Update Your Drivers

Kerbal Space Program 2 is released in a good condition. If you meet the minimum requirements of the game, it’s likely that your outdated graphics driver is the main reason why Kerbal Space Program 2 is crashing. We highly recommend getting the latest update for your PC. You can visit your hardware manufacturer’s official website to get the latest update for your device.

Manually downloading and installing drivers for your PC is time-consuming. For some, updating drivers may be a little bit complicated. For those who want an easier method, we recommend trying IObit’s Driver Booster to automatically download and fetch the latest and needed driver update for your PC. In our case, we used Driver Booster to update and fix the crashing and performance issues in Kerbal Space Program 2. You can follow the steps below on how to use the software:

  1. Download Driver Booster.
  2. Once downloaded, install and run the software.
  3. Click the Scan button and let Driver Booster scan any outdated drivers on your PC.
  4. If the software found any outdated driver, click the Update Now button located on the upper left of the window.
  5. Wait until the Driver Booster finished the driver download and installation process.

Note: Your PC may restart several times depending on the drivers that are being updated. Worry not, as this is a normal process for the Windows operating system.

After the driver update completion, try running Kerbal Space Program 2 and see if you still encounter the issues that you have earlier.

Verify Game Integrity

Assuming that you tried the two methods above but still experiencing some Kerbal Space Program 2 issues, you can try verifying the game integrity of Kerbal Space Program 2. Using this process, Steam will scan all the needed files or fix any corrupted files associated with Kerbal Space Program 2.

Kill Resource-Hogging Applications

Chances are you have lots of applications installed on your PC. Some of these applications have been constantly using the resources that possibly trigger Kerbal Space Program 2 crashing. We highly suggest closing the software that you are not using while playing Kerbal Space Program 2.

Some of the most popular software that eats lots of resources while in the background are Media Players, web browsers such as Firefox and Chrome,  and more. You can close these applications by closing them using the Task Manager.

Disable Antivirus

Another reason why Kerbal Space Program 2 keeps on crashing on PC is your antivirus. Antivirus companies have been usually updating their software to enhance security. There’s a chance that Kerbal Space Program 2’s executable file (.exe) is being marked as a virus. Disable or temporarily disable your antivirus or any security programs on your computer. If you download the Kerbal Space Program 2 from the official store, we’re 100% sure that the game files are safe. So, you have to exclude the .exe of Kerbal Space Program 2 and see if the problem has been solved.
