    Whenever I play with my imac, or my friend mbp w/ ATI, their graphics are so much smoother and etc... how come the uMBP graphics is soo choppy (unplugged)? Ive read that it's the drivers but if it is.. then how come apple hasn't fixed it in the past updates?

    Are you talking about Windows or OS X. The Windows drivers definitely need work, however, many users have used modded drivers to improve Windows GPU performance.

    Cheers,

    I don't know what you are talking about. I mean, I had something similar to that with the 9600GT, but that was before the updated drivers came out. However, the 9400M is used in all of the new Apple laptops, so the driver package should be rather good. I found that it works smoother then the 9600, as a result of better drivers.

    Hmm, I don't see that on mine. I've never used the 9600 under OS X (other than a brief test when I first got it) and can play all manner of HD movies, TV episodes, etc w/o any difficulty. What else are you doing?

    Cheers,

    I don't use expose or spaces. Perhaps someone else can answer you.

    Yeah, I'm using my 9400m unplugged right now and I'm not seeing this chop... I just opened 10 windows and still no chop. Do you have a lot running or something along those lines? I have iTunes, Firefox, Transmission and Reason running and there's no chop here...

    hrm.. by choppy, i dont mean anything serious where youd start seeing lines across the screens but its just the movement of the windows arn't as smooth as other and less advanced video cards..

    the weird part I'm wondering is how everyone whose replied mentioned so problems when this seemed like a serious issue awhile ago

    The 9400m is a low-end 3D solution. When you are not plugged in, the power management kicks in, and downclocks the card so it uses less power. So you have a low-end card running in low-power mode. That's what makes it choppy and slow.
