Quote - The stand-alone renderer is also known as the "external renderer".
I use it for almost all my final output. It's a stand-alone application that runs independent of Vue itself, once the render has started. You can work on other things in Vue or even close it, the render will continue to run in the background (unless you close THAT one).
It is much less ressource-intensive than the basic screen render, doesn't require any involvement of GPU and such.
I have the impression that many Vue users are sceptical to this option, but this is mainly due to "irrational" reasons (they don't "like it", they can't see what's going on etc. - some claim the outcome isn't predictable etc.). But I've used it very much, and the result is exactly as it would be if you rendered it to screen. Only that it will allow you to pull off renders that would crash your system otherwise.
Read the manual for more information.

It's exactly what I did to succed to get my final render !
