I decided to re-render this scene from one of the most famus tutorials on the net with the new Vray 1.5. The first thing what i did was to make sure that all textures and shaders are in linear space, then i positoned two vray phisical cameras as the once in the tutorial, deleted all the lights in the scene. Then i created vray sun and vray sky and let them with the default settings.
The settings for the two images are:
Camera
f-number - 8, shutter speed 125, iso - 200 the rest is default.I change the zoom factor and focal lenght to get close to the max cameras.
AA - Adaptive QMC
Michell-Netravali, min. 1 / max. 5
Primary - Irr map - Medium
Secondary - LC
Subdivs - 1200, Sample size 0.01
Interp. samples 5, use light casce for glosy rays ON
And then i hit render and this is what i get. For the two images i just change the cameras nothing else and the result for me is fantastic. Vray is like a dream come true.

Oh look, sunlight being transmitted through glass. ;-)

It's a great test scene, I use it often. Haven't got around to trying it with 1.5 yet though.

Ok, this is going to sound negative, but I don't want it to sound that way...

I'm just curious as to what you've proven here...

Does it render much faster, much better or what...

The lighting setup in the original file is just one direct light for the sun, and thats it, and it was done in a really old version of vray...

It renders faster with better quality and the most important thing is that i spend allmost no time at all to set up the scene for the final renders. I did just TWO test renders one for each camera and didn't have to play with dark/bright multiplaiers, light multiplaiers ets.. So from the moment i opened the file to the final renders it took no more than 30 min. So to be able to set the scene like this that has both interior/exterior in such short time and to get that good results witout having to change anything but the camera i thing it's pretty good. I'm not saying anything bad about the Osmosis tutorial in fact it was wery helpful for me when i was starting with vray. Even now with 1.5 it's still a must read for everybody who is starting with vray.
@manta : about the "negative" part don't worry. After all that's why i posted in the first place to get some valid opinions.

Well, here's what I came up with just doing a straight render, no color mapping or post work, its just one direct light acting as the sun, just as it is in the original scene file, didn't change anything except the glass material which was'nt a vray material, so I made it one, with fresnel...

I guess what I'm saying is...that I don't see that feature taking anymore than 3 minutes off my scene setup...sorry like I said, I don't mean to be a killjoy.
