I installed Vista Ultimate RTM off MSDN. I noticed the parallels video driver only has 8MB of memory. Vista gives an error when trying to use some of the functions stating the video card is not sufficient. My Macbook Pro has 256MB of VRAM and should be able to support all the Vista functions. Vista also seems to be somewhat slow and unstable. I have 800MB of the installed 2GB for Vista. Anybody else noticed this? Thoughts?
I am running the Vista RTM on a Mac pro, and have not problems in the Parallels VM. However, Parallels does not currently support the 3D video functions necessary for the Aero graphics, if that's what you're referring to. You may have better luck running Vista via Bootcamp, if you want the Aero graphics.
I recomend setting parallels to 500MBs of Ram, and Vista to 384MBs. I was running 512-1GB of RAM for Vista, and I have noticed, that I get the exact same performace with 384MB, but I have more RAM for OS X.
