Apply the Shader in ReShade =========================== #. Launch your game with ReShade enabled. #. Open the ReShade overlay (usually by pressing the :kbd:`Home` key). #. Go to the :guilabel:`Home` tab. You should see :file:`MyGrayscale.fx` in the list of shaders. #. Check the box next to :guilabel:`MyGrayscaleEffect` to enable it. Your game screen should now appear in grayscale!
