How to Speed up Hearts of Iron 4 – The Basics

The first things you are going to want to do when attempting to speed up your game is to turn off a few options that may be adding to the lag.

Firstly, you are going to want to turn off the day and night cycle (discussed how to later). This option changes the maps appearance from night to day, but also causes some lag.

Furthermore, you will want to disable Fog of War, which adds a cloudy appearance above other nations.

Even though this looks somewhat cool, it really doesn’t do much except slow your game down.

To do both of these these, you must click the buttons, located in the bottom right corner of the screen. There should be various buttons located here, click the ones located left most.

Alternatively, you can hover over the buttons, and one should say ‘Day and Night Cycle’, and the other ‘Fog of War’.

Within the Graphical Options Menu

To continue to make HOI4 run faster, you will have to enter the graphical options menu. To do this, you will have to:

  1. Click Escape
  2. Click ‘Game Options’ Button, located in the centre of the screen
  3. Click the ‘Video’ Tab

Here, you can modify various aspects of the game to improve the performance. Lets go through the various things you are going to want to disable within this menu:

  • Disable Cities: The first thing you are going to want to do, is to uncheck the ‘Cities’ option. This will remove cities from the map visually.
  • Disable 3D Trees: Next, disable 3D trees. These really don’t add anything to the game, as they are just visually appealing, and not strategic.
  • Disable 3D Buildings: Same as 3D trees, these don’t add anything to the game, and are just visually appealing.
  • Disable 3D Units: Again, just visually appealing, not strategic.

Those were some of the minor adjustments you can make — but there is more. Here are the 4 main settings that you are going to want to turn off, if you want to make HOI4 run faster:

  1. Disable High Quality Pixel Shaders: This just improves the graphics quality.
  2. Disable Reflections: This will remove the reflection on the water.
  3. Disable Weather: This will disable the visual aspect of the weather.
  4. Disable Shadows: Disabling shadows will remove the shadows of various objects and things, which will significantly improve performance.
