You can also enable caps key, this will prevent the comp to render in the picture viewer.
With 4gb of RAM it’s useless to use multiprocessing…. If you want to speed up render a lot, you’ll need a new PC. This is the only way…
Edit: Usually we, authors, trying to make rendering time as less as it’s possible. So if you considered to speed up render time by turning off layers\dof\blurs\etc., you’ll lose original quality and this isn’t an option i think…
Has anyone mentioned rendering to a fast ext. drive / RAID?
Away from the, OS, AE and included assets.
Works for me.
Worth disabling any grain effects as well, they can really increase your render times. Also, empty your AE cache and a reboot always helps if I’ve been using AE continually for quite some time.
