  • RAM Allocation: Kerbal Space Program 2, like its predecessor, is a heavy RAM consumer. So, close down every unnecessary program like Discord, Spotify, or other programs, and run Kerbal Space Program 2 alone. We recommend giving it at least 12GB of free RAM for a smooth performance.
  • Corrupt Files: Corrupt files are other culprits that can disrupt the performance of the game. You can repair the game files from the Steam Store by right-clicking on the game name and choosing the Properties option. Now, click on Local Files and select Verify Integrity of Game Files.

  • SSD Installation: Please install the game on an SSD for quick communication between your CPU and RAM. Avoid using any HDD and transfer the game to the SSD if you own one.

Remember, these are the early days of the game. So, you can always expect patches and updates to fix such annoying issues from the developers. Still, if your problem is too persistent, you can contact the Intercept Games Support page to lodge a personalized complaint.
