I have done several tests in this regard. A lot of you are not going to be happy to hear this.
If you are using a computer that is running FPSC very satisfactorily, then any computer that has less performance may not run as expected or as you have tested it on your development system.
Whatever your system happens to be you should test your games on lesser systems to see how they will work. Only in this way will you be able to offer information to possible users as to the minimum requirements.
Unfortunately this is the nature of FPSC.
I am experiencing
excellent performance with my desktop development machine; and, it isn't even the top of the line. Bond1 recommended a better graphics card but I figured he needs a better one for making his models. He did say that the one I did get would be adequate, though, and it certainly is for me.
Here are my specs and system ratings:
==============================================================
processor - calculations per second 7.4
memory (RAM) - memory operations per second 7.4
Graphics - Desktop performance for Windows Aero 6.9
Gaming Graphics - 3D business and gaming graphics performance 6.9
7.9 is highest 1.0 is lowest possible

Although my system has a DirectX runtime version of 11.0 my video card only supports up to DirectX 10. That of course is a moot point since FPSC only runs DirectX 9.x
