# SIMCONNECT_RECV_EVENT_FRAME<no value>
The **SIMCONNECT\_RECV\_EVENT\_FRAME** structure is used with the [SimConnect\_SubscribeToSystemEvent](../general/simconnect-subscribetosystemevent/) call to return the frame rate and simulation speed to the client.

 

##### Syntax

``` cpp
struct SIMCONNECT_RECV_EVENT_FRAME : SIMCONNECT_RECV_EVENT {
        float  fFrameRate;
        float  fSimSpeed;
      };
```

| `fFrameRate` | The visual frame rate in frames per second.                                                                                |
| `fSimSpeed`  | The simulation rate. For example if the simulation is running at four times normal speed - 4X - then 4.0 will be returned. |

##### Remarks

 

This structure inherits the `SIMCONNECT_RECV_EVENT` structure, which inherits the [`SIMCONNECT_RECV`](simconnect-recv/) structure, and is returned when the `dwID` parameter of [`SIMCONNECT_RECV`](simconnect-recv/) is set to [`SIMCONNECT_RECV_ID_EVENT_FRAME`](simconnect-recv-id/). Set the requested system event to "Frame" or "PauseFrame" with the [SimConnect\_SubscribeToSystemEvent](../general/simconnect-subscribetosystemevent/) function to receive this data.
