    Specs:

    Graphic/FPS issues
    Sorry in advance if this is the wrong Forum or if it's been answered before.
    ---------

    I have a problem that happens basically all the time. When I first start playing any sort of graphic-using program (from major fullscreen games to flash games to iWeb) it works fine for awhile. Not too long after starting it -usually about 5 minutes or so after- the fan starts going and it gradually gets louder, during the time that it's going framerate on my computer is REALLY slow.. this persists for about 15-20 minutes usually and it will suddenly go back up what it normally does..

    I know it's capable of playing these games at 60 FPS because that's what it starts out with, but then it goes down to between 4 and 10 FPS during the time that the fan is going. After it goes 'back up' it stays around 30-40 in what I'm usually doing.

    ALSO - I should add, this isn't a problem I experienced when I first got it or for a long time after that.. I think I first started noticing the problem around the last OS update.

    You're going to need to provide more information about your machine and software prior to someone being able to give you a good answer.

    Things like:

    Version of Mac you have
    GPU you have
    RAM you have
    OSX Version you have
    Software you have running in the background
    My Macs: Late 2013 rMBP w/ 750m, 16Gig ram; 2013 Mac Pro 6 core w/ D700, 16Gig Ram; Mac mini G4, 1.25 GHz, 512m ram (server); Late 2011 11" MBA, 1.8GHz i7, 4Gig Ram, 256Gig SSD, HD3000; Powerbook 12" G4 1.33GHz running Linux; Apple TV (1080p version)

    Provide the information @Nethfel asked for, and at the least add your Mac information to your profile so that we can quickly check that information..

    Remember a Mac isn't like a console where just saying you own a PS3 or XBOX 360 immediately tells others about the devices capabilities..you need to elaborate to get any useful answer back..

    Regards

    It's not a problem with the screen, that much I do know.

    The next time it happens do this:

    Go to Applications, Utilities. Open the Activity Monitor.app and look to see what's consuming the CPU and memory. Copy it down best you can and post it back here.

    A quick note about flash... Any kind of flash intensive game or graphics display, (video, etc) will ramp up the fan as flash taxes the system fairly heavily. In fact, you may see the frame rate going up and down during that time. Your GPU should be able to handle most, but not all graphic intensive games and displays. It's normal to see some degradation during that time.

    Was this happening before you upgraded your RAM to an unmatched 3GB?

    I've checked this before, it never uses up more than 300MB of memory or so & 40-50% CPU.

    I took a sample from the program that was running through activity monitor and the line "AssertandCrash" came up a lot

    Specs:
    1.8 GHz i7 MBA 11" OSX 10.8.2
    temperature monitor to see if everything is working - not a video monitor
    Apple - Downloads - Dashboard Widgets - iStat Pro
    It should tell you fan status, etc and what is heating up.

    And yeah - any flash will kick up the temp/fans.
