Widget Animation jerks while playing in game

[Slavq]

A similar thing is happening in 5.5. UMG animation is smooth in UMG editor (and in Play in Editor), but choppy (looks like low fps) in Standalone mode and packaged game. Related topic:

As in the title, it happens with all widgets. It’s like UMG animations have less FPS in-game, even if game is running at 60 FPS… I’ve had the same problem in 4.9, so it’s not a matter of 4.10. It’s especially noticeable when doing small transforms (e.g. angle change) over longer time, for example rotate from 0 to 10 degrees over 1 second. Any clues how to fix that?
