well i got a brand new MBP, had to wait for a bit on a custom order, i upgraded to the 2.8 or what ever. so i don't have an older MBP to compare, i have a MB the last gen, so cant compare to that card.. so yesterday i was making a gallery of pics for my mum to view of my daughter, i had switched to the NVIDA 9600M card the other day to see if i was going to have any problems with it. well i made a simple pic gallery using a lightbox. you know when you click on a pic the screen fades to black or almost black and displays the picture you clicked on. well with the 9600M my screen would glitch out every time i clicked on a pic of my daughter. what i mean by glitch out i guess was instead of a smooth fade to black i would get blocks and squares of my website moving all around the screen then the pic would finally pop. this is no good, so i switched to the 9400 and tried the lightbox and it works perfect.
so today i updated to 10.5.6 and switched over to the 9600M. sucks you got to log out to do this but at least you don't have to restart. well tried the lightbox and the upgrade seemed to fix the problem. as per noticeable comparisons between the old MBP and nu MBP can't really comment. so far so good as far as quartz goes. chris wood had sent me a file he made called massive clod. i couldn't even view it on the MB but views fine on the nu MBP. maybe some one could clear up something as per quartz and the gpu is concerned. in my hardware profile for the MBP graphics, with the 9600M selected it says that "quartz extreme" is not supported. not sure actually how the gpu works but if quartz extreme and extreme 2d are not supported then i am not utilizing any gpu ? so the graphics processing or core graphics stuff is being processed by the cpu ? why would apple ship a computer that does not support their own technology. i have a television plugged in right now and it says that the tv is supported but the internal monitor is not ? so it seems that quartz extreme needs to be run off the pci or something not sure how the internal monitor fits into the pci equation, but i think that would suck of the stand alone laptop could not utilize the gpu ??? so those are some things. that and my screen goes black sometimes. not to sleep, just black. i can remote on to it fine but the internal monitor goes black from time to time. its less than a month old, i still have apple care, and accidental protection looks like i might need to utilize one of those options. usually takes a few years for for something to break on my apples. told my self i wouldn't buy 1st gen MBP, but thought the nuGen was just an update and not really a whole new system ??? lets hope 10.5.6 helps On Thu, Dec 18, 2008 at 1:28 AM, vade <[email protected]> wrote: > Actually, I think you are right, I think this was mentioned in another > forum about that issue.
