I tested the FPS in a deep forest. I stood in one position without moving the camera and not turning on any flashlight, chemlight, torch, etc.
68fps- at daytime (all day)
58fps- on sunset
45fps- at night (all night)
58fps- at sunrise
68fps- at daytime
I thought that maybe it's due to the fact that you added a "personal night light" in 1.02. But no, I caught the moment in the morning when the "personal night light" turns off and the FPS has not changed. Why FPS drops, if even at night there are no shadows from the trees. What's wrong with this game?? (played without mods on official servers)
