No spoilers, but I watched a few very clear vids of the PS5 version in the other spoiler/leak thread. So I'll report here what I saw in a general way with zero spoilers.
To be honest there really wasn't much of anything in those vids that I consider spoilers. Just don't watch them if you don't want to see anything before launch.
It was the PS5 version and there does seem to be a performance mode now because it was definitely running at 60fps. Some dips here and there. Not a perfect lock but overall very smooth and completely playable. Someone claimed it was running at above 1080p but below 1440p. I can neither confirm nor deny. And if this was with all the same graphical settings as the base PS4 then I'm impressed with the graphics. It looked really nice with lots of detail everywhere IMO. I think this all must be before the day one patch too.
The vids were just free-roam, no story, no cutscenes, just wandering around the streets and back alleys of Night City at night for a few minutes. It started with some driving in your car. You can talk to pretty much everyone and they will have something simple to say to you as they walk by. There were vending machines and shops. There really weren't any spoilers in the vids, they just let you take a look at some of Night City and it looks great. Lots of ambience and verticality. Stuff is happening everywhere, above you and below you. There's alwasy a ramp or stairway to goes up and down in every direction. It's obvious to me now that it will be possible to just get lost in Night City and admire how beautiful it is and how much work must have gone into crafting this world. The NPCs are wandering around with many unique behaviors and I can believe they have their own 24 hour cycles of activity. You can even encounter crimes taking place and it's your choice to intervene or not. You'll be able to spend hours doing just this without even doing any of the story and you'll enjoy yourself. I know I will.
I also saw a vid of flying in a corpo flying car. Part of this was already shown in official trailers. The city looks amazing from the ground and from the air and I can't wait to explore it myself. The background music was suitably oppressive and bleak. Reminded me of the new Bladerunner.
I'm gonna try not to go into that leak thread anymore, but I'm so hyped and there's still DAYS until release! Hnnnnngggg!
