i have both single and dual computers with maya, both work fine, dual better without any particular fix as such, I just installed it as per usual.??
I have a dual core mac but I cant be bothered having maya on three computers?
what Im saying is I think there is no 'use multiple processors ' in maya. when in dual only 50% of the processor is working during render on mine, as opposed to 100% on single
take it easy and life will be easy
