max_refresh_rate causes the game to stutter

[Lurpsukka]

I have a massive frame stuttering problem in Hearts of Iron IV. I've found the culprit and it's the max_refresh_rate command in the settings.txt file which contains all the graphical settings for the game. The default value for max_refresh_rate is 75 and it causes massive frame stuttering between 59-61 fps. Framerate itself isn't a problem as I have way over 60 fps, but constant stuttering that's caused by inconsistency in frame timing. This is most notable when scrolling the map, even before the game is unpaused. It stutters few times every second. If I change the value of max_refresh_rate to 60, the game runs at 54 fps. I've had the least stuttering with max_refresh_rate=63, but it's still there. I can't delete the value as it'll reappear when I launch the game.

I have no such problem in other Paradox games as there is only refreshRate=60 command in their settings.txt files, e.g. Stellaris, Europa Universalis IV or Crusader Kings 2.

Anyone else got a similar problem?
