It was discussed in a technical interview: it was implemented, evaluated, and rejected, for requiring too much performance for little visual advantage. It's an expensive feature, and comparing a game with a much smaller world doesn't do justice to the performance impact.
Thank you for the quick response!
But isn´t full tessellation more expensive than dynamic tessellation?
Please tell us how to change tessellation level in the game (ini files user settings etc.) We saw that on AMD cards putting the tessellation on 16x they get a lot more performance. Save our day!
