Hi--

I have the eval version of Parallels and have successfully installed WinXP Pro (SP1) on my Mac Pro. Cool. I installed my old copy of 3ds max 6 and fired it up--more cool.

However I noticed that when using Parallels/XP/3ds max on my Mac Pro I only see 1 core being used. I've rendered some pretty heavy scenes in 3ds max and the system doesnt use more than 1 CPU/core.

I seem to remember that WinXP had to be configured for multiple CPU's--can anyone shed light on how to make Parallels/WinXP use more juice?

Thanks much

Its not a windows xp issue with the cpu but how parallels is setup and to date AFAIK there's no way to configure parallels to use (or allow xp) the second (third/fourth) cpu on your system.

Thanks for the reply. Wow--that's a huge limitation. Guess I'll be holding off on Parallels till they support multiple CPU's.

Off to try BootCamp....

thanks again--

I'd give parallels a try - depending on what you're looking to do. all things being equal its pretty perky. Just because the windows environment within parallels doesn't see the second cpu, parallels does use all resources including multiple cpus.

I use it parallels to connect to work, use office apps and IE and to be honest its pretty quick,
