Short Description: When dual-core processors cause performance impacts

Who has a Dual-Core processor may can experience some performance leaks in games, although the hardware should be good enough.

In this case - if you have a AMD Athlon 64 X2 - you can download drivers from AMD which you can find here:
» AMD Athlon™ 64 X2 Dual Core Processor Driver for Windows XP and Windows Server 2003 Version (exe)

Additionally Microsoft has an inofficial hotfix for Windows XP (32-Bit), which may be included in the next service pack. You can also download it here, but you do all this on your own risk!
