When you install Evoke, a Vicon Evoke desktop shortcut appears on your desktop (and an entry is added to the Windows Start menu).

(Depending on the options selected during installation, you may also see icons for Vicon Retarget, which lets you create retarget setup files (*.vsr), used by Evoke for retargeting; the Vicon Firmware Manager; and Vicon Video Viewer.)

- Double-click the Vicon Evoke icon to start Evoke, and ensure the **System**  panel is visible.
  From this panel, you monitor and control devices connected to the software.

### Windows power options monitoring

When you first start Evoke, you may see a warning icon on the right side of the menu bar, like this:

This icon indicates that the current power plan is set to favor power savings over performance. The power-saving features of Windows can significantly reduce Evoke's performance and increase output latency, depending on the power plan that is chosen and the processor support for power-saving features.

For more information and access to the **Power Options** in the Windows Control Panel, click the icon.

For best performance in VR, choose the **High performance** plan (or a plan created from the High Performance plan).

## Ensure optimal latency

To ensure optimal latency for all scenarios, be sure to use Low Jitter Mode:

1. Display the **Processing** panel (**View** menu > **Processing**).
2. In the **Object Tracking** section, ensure **Low Jitter Mode** is selected.

> ⚠️ **Caution**   
> ⚠️ Using cameras with a resolution above 5 megapixels may result in sub-optimal latency performance. When using a virtual reality headset, this is not recommended.
