Hi there everyone.

I have noticed that the mac mini only has 64meg of vram available for graphics when running OSX.

The other day I decided to have a go and instal XP via Bootcamp. To my suprise I found out that I had 256 meg of vram available from the 2 gig I have installed in my system

can anyone please tell me if there any way to increase the amount of vram available in OSX.

It seems like it would be a good idea to have more available if you have more system memory

    The amount of VRAM that's been allocated in Mac OS X will change depending on your video needs. By default, the minimum setting is 64MB but it should go up if you start doing video-intense work. This way, more RAM is available to the system when its needed, rather than having 256MB taken away completely.

    Is this really true? The VRAM will somehow increase as you need it? I have not gotten a Mac Mini because I need more than 64 mg of VRAM. If this can be expanded I would become a mini customer. Can you explain in more detail?

    Most Macintosh computers have dedicated video RAM. The iBook G4 has 32MB of of VRAM, for example, that's soldered in to the logic board. This can't be changed. The new Intel-based Mac mini is different. It shares the system RAM with the integrated Intel video system. So, by default it actually takes 80MB of system RAM and assigns it to the video system. However, just like Mac OS X can assign system RAM to your application as it's needed, it can assign video RAM as it's needed in the Intel-based Mac mini. Check out the Mac mini Technical Specifications.

    What, exactly, do you "need more than 64 mg of VRAM" for? Chances are, if you have a specific program that requires more than 64MB of VRAM, it will also have specific requirements for the video system. The Intel GMA950 video system included with the Mac mini may not meet the minimum requirements of your application, even if it can share more than 64MB of system RAM for video.

    The reason I am asking is because the specs dont make it clear as to what is actually available. Apples specification on one hand say 64mb of shared memory and on the other hand say a minimum of 80mb

    Recentley I downloaded the Motion 2 compatibility checker from apple. The result stated Motion 2 would instal on my computer, which it did but application quit after the initial screens. The GMA950 graphics chip is suppossed to be CI & QE so the only reason I could come up with was the limited graphics memory.

    I don't expect wonders from my mac mini but it would be nice to know that its got some future proofing other than just running the ilfe suit.

    Unfortunately the mini will NOT run Motion 2 and it is still unclear as to whether it will run the rest of the Final Cut Suite although it does appear the only problem application is Motion.
