Since installing 5 after upgrading from 4, I have found a few times when initiating a render it is unusually slow, as if it's using the lowest amounts of cores/threads and therefore falls asleep as if the CPU isn't active. Also, I can tell this is happening as the fans don't kick in. It just took an hour to get to SL4 of a render, which I cancelled and restarted and then got to the same state in 7 mins.

I'm not aware I'm changing anything that I shouldn't but any ideas why it sometimes does this?

nic.
