Meet the minimum requirements and updates

The game uses the Unity engine: If you do not meet the minimum requirements for Unity, you will not be able to play Gems of War on your PC. Find the minimum requirements here.

Close the game and properly exit Steam. Next, check the following programs are up to date on your computer:

  • DirectX
  • Graphics card drivers
    • For example, Nvidia released a new driver mid-2017
  • If you don't have Windows 8 or higher, download Windows 7
  • Update your operating system to Windows 10*

*We realise this is a drastic solution and understand if it isn't possible to try this.
