Looks like GTA V with mods.
I don't get everyone being so excited about the graphics.
Maybe this are console players who haven't seen GTA V on PC but graphics wise it doesn't seem like a huge upgrade.
Sure I'm excited for the story and new possibilities like being able to enter more buildings and maybe more activities like in rdr2 but graphics wise it kinda looks "normal".
The animation system is on a whole other level, the hair simulation is leaps and bounds above anything you can mod into V, it's obviously using a modern PBR rendered and a ton of other things that makes both just night and day.
Go watch V's trailer (which for the time was incredible for an open world game) side by side with this and open your eyes.
