What does the bucket size mean in Xnormal?

Zepic

Say I'm rendering out a 2048x2048 texture in Xnormal; would the largest bucket size (512) be my best option? Do I get a better fidelity if I use a smaller one?
I'm a bit confused on what exactly the bucket size means...

Bucket size is the size of the little box that moves across the image and renders bit by bit. When it comes to render speed size doesn't matter when you're not using multiple computers to render. I usually leave it on default. Quality wise it shouldn't matter.

It's just the way xN splits the job for parallel computing the rendering.
For normal rendering, try to keep to 32x32. If you set it too low the multicore-rendering will be inefficient... and if you set it too high the render process will make the CPU to access the RAM a lot because the L2/L3 cache will be saturated.

For network rendering, try to increase it a bit ( 128x128 ) so the cost of moving the packets by the network will be amortized.
