Same problem – new issue for me.
I have 16GB of ram 2×2.26 quad core xeons and no other applications running
I’ve tested rendering comps that have one layer of pre-rendered video @ HDTV specs 1260 frames – Still have an insane pre render wait.
After effects will show up as not responding for about an hour before starting w/ or w/o Multi Processing
This makes no sense to me as I’m getting these issues both at home and work.
I tested a simple solid in a comp and that rendered super fast.
Again this issue started about 5 days ago
