Some graphics cards do not support multisampling with DirectX-enabled 3D graphs. Multisampling is used for anti-aliasing, making the edges of the 3D objects in your graphs appear less jagged. If a DirectX 3D graph does not display correctly on a runtime computer, you can turn off multisampling by creating a PB_Graph_Multisampling system environment variable and setting it to FALSE. If this does not work, you need to replace the graphics card to display DirectX 3D graphs correctly. [CR 530128]
