions are from

    1. Shut down your Mac.
    2. Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
    3. Turn on the computer.
    4. Press and hold the Command-Option-P-R keys before the gray screen appears.
    5. Hold the keys down until the computer restarts and you hear the startup sound for the second time.
    6. Release the keys.


    Hopefully this helps others with bad graphics performance on retina MacBook Pros.

    Dear Kalien79,


    I believe my macbook pro has the exact problem. I have reinstalled my mac os/windows 8 and updated them to the latest versions but I still have the same poor graphics problem. I am going to take my mac to service tomorrow, hoping to get it fix. My mac is also a LG version which has some display problems. I am wondering that after the fix, can your mac run battlefield 3 with consistenly high fps?
