To ensure that your PC launches the game with a graphics card and not an integrated card, follow these steps:
Windows 10 and 11
Settings > systems, screen > graphics:
If the game is not in the list browse and add the game (select the game's .exe file in the installation folder).
Once in the list select the game then options and finally select the Nvidia or Radeon graphics card to use, validate and try to restart the game.
