Looking at computer games I thought. Way, this looks better than reality. Then I thought. Whats the difference between the photo realistic images and these computer rendered ones. Improving the image quality will only give game graphics that looks more than perfect. One idea is just to add a noise filter. Like Gaussian Filter found in GIMP. With this the reality port-aid in the computer image will look more forgiving. Looking more like the photo realistic photos we are used to. So my idea is to enhance the image with simple eye like limitations.
