Thanks for replies, all.
Aware that I should be using a render-farm/workstation and not a laptop! However, compared with Vue, Max and C4d, (and various 3d add-ons), rendering on vegas and premiere doesn't get anywhere close to 100% load.
I would have thought, given my lappie cpu is pretty close to an older i7 920, it would have been more than enough for simple video rendering, despite throttling etc.

Pity, really like the Vegas GUI/simplicity...and I hate the Adobe non-intuitive everything, despite using their products daily for illustrating/prepress etc. But waiting for renders really gets on my ...
cheers
