CabMasterPro User Guide
See System Requirements - CabMaster Software 
. The hardware specifications listed here should be considered the minimum required for reasonable performance. Most recent computers will meet or exceed these requirements, but you would be advised to check before purchasing a new machine.
Normally for a new computer we would suggest looking at a "Gaming computer" as this will point you to the scale of computers that have components of a higher quality than normal i.e. Fast CPU, More RAM, high end Graphics card.
Mac Computers
CabMaster runs on the Windows Operating system, however it can be used on an Apple Mac computer where a windows environment (such as "Bootcamp") has been installed. CabMaster Software does not provide technical support of Bootcamp or other emulators, only AllMasterSoftware products.
Since standard systems these days come with hardware that far exceeds these minimums, the most cause of this problem may be that the video card in your system does not have any 3D acceleration features. Most people tend to overlook the quality of a video card when buying a new computer and therefore sellers may include the cheapest one available. For any machine that will be used to run CabMasterPro, you should make sure that you are getting a good quality 3D accelerator .
If you are thinking about buying a graphics accelerator for an existing machine, you should check the FAQ on 3D Accelerators for a list of some of the top 3D cards on the market. It may be a more effective upgrade than you think - today's 3D cards have good performance for very low cost.
