I'm using cs 5.5 and After Effects. When I enable mutli processing in my 6 core processor, I get no speed improvements when playing back in the AE timeline. Is this multi processing only good for rendering? 99% of the time I'm working on comps, and not rendering, so I am HOPING the multi processing will be for that.
Sorry for the newbness
Is this multi processing only good for rendering?
Yes, it is - if at all. There will always be scenarios where it won't even be used like temporal effects, GPU effects or specific CoDecs that are not MP compatible. That's just how it is and you have to learn these things and work with them, not hoping brute force would solve problems.
