I opened the soft shadows of the sun, but do not see significant results?
The default diameter of the softshadows is 0.5 degrees with 9 samples.
The reason you can't see signifact results is either:
1) the softshadows diameter is too small. You could increase the diameter of the soft shadows and also increase the samples.
My sort of rule of thumb is:
0,5 degrees @ 9 samples
1 degrees @ 11 samples
2 degrees @ 13 samples
3 degrees @ 15 samples
This should give you clean soft shadows in the majority of cases.
Too low sample-amount gives noisy soft shadows.
2) The scales in your project are too large. 0.5 degrees is as in real life, so if you go for real-world scales and want to stick to 0.5 degrees soft shadows, then reduce the scales of your project (I mean powerfractal scales and displacements etc. etc.), but that's a real hassle often and getting the exact same result is impossible.
