I like the new lighting system in general but it sure produces some weird things. Earth-like worlds look like icy planets now, they are just so bright, almost white. Space stations are almost like beacons on their own, they blind you as you arrive to them. I feel that the brightness* is a bit overdone in places. I'm sure they will tone it down a bit in the future. The biggest problem is not having multiple light sources. A planet's dark side will be pitch black even if a secondary star is right above it. It's just unrealistic.
*Edit: It may not be brightness but dynamic range, or something like that.
ED supports multiple light sources already. The problem was (and now is
even more evident due to the new lighting system) that ED supports only
one star light source at a time. The remaining light sources are allocated to galaxy & nebula lighting, ship, SRV, station lights as well as building and megaship structures lights, and passive reflection from planetary bodies and planetary rings which of course are a lot. However I believe that ED should be able (without increase in hardware requirements) to support
at least two star light sources. This transition effect that was implemented back in 2.x is totally immersion breaking. The light & shadow generator is traveling magically from one star to another - first time I saw it thought it was a mysterious (alien?) stellar phenomenon..
I am using reshade and although I have yet to play with 2.3 due to the server issues (I preferred to just download the update and wait a few days for the servers to stabilize), I feel that I will need to re-tweak various parameters & values of it. It took me weeks to achieve a nice balance between light, color and shadow based on the old lighting system. I can't go through this again...
