I don't think the day/night cycle is too fast, but it is a good idea to set the timing of it.
BUT the night is way too dark!!
The night is unnecessarily too dark but at least I can see something in the vehicle light beam. But there is a small time at dawn when still dark but the vehicle lights already go off, at that time I can see almost nothing even at full backlight, mainly when I play in daytime. It is VERY annoying!!
Developers, please fix this, there is no need to make the night THAT dark in the game. Thank you in advance!
