Reality Factory

I HAVE SIS620 VIDEO CARD.WHEN I TRY TO OPEN REALITY FACTORY SCREEN GOES BLANK AND COMES OUT OF THE PROGRAM.PLEASE SUGGEST
A REMEDY FOR IT.I HAVE DIRECTX 9.C

THANK YOU.

I had an sis630 on my now-dead notebook, it ran reality factory, but
barely. You'll have to get a modern ATI or NVIDIA card to run RF.
