Ok, two things happened:
1.) After finishing the base code for my new testscene I encountered that I have a too low fog resolution. But:
2.) JCL adds a NOFOG flag for views. As soon as the new beta is out I will adopt to this, and
3.) I realized that I --HAVE TO-- improve the visual quality of the SSAO because on very clean scenes with lots of rounded, planar surfaces ... it sucks like hell - in terms of AO bleeding!

So here is what I will do the next days:
a.) polish the changed code
b.) make a release

The fog support is currently done in the shader and as soon as I get the new beta I will switch the fog code. Then I focus on the AO bleeding and stuff...
