Recently a range of dual-core CPU users - those who have Pentium D, AMD X2 and even Pentium 4 HyperThreading CPUs - are complaining of odd game problems, such as random crashes to desktop and lockups. It's happened due to motherboard developers incorrectly initialize processors. If any program use processor tick Counter, this program can FAIL on any dual-core CPU system. Windows constantly balances loading, and uses processors alternately. If both of the CPU have been initialized synchronously this problem does not appear. But most motherboards can not initialize CPU synchronously. If there is small time lag Between CPU initialisation, switching from one CPU to another will produce time shift, direct or Reverse. Time starts to flow jerky, that make work of most games unstable.
