yet another screen-space ambient occlusion shader.
original technique is HERE by Arkano22.
I tuned it up a bit adding my circular texture sampling and pattern sample filtering.
Right now it is the best depth-only based SSAO I have come across.
another screenshot with noise dithering and "garea = 0.4;" instead of "garea = 0.6;" to lighten scene a bit.
scene with and without ssao:
