I belong to those who having frequent crashes although I tested everything to make it more solid. The videocard could be a problem but I can't install another into my laptop. Despite all the extreme stress losing much work/rendertime I still love Vue becuse: 1) The Ecosys; this is really incredible. 2) GI/GR render  option. Making Bryce deserts I went over to Vue to render fat, steamy greenery and jungles :-D ...so I forgive Vue's flimsy performance. (on my not to update laptop)
