sean24 (Sean is a great name, if I do say so myself), FWTOW is designed to run on gaming computers made in the last five years or so, though it should run on lower settings as far back as eight. We have never implied that this mod will run on PCs that could run FL back in 2003.
I have a decidedly average to low-spec gaming rig by today's standards and have no problems running the mod, if your pc is even vaguely recent it shouldn't have much of a problem at all... If it's not, then I apologise, but we have no intentions of lowering the minimum requirements.
