Unity - On-Demand Rendering

On-demand rendering is a rendering technique that reduces power consumption by only rendering when necessary.

Benefits:

• Reduced power consumption
• Improved battery life on mobile devices
• Reduced heat generation

To enable on-demand rendering in Unity:

QualitySettings.vSyncCount = 0;
Application.targetFrameRate = 0;

Then use:

Screen.sleepTimeout = SleepTimeout.NeverSleep;

Or implement a custom update mechanism:

void Update() {
if (inputDetected || animationRunning) {
RequestRedraw();
}
}

This allows the game to render only when user input is detected or an animation is running.
