Rift 1.9.7

A performance-focused release.

Performance

Dramatically lower GPU and CPU usage. Rift now throttles its render rate when the window isn't focused or minimized and freezes idle animations, so background graphics use drops to near-zero (roughly 0.2% GPU idle, and about 2% during a call on a laptop GPU). Cooler, quieter, and much easier on battery.
Starts with no internet. Launch Rift offline and you get a clean local "No internet" screen (logo + a rotating "Did you know?" tip) that keeps pinging and loads straight into the app the moment you're back online - instead of a blank window or a browser error page.

Screen-share controls. Toggle your stream's audio on and off live without restarting the share, and pick your resolution and frame rate (up to 60 FPS).
Server Stats location now has an IP-geolocation fallback so it still resolves when precise location isn't available.

Voice call join loop. A friend on a slightly older build could get stuck joining and leaving a call over and over (which also caused reconnects for everyone else). Clients now update once and join, instead of bouncing.
Two Rift icons in the system tray after an in-app update - the old icon no longer lingers.
Light mode: the voice call area and game-activity backgrounds render correctly now (no more black panel).
Fixed a blank call view when spotlighting an activity, then another user, then the activity again.
Mute / deafen no longer flash the whole call view.
Custom-background videos no longer spin up extra background processing.
Your @username is now hidden in the profile popout and settings while streaming (it's what people use to friend you).

Completely redesigned mobile UI (iOS / Android / mobile web): a real bottom tab bar - Home (DMs + Friends), Servers, Notifications, Profile - with mobile-native screens, instead of the desktop layout crammed onto a phone. Settings, server discovery, and channels are all built for touch now.
