100% CPU Usage Fix

Crash At Startup Fix

Hearts of Iron 4 players are reporting that the game crashes at startup. Here are a few fixes that’ll help you resolve the issue.

One reason for the game to crash at startup is the lack of admin rights. Right-click on the game’s exe > Properties > Compatibility tab > check “Run this program as administrator”. Apply the change and the game won’t crash at launch.

If the issue persists, then the issue might be an outdated OS. Update your OS to the latest version, especially, if you are using Windows 10. Games and apps require the latest build of Win 10 and an outdated OS can cause Hearts Of Iron 4 to crash at launch.

Using third-party monitoring software like MSI Afterburner or GeForce Experience can cause the crash at startup. Disable any third-party utility you are using and the game will stop crashing at launch.

Black Screen Fix

Black Screen at launch is a common issue with PC video games and Hearts Of Iron IV is no exception. Players are reporting they get a black screen when they launch the game while they can hear the audio in the background.

To fix this, launch the game and when the black screen appears, press “Alt + Enter”. The game will go into Windowed mode and will start to display. Go to the video settings and set a resolution that is native to your display and you’ll be able to play the game in fullscreen.

Low FPS, Performance Fix

Performance issues are common among PC video games. Hearts Of Iron 4 players are reporting low FPS and stuttering issues with the game. First, make sure you have installed the latest GPU drivers and there is no background process using too much of your GPU, CPU, or HDD.

Open Nvidia Control Panel > Manage 3D Settings > Program Settings > select the game. Set Vertical Sync to “On”, set “Power Management Mode” to “Prefer Maximum Performance”, and set “Texture Filtering- Quality” to “High Performance”. Launch the game, disable in-game v.sync and the stuttering and low FPS will be resolved.

If the game is still stuttering then follow the steps mentioned above but set Vertical sync to “Fast”. This will not only fix stuttering but, will also provide a potential boost to performance if you have a moderate enough CPU and GPU.
