FPSCX10 can only run on Direct X 10.0 or 10.1 supported video cards made by either Nvidia Or ATi with the Nvidia Gefocre 8xxx series or higher or ATi Raedon HD 2xxx series. While some Intel chips does support Direct X 10.0 or 10.1. There has been no reports (none that I could find) of these working with FPSCX10.
Also FPSCX9 Isn't offically supported under windows vista or windows 7. As the program was designed and released For Windows XP. However, With UAC (User Account Control) Turned Off. And updating FPSCx9 to the lastest version (V1.17.005 BETA or 1.16.018 Offical) should help with some compatibility issues you may or may not encounter. There has be numerous users that have reported no issues under windows vista and windows 7 after the 1.16 update was released.
FPSCX10 also isn't offically supported under Windows 7. As the program was designed and released For Windows Vista. Direct X11 seems to also give FPSCX10 problems as well.
