(using latest AE CC2014)
I have a MacBook Pro Retina Mid 2012 with 2.7 Ghz Core i7 processor 16GB memory Nvidia GeForce GT 650M 1024MB processor, doing some heavy AE renderings and just realized that this machine says it has 8 Cores? I'm had not yet turned on Multprocessing in Preferences Should I be?
Should I leave 1 or 2 cores for other applications?
RAM allocation per background CPU is defaulted set to 3GB
Also for Adobe Media Encoder: in preferences under Video Rendering /Rendere it is set at Mercury Playback Engine GPU Acceleration (OpenCL) is that the best config for this computer?
How much ram?
The best settings depend on what you are working on. Here are mine for a nearly identical system:
It's usually best to keep memory blocks in 4GB blocks. If my workflow is more in other apps I'll switch out other apps to 8 gb if things start to slow down. Because of my usual project settings I keep MP turned off on this machine, but for some projects I'll turn it on. If you decide to experiment to MP then keep an eye on the Actual CPU's that will be used and make sure the numbers add up. Other applications and Actual Cores should add up the the total in your system.
