even remasters of 360 games ran at 30fps on last gen.
Assassin's Creed 2, 30fps,
Far Cry 3, 30fps
Batman Arkham Asylum... fucked up 40fps or something
you literally can not compare this. this is not even remotely like last gen and it has nothing to do with crossgen or remasters as they also didn't boost framerates last gen. cross gen games like Assassin's Creed 4 still ran at 30fps on all systems.
this is the first generation in ages where almost everything is 60fps. 30fps is the weird uncommon outlier and that has never been the case in recent history, not on PS360 nor on PS4/One, not even with cross gen games often not even with remasters
