For me it was just the running,it looks weird,far from real. Everything else is amazing in my eyes

Stop spreading fake info if you don't understand the thing. You can extract google maps data, but it's terrible, it works for an amateur flight simulator, but that's it. The game it's done with unreal engine and when you use unreal, you can use megascans since they bought the company some years ago, which is basically thousands of assets scanned in high resolution, like a f*cking wall that is 70gb (or lower resolution versions) and shaders or textures to use it wherever you want. That speeds up the process to create a map in barely no time because you don't need to create the thing, I think it was still on unreal 4 that some guy did dust 2 long in a couple of hours using that method, blocking the walls and adding assets and textures from the megascans library. youtube.com/watch?v=hi7A6D0TDfQ If there's no interaction with the environment or it doesn't leave bullets or whatever, is basically because the guy didn't do it on this demo or has no clue how to do it or whatever, but not because it's a "photo". Light is really well done and has a small scenario, but that's what the new games would look, Cyberpunk with the overdrive mod that uses path tracing looks amazing and it's already out there to try with a massive map and a lot of assets and characters moving around, you have those unreal 5 demo tests to try too if you computer is powerful enough
