Look at the attached image. As you can see at the bottom, different buckets have different amount of noise. I have never seen this before.. The scene is simply setup with a couple of vray lights, low qmc, irr and lc settings for testrender. One pc was used with 8 buckets.
What are your AA settings?

Default DMC with full adaptive amount
You can try increasing the minimum rate for the dmc image sampler to 2 and see if that helps.

I think I run into the exact same problem the other day (using maya). Increasing the min subdivs for the adaptive dmc solved it in my case.
Is this a known issue or a problem in newer builds? Have not seen this before either…
Unfortunately I don’t have the scene anymore so I can’t try and increase the min rate, but I do know that the only difference between this scene and so many before it in previous versions of vray is that now I was playing around with the Directional value for the lights, which didn’t exist before 2.0.
