## SolverDeactivation

A list of possible solver deactivation settings. This value defines how the
solver deactivates objects. The solver works on a per object basis.
Note: Solver deactivation does not save CPU, but reduces creeping of
movable objects in a pile quite dramatically.

### Choices

Number | Name | Description
--- | --- | ---
0 | SOLVER_DEACTIVATION_INVALID | Invalid
1 | SOLVER_DEACTIVATION_OFF | No solver deactivation
2 | SOLVER_DEACTIVATION_LOW | Very conservative deactivation, typically no visible artifacts.
3 | SOLVER_DEACTIVATION_MEDIUM | Normal deactivation, no serious visible artifacts in most cases
4 | SOLVER_DEACTIVATION_HIGH | Fast deactivation, visible artifacts
5 | SOLVER_DEACTIVATION_MAX | Very fast deactivation, visible artifacts
