My game runs better with the shader quality set to high instead of low or medium. I have a video card in my computer, and it seems to use more GPU and less CPU the more I turn the shader quality up. This is according to the basic windows performance monitor; I didn't look in my NZXT Cam but is that what the game means when on the shader quality setting it says low is for low performance machines? Is low performance = no video card i.e., use more CPU? When I put it on low my game just goes much, much slower. The only reason I could think was that it wasn't using the GPU as much, and when I looked, sure enough, my GPU was being used much less.
