If you are concerned about how your computer is coping with the demands of displaying 2D and 3D garments, you can use the Statistics feature. This feature, if enabled, displays the frames per second (FPS) at which the computer is operating at the top right of both the 2D and 3D windows.
To enable Statistics:
On the Main Menu, click View.
Then, click Show Statistics. The FPS is displayed in the windows.
To disable, repeat steps 1 and 2.
