Is there a way to compensate too-fast viewport moving when game speed increased?

Hi.
By viewport moving I mean when mouse is moved to the side of screen to look around the location. Seems like the amount it moves over time is scaled with the game speed, which looks natural from technical point of view, but not very convenient to use it. Is there a configuration option to adjust it? Mouse sensitivity from options (I'm not sure if it's for this) is at minimal position.
