// foveated rendering for your desk

You only look at one screen.
Why power all of them?

eyedle watches where you look. That monitor runs at full power — the rest dim and throttle, and snap back the instant you glance over.

Is my camera recorded or uploaded?

No. Frames are processed in memory on your PC to estimate head direction, then discarded. No account, no cloud, no telemetry. Mouse-only mode never opens the camera at all.

Will it mess with the screen I'm using?

Your main monitor is never dimmed or throttled, apps playing audio are never touched, and anything you look at — or mouse over — restores instantly.

What if I don't have a camera?

Turn on Mouse-only mode in Settings — whichever monitor your mouse is on counts as the one you're watching, and everything else works exactly the same. No camera, no calibration. (It's also handy if you just don't want a webcam involved: in this mode the camera is never opened at all.)

Windows says "unrecognized app"?

Eyedle is new and unsigned, so SmartScreen is cautious. Click "More info" → "Run anyway".
