Lumia 920 very laggy after Cyan (8.1) update

[WPCentral Question]

Black was very snappy, but Cyan just feels sluggish.
Is it supposed to be this way?
Is it possible to revert the update?

Same here, L920 worked fine before update, now everything is laggy, even scrolling down tiles or app menu isn't smooth anymore. Soft reset didn't help, I don't want to do hard reset now (hey, that's not Android, right?) can some other L920 owner confirm such behaviour? Maybe that's how MS tries to force us to update phones...

Yap same here. While scrolling down, there seems to be some sort of a delay on bottom of the screen. Doesn't look right
