Hi Damien,
For atoms/bonds/ribbons the relevant parameter is "subdivision," which can be controlled in the  Effects panel or with the "set" command, e.g.:

set subdivision 5

It is also changed by presets.  More subdivisions may be slower to render, but in your second picture the parameter looks extremely low, much lower than the default.

More details and related parameters for surfaces are given in the Image Tips section on smoothness:

I hope this helps,
