Spoiler Alert! This is gameplay from Chapter 5, so if you don't wanna spoil anything, don't watch it yet... Having said that, it probably won't make much sense anyway. So, watch it for the sheer visual spectacle, I guess.
Also, if a base PS5 can do this, I don't think I need any better systems for the foreseeable future.
If possible, please watch this on a HDR screen, and get ready to have your mind-blown!
