So I thought the HDR in Ratchet & Clank was excellent, and Uncharted 4 had a nice upgrade, but then I tried the Witness, which just had the HDR patch release today for PS4/PS4 Pro.
Holy SHIT is what I kept saying as I walked around the island. Maybe 20 times or so in the last five minutes.
Some of the colors and sheer brightness is so crazy that I almost have to squint. The red water/watercolor lake near the mountain is beautiful. The orange autumn forest is insane. Every color pops with such an intense vibrancy that I've never quite seen anything like it. It is amazing. Holy crap. HOLY CRAP. I find myself exploring just to see what something looks like.
I'm using a Vizio P 2016. If you have an HDR TV, you owe it to yourself to buy this game and just see what HDR can really do. Hoo boy. Pro upgrade is nice but 1440p/60 is way better than the 4k/30 mode for sure.
Every game/movie/everything needs HDR support immediately.
