With newer viewers and better settings you get a nicer world. But..... Many light sources are set wrong.
Small example how bad ligts look inworld. And yes this is how the places look for me.
Problem, the light source is set to high with newer videocards and settings the lightsource can be down with at least 0.5.
Also to many light sources close togehter require a lower setting. You can check it yourself by enable the deffered lightning or light and shadow in the preferences. The good thing from that setting is that you can finaly have more nice lightning in places and see more then 6 light sources. you only need adjust things better.
