Virtual cockpit, volumetric lighting?

[OmniAtlas]

I have heard if you are able to set your aircraft in 'virtual cockpit' mode, you can use 3D or volumetric lighting which has a better effect than the default 2D taxi, landing lights, etc lighting.

Has anyone tried this and experimented?

Thank you.

In P3D2.4 I had merged FMGS with the Aerosoft virtual cockpit (disconnecting all gauges) and that worked great.
I have not set it up yet in 3.1.

I am assuming flight dynamics are not affected.
Was the night lighting impressive?
