  • Perform a clean boot: Disable all startup services besides the necessary Windows apps and drivers. Restart your PC and try playing the game.

2. Close background apps

Having apps running in the background while you are gaming often leads to various game issues. The situation with the Warhammer 40000 Boltgun crashing is the same. This is why you should close all apps before running the game.

💡 Another essential thing to consider is apps that create overlays. Either disable overlays in the app settings or fully close the app. Usually, these are Steam, GeForce Experience, and Discord.

  1. Using the CTRL Shift ESC shortcut, open Task Manager.
  2. Find the apps you don’t need when playing Warhammer 40k in the Processes tab.
  3. Right-click on the app and choose End task.

Warning: Never disable background apps or processes you are unfamiliar with!

3. Verify game files

Corrupted game files have been bothering gamers since the first days of the modern gaming industry. This is why Steam offers an easy way to verify if all game files are where they should be in the form they should be!

  1. Launch Steam and go to the Library.
  2. Right-click on Warhammer 40,000: Boltgun and select Properties.
  3. Select the Local Files tab, and click on Verify integrity of the game files.

4. Disable fullscreen optimizations

Fullscreen optimization is a Windows feature that is supposed to optimize the performance of your PC while you play games or use resource-demanding apps. However, it doesn’t always serve the purpose.

  1. Right-click on the game executable (.exe) file and open Properties.
  2. Navigate to the Compatibility tab.
  3. Tick the box next to Disable fullscreen optimizations.
    Disable Fullscreen Optimizations Compmatibility Tab
  4. Click on Apply and OK.

Extra steps

If you did everything we suggested and still can’t play Warhammer 40000 Boltgun due to regular crashes, try to:

  • 🥵 Check the temperatures: This primarily concerns the GPU, for which the optimal temperature is 85° C (185° F). Ensure proper ventilation and remove dust from your PC.
  • 🛡 Temporary disable the antivirus software: Check if the game stability improves, and if it does, add Warhammer 40000 Boltgun as an exception, so your antivirus doesn’t cause crashes when enabled.
  • 💻 For portable gamers: If you are playing Warhammer 40000 Boltgun on the go using your laptop, click on the battery icon in the taskbar, and set the Power mode to the Best Performance.


Hopefully, you are enjoying the game thoroughly, and the Warhammer 40000 Boltgun crashing is not close to your mind. However, if you still struggle with the game’s stability, comment with additional details, such as when the game crashes and the error code you get.
