A new Fallout 4 mod removes some of the game’s fake light sources and adds dynamic lights for more realistic shadows and visuals at night.

The Fallout 4 Dynamic Lights and Shadows Overhaul Mod from modder ‘Raidenfrank’, is currently in its pre-alpha phase and bugs may occur. In addition, its creator mentions that the mod requires powerful hardware due to dynamic lighting and FPS drops might occur.
