Scene Probe

The probe mode can be none, fps or metrics. To enable the probe, set the probe mode in the engine parameters. Then enable the probe in scenes where it is needed. An overlay must be active for the probe to work. The probe is automatically disabled when changing or closing overlays. The FPS will update once a second. To toggle metrics, press Ctrl+F12. Metrics are only updated when Ctrl+F12 is pressed, as extracting metrics data from the scene impacts performance.
