Ok so after that depressing news....this is the description of my CPU, probably still under spec but a bit clearer the my ealier information:
AMD Athlon X2 64 2.5 GHz,
Oh, that processor again is above the minimum specs .
also I cannot find the graphics cards listed in the specs. so what can I use if I do not find those.
You might want to take a look at this chart and see if you can find a comparable card or above them.
That will not be totally accurate, but mostly enough.
For a really accurate help you'll have to wait for one of our hardware pros here.
Also why am I sudden;y having problems with my other civ games that were working fine before and are not on Steam?
Is it a problem? Sure, the processor might be at 100%, but maybe the games are also running faster. Do they?
