RT Sample Rate Artifact

[Nearl]

Can someone explain why my sample rate looks like this when I run GPU? What's with the "buckets"?

V-Ray RT 3.60.04, btw.

Are there any artifacts in the RGB. If not, those are quite normal and can be expected in the sample rate pass.

Best,

The RGB looks fine once the render was finished. When it was processing the image those areas were noiser than the rest. Didn't know if I was missing something. Thanks Blago!
