hi, i'm using windows xp pro and an athlon xp 2500+ processor. also i have another portable computer which is an intel pentium IV 1800 and have xp pro installed on it. In both computers cpu usage is always above 90% while playing the game. I don't think that civ2.exe needs that much of cpu usage. As a result my athlon 2500 computer always gives warnings about temperature problems. So i checked the temperature of the CPU and it showed 60 degrees celcius!!! Is there any patch for this problem or civ2.exe really needs that much of cpu??
