GPU is not recognized and is mentionned as GDI Generic

This issue is a bit complicated to track and can be caused by multiple sources:

  • If you are on a computer with Nvidia Optimus, see the following link: GPU is not recognized
  • Check that your monitor is connected to your primary GPU (and that on Windows this monitor is set as your main display)
  • Check that the color bit depth of your main display is set to 32 bits on Windows
  • If you still have issues, try a clean reinstall of your GPU drivers (full uninstall with cleaning of the remains in the Windows registry).
