I'll be honest, Los Santos doesn't look just spectacular with the snow, but I will tell you what does... Blaine County.
When I first loaded online yesterday (when it actually worked lol) I spawned in Los Santos, and I wasn't too impressed. Don't get me wrong, it looked great, better than last gen, but nothing to make you say "wow!" What really impressed me was when I ventured into Blaine County.
Walking up the "nature trail" behind the Observatory was impressive, but when I went up the hill at the end of the trail, my jaw dropped. Snow everywhere, trees were covered, just the whole area looked great. I snapped some screenshots using the built in screenshot function on the Playstation 4.
For my grand finale, I present to you "The Sunset".
Sorry for the overload of pictures, I'm just a sucker for detail.
P.S: I have a video of me walking up through the nature trail, to the top of that mountain if anybody wants to see it.
