# ComputeGraphSimulation.SimulationRate.Mode.fixedTime

Simulate using time delta.

## Declaration

```swift
case fixedTime
```

## Discussion

Discussion Similar to fixedFrequency except the timeDelta is in seconds. This can result in zero, one, or more steps per frame, depending on the frequency specified and the current framerate.
