As the title! Please tell me if AOE3 uses hyperthreading and please tell me if it does, how to enable that feature? I have a Dual Xeon 1.8GHz system. The ctrl-alt-del shows that I have 4 cpus. I have enabled the hyper-threading in the Bios. I have Windows XP professional. The utility that came from Intel said I have only enabled the hyperthreading in the Bios but cannot detect it in the system. I have no idea why. Please suggest a way to tell if my system has hyper-threading capability or not under the windows XP environment. My system uses 860 chipsets.
