I think the slow-down you experienced is because of the render priority. See here and here.

Now it's better
Latest demo 2.00 build - 4,8 Ms/sec (benchmark file, PT kernel)

In fact, there is also performance difference between 1.2 and 1.5 and unfortunately 1.2 is faster (especially considering matte objects & alpha output). I`ll upgrade to v2.0 undoubtedly but I`ll stick to 1.21 for the scenes that don`t require new features. (GTX580`s behave reasonably the same but 780`s slow down a lot)
