Hearts of Iron IV: How to Remove FPS Limit

This guide will allow you to get rid of a silly refresh rate limit that prevents you from having more FPS in-game.



Have you ever wondered why you can’t have more FPS than 75 in Hearts of Iron IV? Let me tell you briefly, there’s a silly limit in the local settings of the game that limits your refresh rate to 75Hz. Even though you try to change your refresh rate in-game, it won’t be applied just because of this limiter.


In order to get rid of this limiter, you’ll need to reproduce the following steps:

  • Go to Documents > Paradox Interactive > Hearts of Iron IV
  • Edit settings.txt with Notepad
  • Find the max_refresh_rate=75 setting and change the value of 75 to your display refresh rate.
