Listen while you glide. The wind past your ears rises and brightens as you speed up, and it is louder than it was. Fly slow, or let the wing go light, and the hide sail flutters and luffs, then goes quiet once it loads up. Meeting the edge of a thermal gives a soft swish of air, and on a real pull the frame gives a low wood-and-rawhide creak, at most every 7 s.
Speed shows as well. The view widens by up to 8 degrees as you near top speed with Shift+W. The fast shiver that came with it is a slow, small sway since November 4, and the view no longer twitches on bumps in the air. Reduce camera motion, under Controls in Settings, turns these view effects off.
A beeping variometer, which sounded when you were climbing, went in on October 29 and came out the same day in favor of the sounds of the wing itself, and no whistle tone was added. The sail sounds are generated, and they and the creak were picked by measurement, not yet by ear.
