Horizons, with this new ED season have a lot changed for me. As first ... there are many new places for visit (with countless very nice sceneries), very entertaining flights in low altitude, possibility to leave ship and use SRV (vehicle), and also new mission types and theirs combinations between space and the planets surfaces ... all this multiply possibilities how to have fun. You can spent few hours in Combat zone (CZ), hunt bounties or trade/smuggle and want/need relax, then visit some airless planet/moon and fly at high speed only a few meters above surface in deep canyon, or you can visit some from fortified settlements and tease their air defence, or you can support yours mate which is in his SRV on the surface after he in a hurry leaving guarded settlement after successful infiltration.
Horizons came not only with new in-game stuff, but there was also global system change from 32 to 64bit. I need to say that for me is ED on 64bit working much smoother as it was before, fps
