Viewport AutoPause
An editor-only Unreal Engine 5.7+ plugin that automatically pauses viewport realtime rendering when the editor is idle or unfocused — cutting GPU power, electricity, fan noise, and heat. Resumes instantly on input or focus.
Features
- Idle pause — viewports stop drawing after a configurable idle timeout (3s by default)
- Focus pause — viewports stop the instant another OS app takes focus, and resume the instant Unreal regains it
- Active framerate cap — optionally limit the editor's frame rate while you work; can only ever lower it, never raise it
- Three pause modes — Standard, Aggressive, and Maximum — to dial in savings vs. convenience
- Pauses actively-playing Sequencer playback while idle, and resumes only what it paused
- Smart bypass — never pauses or caps the frame rate during Play in Editor (PIE) or Simulate (SIE)
- One-click toolbar toggle with a live green/red status dot; on/off state persists per-user across editor sessions
- Editor-only module — strips entirely from packaged game builds
