Other Methods


  • Driver Updates: Outdated drivers can be the problem. Visit the website of your graphics card manufacturer, such as Nvidia, and update the graphics driver. You can also update drivers from the Device Manager.
  • Disable Overlays: Overlays can be intrusive. Turn off in-game overlays in settings of platforms like Steam, Discord, and Nvidia. It can make a difference.

  • Turn Off Windows Game Mode: While it sounds good, game mode can sometimes have negative effects. Open Windows settings, go to "Gaming," and switch off the game mode.

  • Close Background Applications: Every bit of CPU power counts. Open Task Manager (Ctrl+Shift+Esc) and close unnecessary background applications that are not essential.

  • Clean Boot: This helps identify conflicts caused by other programs. Start the PC in a clean boot state, which disables third-party applications that might interfere with the game.

  • Check Graphics Application Settings: Ensure that your GPU settings are optimized for the game. Double-check the GPU settings in the control panel of your graphics card.
