Turning the picture off did not make Farcamp's frame time disappear. That made it a useful question: what work was the game still doing when there seemed to be nothing left to draw?

A console command, **debug**, now opens reversible controls for rendering, the interface, presentation scripts and the simulation. The panel gives a running game a set of switches, more like an electrical breaker board than a single “make it faster” button.

Each switch helps narrow the question:

```mermaid
flowchart TD
    A["Watch frame timings"] --> B["Disable one layer"]
    B --> C["Compare what remains"]
    C --> D["Restore and check behaviour"]
```

The resulting pass cut repeated work in several places. Colonist updates send changed fields instead of everything every frame. Unchanged appearance and interface work can sleep. Hidden world creatures avoid needless presentation updates. Fire shadows do less work in daylight, and the physics engine sleeps while no body needs to settle.

Sleeping has to come with a reliable alarm clock. Review caught cases where hidden colonists still needed rig upkeep and a falling body needed its callback restored. Those were corrected before the owner-approved merge. Each optimisation is documented separately so an unwanted visual change can be undone without throwing away the whole pass.

There is no single clean before-and-after frame-rate number attached to this entry. Switching layers off is a diagnostic aid, not proof that the remaining milliseconds have all been explained.

The same debugging workflow now prefers inspecting a reported live reproduction first and can gather that state in one call. Inspection-only game instances are closed when the work is finished.

## Open questions

- Representative frame and tick measurements are still needed for a defensible overall gain.
- Disabling presentation scripts also pauses the inspection bridge; hiding the interface hides the console.
