Well, this stability discussion is always a little difficult. Stability depends on so much system issues - beside the stability of the application itself. I can say that Vue 5 for me is a smooth and easy to handle application. Of course i miss some Pro features but i honestly prefer Vue 5 most right now - from all versions i have. Of course too there are some minor things that need to be checked and corrected. As always when you make such a transition from one version to the next one. Look at Windows itself - how the transition from Windows 2000 to Windows XP was and still is. I did a little comparison about rendering times. As everybody can do it themselves. Create scene in Vue 4, load it in the different versions, render it and see. 800x600 pixel image ........... V4 ................. V5 ................ 4 Pro preview ............................... 46" ................. 52" ................. 49" final .................................. 3'13"............... 3'30"................ 3'36" broadcast ........................... 8'17"................ 5'31"................ 7'18" superior ............................... -.................. 12'05"............... 12'38" ultra ................................ 12'55"............... 22'04".............. 36'06" Maybe you try it out for yourself. As war2 said, with the increased light settings you can change the rendering times easily - but the image quality too. Fact is, that i render some of my old scenes in Vue 5 with global illumination (mostly) again right now and replace the images in my gallery. I did three already and will do more over time. The quality of the Vue 5 renders is so much better with the new settings. Mad Mouse II in my gallery is an example for such a re-rendering. Ok, you don't see the old version, but the new one looks terrific (i think).

One day your ship comes in - but you're at the airport.
