Why is my Rainbow Six Siege crashing?

Rainbow Six Siege keeps crashing due to poor hardware specifications of your PC, resource-consuming apps that create overlays on your screen, the fact that OS and the game are installed on different partitions, corrupted game files, an outdated GPU driver, problems with the Windows Firewall, or pilled-up cache files.

How to fix Rainbow Six Siege crashing?

First, perform some initial checks and quick fixes:

  • Check the system requirements: If you want to play R6S without interruptions and with a decent FPS, your PC must meet at least the minimum requirements for Rainbow Six Siege.

  • Check the system and game locations: Some players report that having the operating system on one partition and the game on another caused frequent crashes. Check if this is the case for you.

  • 💻 Disable fullscreen optimizations: Fullscreen optimizations boost performance and prevent crashes. However, many players noticed that disabling them stopped R6S from crashing.
