This may not apply in all games but I’ve played some games with day/night cycles, but overall the experience I got was that most of the time, when during night time, the game had FPS drops lower than day time. For example, I played NFS Heat and I get around 30 fps at day. When I play at night, for some unknown reason for me, it drops about 5-10 fps at most. It’s a very shallow question I know, but I would love to get an answer from y’all since this has been one of those things you can’t really shake off your mind

I would guess it has to do with the number of light sources in night vs day. Daylight is usually just a single sun source, whereas the night scenes have a ton of different color neon lights and stuff. They *should* bake a light map so that its less intensive but I think those games like to use a lot of dynamic sources that will change reflection bounces based on movement in the scene rather than being statically painted. You should be able to lower graphics settings to get less dynamic lighting (look for a setting like Global Illumination or something along that line)
