    Hi,
    I have a macbook pro with the following specs:

    Processor 2.2 GHz Intel Core i7

    Memory 4 GB 1333 MHz DDR3

    Graphics AMD Radeon HD 6750M 1024 MB

    Software Mac OS X Lion 10.7.3 (11D50d)


    I have tested the graphics performance with:

    Need For Speed Carbon (Macintosh Edition)
    Need For Speed Shift
    Need For Speed Shift 2
    Need For Speed Undercover
    Need For Speed Pro Street



    And all of them can only be smooth at low - mid settings.
    I thought with the CPU and GPU I have, I should be able to run these games at max setting with no lag. If I am running pro street it even lags with medium settings a little bit. I have Windows 7 ultimate and Mac OS X on the computer.
    I not really a gamer (I do music production), but I expected better than this from a computer so powerful. Is there any way that something could be damaged? Both OS'es are freshly installed fully up to date. Pro street was from 2007 (5 years ago) and a macbook pro with an AMD Radeon HD 6750M 1024 MB struggles to run it? Something can't be right?

    The 6750M is not a strong gaming card, and using it OSX means even greater performance degradation.

    5 year old games however should be fine in Windows.

    Thanks for your reply.
    When you say "and using it OSX means even greater performance degradation" what do you mean? OS X is slower? But the 6750M is a full 1GB, how could it be weak? Is the AMD Radeon HD 6970M from the iMac on a whole different level? I am disappointed in the GPU...

    Thank you for your reply MrCaff, but I don't understand how to read that chart? I'm not really a gamer, so I'm not to knowledgable about graphics. I really only use Logic pro etc...

    ----------

    NFS carbon in Mac OS X runs well on OK settings but in windows, all the games run worse. On my windows, it only is able to use 2gb of ram out of my 4 for some reason - would that make the performance worse? Or is it that windows is so, so much slower than mac?

    ----------

    I did believe that the GPU in my macbook pro would be able to run ANY game at MAX setting and get very high fps. Does CPU make much difference for games? Does SSD make a difference for them? More RAM?

    1GB is how much memory the video card has, not a measure of its performance.

    But I must admit that in my windows partition the games run bad, I mean they even sometimes crash and just have a lot of lag...

    ----------

    What measures its performance?

    A number of things, the quantity of memory being simply one of them.

    The quantity of shaders cores, their clock speeds, memory bandwidth, etc. One cannot judge a graphics card solely on the amount of memory it has.

    There's nothing in the Card's name that is a direct indicator of performance. Card manufacturers do that on purpose.

    You'd have to go to a third-party resource for that.

    I have a 6770M in mine. It certainly won't scream on the most recent games, but it works just fine on older stuff, or newer stuff with lower settings. The 6750M should be about the same.

    AtomicGTR tell us a little more about your system.

    At what resolution are you running the games? 1080p on 17" or 15" with something lower. or non native 1024x768

    What does the Windows Experience Index say? The numbers that go from 0-7.9 in your system settings. Especially the GPU score.

    Are you running bootcamp or in a Virtual Machine? I have never heard that it can initialize only half the RAM if you run it native.

    Mac games all suck but NFS shift should run on high with some 30 fps fluently not ultra. As for the newer once I don't know any benchmarks and don't have the games but I expect at least middle should be possible. I think something with your setup is wrong answer the above questions

    Thankyou mumford and dusk007.
    I run the games at the full resoloution and my screen size is 15 inches.
    The overall windows experience rating is 5.5

    The graphics rating is 6.9
    The gaming graphics rating is 6.9
    Processors rating is 7.3
    Ram is 5.5
    HD is 5.9


    I'm running in boot camp.

    Why do apple put bad GPU's in their computers?

    it's a good video card for a laptop, but OSX is really bad for gaming. Use windows 7 via bootcamp when gaming if possible.

    The 6750M is near the top of the middle class of notebook GPU's, and should run current games at mid to high settings fairly well.

