well i see that you wanted to know how to get the thing on the bottom of your pics to show rendertime and version of vray ur using, press f10 to get ur render settings open then go to the tab "renderer" and at the very bottom should be a title something like so: "Vray
ystem" click on that and look for something called "Frame Stamp" and that will add the little line on the bottom of your renders once the render is done, enjoy!
