PS4 Alpha release live-stream replay:
A couple notes: This guy is new to AC. Some tracks are laser-scanned, some not. The game appears to be using only a small amount of Anti-aliasing, which is probably how they are keeping the game running well on PS4. It also looks like shadows, reflections and textures are less complex.
I think I like the UI so far, even though I'm sure it will change. Hopefully, a lot of the interface aspects of this port will be available on the PC version later as an OPTION only. For instsance, I'd like to see some of those HUD elements added as standard "apps" within the PC version of this game.
