If the status bar is enabled (see Options for how to switch on and off the status bar) and a device has been initialized and is currently transferring data various data is displayed here:

ImpactControlCenter - Status Bar

From left to right the following data is available:

FPS: The current frame rate as a slow running average. The value will slowly adjust to the current capture frame rate and will be reset to 0 if the acquisition is stopped or the internal acquisition engine runs out of buffers to capture data into
Display Frame Rate: The current rate captured data is displayed with. This value will never be higher than the FPS value. Capturing data has the highest priority and display updates will be skipped in favor of being able to capture and process all data. The rough display frame rate can be configured via 'Settings → Set Update Frequency...'
MB/s: The current average bandwidth used for capturing data from the selected device
Frame Buffer Usage: The current fill level of the device's frame buffer. This is a feature only available for certain Balluff devices. A value somewhere around 0 which sometimes increases and sometimes decreases would be normal. An ever increasing value or a more or less constant value of 100% indicates a bandwidth problem
Frames: The value of the 'FrameCount' property from the 'Statistics' property list. In contrast to the 'FrameNr' property display in the image overlay this value is even increased for timed out, aborted or otherwise erroneous buffers. See tool-tip/documentation of that property to find out more
Errors: The value of the 'ErrorCount' property from the 'Statistics' property list. See tool-tip/documentation of that property to find out more
Timeouts: The value of the 'TimedOutRequests' property from the 'Statistics' property list. See tool-tip/documentation of that property to find out more
Aborted: The value of the 'AbortedRequestsCount' property from the 'Statistics' property list. See tool-tip/documentation of that property to find out more
Lost: The value of the 'LostImagesCount' property from the 'Statistics' property list. See tool-tip/documentation of that property to find out more
Incomplete: The value of the 'FramesIncompleteCount' property from the 'Statistics' property list. See tool-tip/documentation of that property to find out more
Image: The dimensions and pixel format of the buffer currently displayed
(x,y): The value of the pixel of the current coordinates when moving over the image with the mouse pointer
