Anyone else have video playback issues with the 9400m?
I've owned an '08 alu MacBook since it came out in October 2008 and never had an issue with HD playback. Only exception is 1080P Flash on sites with lots of other flash and ads. If I use fullscreen with YouTube 1080P for example, it's perfectly fine.
I've got plenty of BluRay rips and videos shot off my GSIII and iPhone that are full 1080P and they play great on my HD monitor and TV.
I've also got an Early 2009 MacBook 5,2 with the 9400m thats less powerful than the one in the Late 2008 (DDR 2, slower bus, slower CPU, less RAM) and even it will play 1080P fine. I tested it with a BluRay rip of Pearl Harbor and it looked great.
NOW, Silverlight is an entirely different beast. That thing will stutter like crazy on just about anything I've found out. Thanks MS, :roll eyes:
I've played some Amazon video on our iMac that will handle it "OK", and it's a 2007 model with the 128MB ATI 2400XT. About the same as the 9400m with that. So then I went to my Dell Precision running an Nvidia GT 630, and it was still stuttering on that! And it'll play most games on high. Same thing happened with a 5770/6770 I had laying around.
It is better on my rMBP, but far from perfect. I'd say most issues are related to inefficient code, like Flash and Silverlight. When it's H.264, or most any local file, it's fine.
The reason I finally upgraded to a 2010 MBP, then my rMBP was because of the GPU. Mostly with Aperture and using a 1080P monitor. Resizing windows, scrolling heavy pages, etc was getting a little long in the tooth, but it wasn't so back on Snow Leopard. I do think with newer versions of OS X, it's gotten less optimized for older hardware. Sad that it's the norm, but it always ends up that way. How tech works.
