They already are. Ratchet is targeting 30fps but then offering a 60fps lower res/graphics settings option. And I'd predict that'll be the standard once next gen hits its stride. It won't be a repeat of last gen where the CPU was a bottleneck for 60fps regardless of resolution and graphics settings, so there can always be a 60fps option even if it drops to 1080p. 120fps fans may be disappointed though.Long may it continue.
Anyone else worried that devs will start targeting 30fps again at some point?
