Latest wip Rendered view looks grainy and poor performance

Rendered view is graniny and is less responsive then in the last wip where it was working quite nicely. This wip is a step down in performance as the scene is now grainy and when I rotate a scene its goes into the cycles dust mode, very annoying. Please leave this work like it was it was really working well now it looks like a bad cycles viewport.

@3dsynergy Could you try the latest WIP? What do you think?

Edit: Whoops, my brain thought it’s Wednesday today. You are going to need to wait a day until we release the new WIP. Sorry!

Okay, let’s try again. Could you test the latest WIP and tell me what you think?
