I used my Monitor brightness settings and NVIDIA Control Panel and the nights are are just too dark and makes the game unplayable, I feel like they should make visibility during nights better because you shouldn't have to skip nights,.

I totally support this. The nights being more dangerous is not the issue. I love the more dangerous nights. I'd prefer them to be even more dangerous. But daytime is too damn short. Like, ridiculously short. Then you sleep and have 1/4th of the "daytime" either dark and rainy or dark and foggy or all three. It's supremely annoying.

If hte game seems to dark you might need to adjust the gamma setting on your driver. This is a different setting than brightness and should probably be the first one you try adjusting.

I had the same issue with the view in game being almost completely black at night, even with a torch it was like walking in a black fog. After i tweaked the gamma a little it improved significantly. There was a thread awhile back requesting an in game gamma setting for just this reason. Seems that on some installs the game is just too dark at times.

As to the day not being long enough I have to dissagree, 21 minutes is a reasonable amount of time, with the 9 minut night it make a "day" a tidy 30 minutes IRL. And it's also plenty of time to get enough resources to craft a hammer and axe then build a basic shelter with a bed and fire.

This is of course just my opinion based on being used to a 21 minute day, First survival game I ever played was Mincraft which had a 20 minute day, though MC also had a 20 minute might. if your used to games having longer days I can understand it might be bothersome

your monitor probably isn't properly calibrated to begin with

Check you're monitors RGB range is set to full (0~255) and the same for Nvidia control panel under adjust colour video settings (advanced).

I'd appreciate some different rate of time settings but you can sleep through the night. A camping mechanic to do that out in the wild would be good.

I can agree that days are.. seemingly shorter than they should be.

Considering you can sleep through the night, I would personally be okay with longer days and nights.
