Same scene rendered with higher sampling shows smooth edges.
Sampling range: 1 to 16
The mental ray renderer provides five filter methods: Box, Gauss, Triangle,
Mitchell, or Lanczos. Box, the default, is also the quickest. Mitchell is often
the most accurate. The Box filter combines samples evenly, without weighting
them. Each of the other filters uses a particular curve to weight samples before
combining them.

You choose the sampling filter and set other sampling options on the Render
Scene dialog > Renderer panel > Sampling Quality rollout on page 6083 .
