We The Players Winners - November/December. The mod has receive a new update, which now let's you rebuild the Witcher fortress that was compeltely empty until now. A new game is suggested for using v5, or at least a clean save away from any interior, city, or town if using RLO v4.1.1 or any other existing non-RLO save. There is light where there is suppose to be light and not where there is not suppose to be light. Luminosity since it is compatible with everything/can be made compatible with everything with a few drag&drops in 圎dit. Some mods have alternatives such as textures, weathers and lighting, but I've found this combo to stay similar to Vanilla with minimal performance impact.
Realistic Lighting Overhaul v5.0.1 - BAIN Installer by Mertz. I agree, I feel like my lighting and weathers look better in LE at times. From what i've seen none of them look all that great in SSE.
