    I've been using a 2011 Macbook Pro and within the last month or two, I've had some pretty bad FPS trouble specifically with Starcraft 2 on my Boot Camp version of Windows 7 Ultimate.

    This is a currently new, brand new reformatted computer.

    I'm running a 2.2 Ghz i7 Quad Core
    4 Gigs of RAM
    200 gigs partition for Windows 7 (I think I have 150 gigs free)
    and a Radeon 6750M, 1 gig card (Catalyst 12.6)

    With this set up, I've also connected it to an external monitor (24" ) displaying something like 1920x1200. However, even when I lower the resolution, to the lowest that it can go - the FPS doesn't go up at all.

    I have ALL my settings set on LOW, actually the LOWEST it can go. (my hardware is supposed to be able to run this at high/ultra, but I want steady FPS)

    During the game, my FPS will start off (vsync unchecked), at around 170~. Within 2-3 minutes, my FPS will start dropping to 120~, and by the 10 minute mark, it gets down to around 30-40. If I go over 120-150 supply, I'm looking at 15-20. And if I hit 200/200, I'm down at 10. When battles happen at that point, it's usually 2-3 fps. This happens in OS X as well.

    Before this happened, I'm not 100% sure what my FPS was, but it never lagged me.

    Now I've done some testing today, I cleaned off all my fans, and the heat sink. I logged into Windows and it's still running hot. In fact, GPU and CPU are at 60 degrees C when it's idle with only monitoring programs open. But, when I'm in the game, it only goes up to around 64-66 degrees C (both GPU and CPU). Also defragged my system last night.

    HOWEVER, when I went into my task manager and stopped explorer.exe, the game ran much better. I'm not too sure why that happened. However, this only lasted a few days, before it just completely stopped working.

    I don't really use my Windows partition for anything other than Starcraft, so I doubt it's something I installed. This problem used to only exclusively be for the North American version of SC2, but now has slowly crept into my Korean version. I've also been having trouble with my D3 (similar just awful lag even on lowest settings) and I honestly don't know why.

    I've been suffering from this for the last few months and it's actually killing me. I have no where else to turn so I hope someone on here can help me!


    after running a 3D Marks just to see if my video card or anything was acting weirdly, (it wasn't - my scores for the 3DMark 2011 was as good, if not better than what the average for my computer should be, and only the PHYSICS score was really low), the FPS jumped back up again. For no reason. Literally didn't change a thing.

    Worked great (200+~ fps for 3-4 days) and now it's back down to 1-2 in big engagements. I can't even do stutter step micro.


    I guess my friend that I asked brought up a good point too. He says he doesn't think it's throttling issue (heat)

    1) 3DMarks score would have been lower, since temperature is gonna be similar, but my 3DMarks score was similar, if not better than other Macbook Pro's

    2) Starcraft 2, is pretty underwhelming as a game in terms of how much power it uses. Looking at my resource monitor while at max out amount of units on both sides, I'm looking at about 1 fps or so, but my CPU says it's using at most, 20-30%, and RAM is 2 gigs free. Even my GPU is at about 30%. When I turn up my graphics from low to medium or anything higher, the amount used will go up as well. So what I'm thinking is that SC2 at it's lowest settings doesn't NEED any more power.

    I don't really know anymore.

    Try turning off indexing of files in Explorer and Windows Search options. I remember having had issues with that.

    Untick unnecessary startup programs in MSCONFIG (start/execute/"msconfig").

    Close any background/taskbar programs.

    Good luck!

    I've closed everything :( and turned off pretty much everything. Nothing seems to be working. My temp doesn't even seem to be that high... The highest it's gone is the CPU is at 70C, while GPU is at around 55-60~
