we are always encountering a similar problem. When we are doing our compositing with footage still being rendered at the same time, After Effects slows down so much that it is not usable anymore.
The footage comes from our network, it is not local. Like AE would scan and reload footage the whole time, but switchin g off Auto Reload doesn't really help.
Any help or ideas?
Have you tried it with CC 2015? (Make sure, if you do try CC 2015, that you don't let it remove your old versions as it defaults to do.)
Yes, unfortunatly the same, like in all previous version also.
