OrbitOverlay 1.9.1

Overlays update at your headset's refresh rate, not the game's

• OrbitOverlay used to update once per game frame. Measured with VRChat on a 90 Hz headset, that was 63-83 times a
  second, while SteamVR presented 75-85 frames. Whenever the game dropped a frame, the overlays skipped it too: the
  cursor, a panel you were dragging, mirrored video and the watch's animations.
• It now runs on its own high-resolution clock at the headset's refresh rate (measured: 90 ticks/s, 0.23 ms spread).
  Every frame SteamVR shows, reprojected ones included, gets a fresh overlay, and an update waits about half a frame
  on average before it is shown, instead of a whole one.
• It no longer pauses for ~35 ms when SteamVR doesn't signal a frame in time.
• With the headset off it ticks slowly, so it doesn't spin for nothing.
• The log's perf line now also shows the game's and the compositor's frame rates. Setting HeadsetPacing: false in
  config.json brings back the old pacing.
