Angus, the integrated graphics is not compatible with AFPD and AF5. You will need a good Nvidia or ATI 3D graphics card which is compatible with OpenGL version 2.0 and above. The recommended system and graphics card specs for AFPD can be found here

AF5 has higher requirements for the system and graphics card
