Ok, done and done.
What a thrill. Took 5 minutes to set and tune my controls. My graphics settings I never touched (Ultra IIRC), and enjoyed 40-60fps in space and on the ground. Should be good to go.
Simply beautiful work they've done with this. The sense of scale is dizzying. Landed just short of the junction of two huge craters on a moon at my home base. Dropped into the SRV, and realized that the crater rims were still more than 1km away! And the new surface music is wonderful. The ship exteriors are very detailed, and now the paint jobs are easy to see and worth having!
Bravo!
