The CUMULUS and CUMULONIMBUS especially. People keep forgetting that clouds look different from above than from below. The sky should also appear very dark-blue while looking up and out while at flight levels too.
I challenge anyone in here who keeps disagreeing to post pics of RW conditions to what we see in the sim. The youtube video above does a great job of explaining lighting options.
The problem is that if we all just throw our hands up in the air and settle for what we have, nothing will get changed. I’m happy to have what we have, but it needs to be much, much better. Atmospherics for high-level flying are way, way off.
