I tested 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
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)
