Problems with flickering in turntable renders

Hi all,
Just wondering if anyone has solutions to my flickering issue.

Basically I have sculpted a model in ZBrush and rendered a turntable using Best Renders. The result is flickering. I have tried double my document size and it seems I am not getting any better result.

Is there any place I could up the resolution/samples to help reduce flickering issue?

I am using ZBrush 4R4…

thanks so much in advance.

are you using BPR or Best Render?
Is the flickering in the lights, shadows, ao, etc?
