Stars can be seen in the water.

@pedro16797 The game has been quite excellent, thank you for making such a good game. I can tolerate them. Jundroo's attitude in dealing with bugreports is very serious. Hope to see SR2 will be seen by more and more people.

What you are seeing there is the reflection of the sky in the water. It doesn't look great but with where the camera is positioned it's really hard to get realistic reflections without doing something like raytracing or other too performance intense techniques.

You may notice some issues with reflections near structures, reflections at some angles, reflections in the distance in small bodies like Nebra... Not much that we can do without major compromises and a lot of dev time

By the way,you can't see this if you are completely in the water.
