I then decided to play for a little Volta 2 (fantastic mission btw), just to test the visual changes and the first thing i noticed, was that the water behaved bad, don't know if is a already known problem but the way i can describe it, is that everything below the water line was moving side to side in a constant motion, like a pendulum, the water "warp" effect was also not working correctly. The soft stencil shadows looked fantastic and i didn't saw any serious problems with them, at least in the little i played. Water bug aside 2.06 looks very promising to me.
I'm playing on a AMD R9 270X with the latest Adrenalin drivers.