    Maybe you should try updating your GPU drivers if your games aren't running smoothly in Bootcamp.

    I have another problem. And it does it on EVERY need for speed game (That's all I use). After some time playing the game, the computer will just go to sleep and crash the game. Why is that?

    ----------

    How do I do that?

    well, i run battlefield 3 on boot camp, on the same mac as the OP at HiGH setting without problems. also bad company 2 on high runs smooth as butter. so the 6750 its a good gaming card for a lap top. not the best but better than many others :D

    The computer sees only 2 gigs of ram out of 4 ? That's (mainly) your problem. Try installing a 64 bit version of Windows 7. You are running a 32bit one ( aka x86)

    You're thinking of the 6770m, the 6750m is a fair step down.
    Neither are good cards, the 6770m is at the bottom-end of mid class GPUs.

    The 6750 is a low end dedicated card and as a result won't provide very good gaming performance on medium to high settings. That said, it's not a terrible card, Apple just doesn't choose their components with gaming in mind.

    To the OP: Here's a great link for deciphering the naming scheme on ATI cards http://en.wikipedia.org/wiki/AMD_Radeon

    Wow, so I spend 2000 pounds and I get a Early Learning Centre GPU... Very dissapointed - No wonder gamers love windows! Well, I'm not a real gamer so it doesn't matter to me, I use my computer for logic and sibelius. Would the 3.4Ghz i7, 32gb ram, 2gb GPU, SSD iMac 27" be able to run NFS at full settings? Even though I think Mac OS X is far superier for what I do (Audio), I think the hardware is very overpriced. Still though, for audio, I would chose a Macintosh any day.

    The 6770m is just a slightly over clocked 6750M.

    You're right, I was thinking 6570. The 6750/6770 however are still poor GPUs when it comes to gaming. Not bad by any means, but not good enough.


    Seems like you picked the right machine for your needs. Yes, I hear many people say that OSX is best for Audio and Video work. Gaming has to come second unfortunately. You don't see many people buying Macs solely for gaming because that's not what they're good at.

    I'm actually kind of shocked at the people dissing this graphics card. I have found it to be very good - if you know what you are doing. I do not use the stock driver that comes with Bootcamp (just awful), I tend to tweak the game, and then tweak Windows 7 for the best gaming performance.

    For example, Skyrim with setting maxed runs great on my MBP.

    For me, I do the following:

    -Windows 7 Ultimate 64bit
    -16 GB of memory
    -Disable the swap file
    -I use the AMD beta drivers (modded)
    -I wrote a script that stops any unnecessary servers and exits any apps that are not needed.
    -I rarely use the AMD OC tool.

    YMMV, but I have had great success doing this.

    I know what you're saying, but it's not quite that simple. Firstly, Skyrim can run "great" at 25 fps, but racing games like the OP talked about will only be running well if they're at 60 fps.

    Also, keep in mind that Skyrim isn't the most graphics intensive game out there either.

    Hmm interesting.
    I can run GTA IV and Mafia 2 and medium to high settings without a problem.
    Never tried racing games but these work fine.

    Unless you buy a gaming laptop, you get a mid range GPU in a laptop - in expensive ones that is, the cheap ones ship without GPU. Mid range usually means that you can play current, graphics intensive titles with low-medium settings, and older games or less graphics intensive games with high settings.

    I don't know if the NFS series is particularly demanding, but most people seem to be happy with the gaming performance of the 2011 MBP models.

    Most people prefer windows for gaming because most games need it to run, and for multi-platform titles, the performance is usually better on windows. The other advantage of course is that there are much more options to choose from on the hardware side, including dedicated gaming laptops with desktop CPU and GPUs. Most non-gaming laptops have weaker graphics than the 15'' and 17'' MBPs though!

    That performance seems a little weak. I have an old 24" iMac with a 1920x1200 display and a GT120 with 256MB of ram and it can still play NFS Hot Persuit decently. I would expect a 6750 1GB to be fine.
