Best Vray setting for professional renderings

Hi,
I am working on some exterior lighting projects. Day view. I am using Vray sun. Can you please tell me which settings should I choose from the options below? Client wants much realistic and sharp renderings.

Indirect Illumination slot

from GI engine
Primary bounces : Irradiance map, Brute force or Light cache ?
Secondary bounces: Photon map, Brute force or Light cache?

Vray slot

from Image Sampler
Type: Fixed, Adaptive dmc or Adaptive subdivision?
Antializing filter: Area , Mitchell and there are many more !

If you're doing stills, go for irradiance main, light cache sub. Keep the settings low and do test renders. Increase your settings only enough to get rid of visible blotches and noise.

Start with DMC and use triangle or lancoz for your AA filter if you want sharp images.

As a side note, there's no 1 best setting. As professional it is your job to know the strength of each settings and use them according to your scene. So start experimenting. Render tens and hundreds of scenes and see for yourself.

So you're doing this professionally and probably asking money for it but have no clue how to do it? And you expect us to do it for you?
Nice business model!

Just an educated guess, but have seen multiple Vray renderings refer to primary brute and secondary light cache. Assume that is good for realism, but will probably take more time than irradiance map.

Image sampler - guess that would depend on the scene. Adaptive perhaps better for interiors, while default for exteriors ?

Antialiasing - Mitchell Netravali gives sharper edges than gaussian etc. Depending on the style of rendering etc... no right or wrong per se.
