You are right about that, but once I decreased AO amount a bit compared to my 0.119 amounts, it was OK.
I focused on geometry first, exactly what you are talking about.
I don't know if grass can be solved, but I think we will always have downsides....
What I think is, overall, I really prefer 0.120 because its increase in quality makes me forget that grass thing...
Sure that some things will depend on game's normal maps, and apparently Bethesda made same mistakes as always with it (inverted channels, etc...)
Good luck Boris ! What I say is that if there are more improvements than downsides, it's OK
