Flickering in fluid sim

Support Compositing and Post Processing
1

I have set up a fluid sim, used Set Smooth, Subsurf and wound up the render quality. However my renders have a lot of flicker in the fluid droplets and they still render with the odd sharp, straight edge. How can I resolve this? Would Yafray help?

Thanks

I’m not so much into fluid… But are you sure that you need to subsurf it?
