V-Ray 1.5 and beyond - Being the fastest raytracer on the market doesn’t mean we have stopped optimizing our system. Yes! V-Ray 1.5 IS faster than before with up-to 30% ! Come and see for yourself.

I had the exact same problem, i just went back to version rc5 because i got fed up of the slow render times. It has to be some sort of setting that needs changing to make the render speeds normal again but I simply couldn't find it. I found it very weird how slow the 1.5 final version was compared to all previous versions.

Hopefully someone can explain what to change to make the render speed normal again;)
