What causes severe frame rate drops and system lag in Rainbow Six Siege?

I have been experiencing a problem with Rainbow Six Siege where the game randomly starts to lag when I fire my weapon. The game registers my input and sound correctly, but the screen becomes very choppy and almost freezes. The lag also affects my whole system and makes it difficult to switch to other applications. This issue only occurs in Rainbow Six Siege and not in other games. How can I fix this problem?


Rainbow Six Siege is a popular tactical shooter game that requires fast reflexes and smooth gameplay. However, some players may encounter a frustrating issue where the game starts to lag severely when they fire their weapon. The lag not only affects the game performance, but also the whole system, making it hard to switch to other applications or exit the game. This issue seems to be specific to Rainbow Six Siege and does not occur in other games. What causes this problem and how can it be fixed?

The possible causes of the lag

There are several possible factors that could cause the lag in Rainbow Six Siege. Some of them are:

  • Hardware issues: Your computer may not meet the minimum or recommended system requirements for the game, or your hardware components may be overheating, malfunctioning, or outdated. This could result in poor performance and stability issues in the game.
  • Software issues: Your game files may be corrupted, missing, or outdated, or your game settings may be incompatible with your system. This could cause errors and glitches in the game that affect the frame rate and responsiveness.
  • Network issues: Your internet connection may be unstable, slow, or congested, or your firewall or antivirus may be interfering with the game. This could cause high ping, packet loss, or disconnections in the game that affect the gameplay and synchronization.
  • Driver issues: Your graphics card driver may be outdated, corrupted, or incompatible with the game. This could cause graphical errors and performance issues in the game that affect the frame rate and quality.
  • The possible solutions for the lag

    Depending on the cause of the lag, there are different solutions that you can try to fix the problem. Some of them are:

  • Update your hardware: If your computer does not meet the minimum or recommended system requirements for the game, you may need to upgrade your hardware components, such as your CPU, GPU, RAM, or SSD. This could improve your system performance and compatibility with the game. You should also check your hardware temperature and fan speed, and make sure they are not overheating or malfunctioning. You can use a software tool like HWMonitor or SpeedFan to monitor your hardware status.
  • Verify your game files: If your game files are corrupted, missing, or outdated, you may need to verify the integrity of your game files through Steam or Uplay. This could fix any errors or glitches in the game that affect the frame rate and responsiveness. To verify your game files, follow these steps:
  • Launch Steam or Uplay and go to your game library.
  • Right-click on Rainbow Six Siege and select Properties (Steam) or Verify files (Uplay).
  • Click on the Local files tab (Steam) or the Verify files button (Uplay).
  • Wait for the verification process to complete and then launch the game.
  • Optimize your game settings: If your game settings are incompatible with your system, you may need to optimize your game settings to match your system capabilities. This could improve your game performance and stability. To optimize your game settings, follow these steps:
  • Launch Rainbow Six Siege and go to the Options menu.
  • Click on the Display tab and set the Display mode to Fullscreen, the VSync to Off, and the Resolution to match your monitor’s native resolution.
  • Click on the Graphics tab and set the Overall quality to Low, Medium, High, or Custom, depending on your system performance. You can also adjust the individual graphics settings, such as Texture quality, Shadow quality, Anti-aliasing, etc., to suit your preference and system performance.
  • Click on the Apply button and then exit the game.
  • Improve your network connection: If your internet connection is unstable, slow, or congested, you may need to improve your network connection to reduce the lag in the game. This could improve your gameplay and synchronization. To improve your network connection, follow these steps:
  • Use a wired connection instead of a wireless connection, as this could provide a more stable and faster connection.
  • Close any background applications or programs that may be using your bandwidth, such as web browsers, streaming services, downloads, etc.
  • Restart your router or modem, or contact your internet service provider if the problem persists.
  • Disable or configure your firewall or antivirus to allow the game to run smoothly. You can check the official Ubisoft support page for the list of ports that need to be opened for the game.
  • Update your driver: If your graphics card driver is outdated, corrupted, or incompatible with the game, you may need to update your driver to the latest version. This could fix any graphical errors and performance issues in the game that affect the frame rate and quality. To update your driver, follow these steps:
  • Go to the website of your graphics card manufacturer, such as NVIDIA, AMD, or Intel, and download the latest driver for your model and operating system.
  • Run the installer and follow the instructions to complete the installation.
  • Restart your computer and launch the game.
