I'm referring to M11. What do you mean you don't know what they're running them on? They're on dev kits. Sure they have more RAM but that's for debugging, the environment is identical to what they'll be running on when we play it.
Perhaps last year they ran into optimization issues last year which is why you claim the earlier game footage looked more fluid. I don't know. Im just basing it off of the footage I see. Considering its on Youtube which is ****y for playback, I'm impressed.
