Sorry, I wasn't clear - from what I know, on the consoles only few Unreal games on one specific console made it to 60fps. I could be wrong, and have old information, and yes this greatly relates to older Unreal engines, and from what I've heard (over and over from people working with it) it was the script language and kismet (maybe I'm confusing terms here) that was the limiting factor.

Now I'm a generalist, that ended up as tools engineer, so I might be talking complete non-sense, but again when I've talked to anyone from my previous studio or others that was the overall sentiment - Unreal can't give us 60fps unless Epic are directly involved and custom version for a game is done.

(Obviously you can do 60fps always, but it may not be up to the visual quality of other 60fps games).

Looking at UE4 and blueprints, it seems that they've understood their weak point and worked aggressively on fixing it. So it could be that UE4 would deliver 60fps just fine matching visual quality of other products at the same fps. (aaah, now someone would add - what about resolution? heh, I dunno - I think upscaling is just fine, but then you have all these crazy journalists digging up... frame rate is much more important though)
