Use the Graphics Memory Usage view to display the private, +shared, or total graphics memory usage of processes running on a device. The +graph portion of the Graphics Memory Usage view shows the amount of graphics +memory used by the processes, and, if selected, the total amount of graphics +memory used at the time intervals selected for the GPU sampler in PI Profiler. +A list of processes appears at the bottom of the view showing the private, +shared and total memory usage for each process.
+ +Data in the Graphics Memory Usage view is layered with the shared memory +usage data overlaying the private memory usage data. Private memory usage is +represented by light blue color, while shared memory usage is represented by +light green. You can select to view either private or shared graphics memory +usage, or both of them combined, by using the view options available in the +Title bar drop-down menu, shown in Figure 1, or in the +Investigator > Graphics Memory Graph Menu .

+ +According to the selection, the graph displays the following (Figure 2):
+Additionally, a black line indicating the total graphics memory usage is +available. The line is always displayed by default, but you can choose to hide +or show the line by either right-clicking on the graph and selecting +Show Total Graphics Memory Usage, or by selecting +Investigator -> Graphics Memory Graph +-> Show Total Graphics Memory Usage.
+ +NOTE The difference between the cumulative (combined shared and +private usage) and total memory consumption (provided by the internal API) is +explained by the graphic acceleration system component itself: it cannot be +tracked by the GPU sampler of PI Profiler and therefore it is not visible in +the cumulative graph. In addition, if some graphics memory has been reserved +bypassing the graphic accelerator, for example using ARM interfaces (e.g. +camera application), the difference is even bigger.
+ +You can also move the mouse pointer on top of the graph to see the amount of +graphics memory used at that time as a tooltip, as shown in Figure 2 below.

+Columns may be reordered, resized, and sorted by clicking or dragging column +headers.
+ +Information on the graphics memory usage is also available in a separate Graphics Memory Usage +Statistics dialog. You can open the dialog from the context menu by right-clicking on the Graphics +Memory Usage graph and selecting Graphics Memory Usage +Statistics; or by selecting Investigator -> +Graphics Memory Graph -> Graphics Memory +Usage Statistics.
