Weird flickering shadows

I’ve been trying to make this as a personal project, but whenever i try and implement lighting of any kind, it just gives these weird flickering shadows. How do i fix them, while retaining a decent lighting level here?

you’re using a compensation of 11. it’s very likely that your lights are not bright enough.

that leads to noise on lighting.

if you have only one light, in a game with a dark aesthetic, then global illumination really helps, as otherwise the scene can look very dark (maybe that’s why you’ve raised the exposure).

otherwise increase the ambient light.
