As specified on this site:
That video controller supports software based vertex shader, which means that this is supported through the driver and running through the processor on the system.
Some video games or applications require hardware based processing which implies that this is done by the video controller.
In this case you should confirm this with the video game developer and check if in fact this would be enough to be able to support the game on your system.
