I presume you're talking about noise-like speckles.

Generally speaking, there is no way around those speckles except for
shooting more rays. The most simple solution to achieve this is indeed
to use "anti-aliasing" mode 3 and increase its quality settings, but
there are other places to tweak:

- If the grainy speckles appear to be related to radiosity, increasing
the radiosity "count" parameter might be a more efficient way to reduce
the speckles. Note that you can also use the radiosity importance
mechanism in this case.

- If the grainy speckles appear to be related to subsurface scattering,
increasing the subsurface sample count might be a more efficient way to
reduce the speckles.
