In the next couple days I'll be installing it onto a quad core dedicated machine... I'll see how it goes on that system. |

I forgot to wire up that text to actually display the number of CPUs/cores. The bigger issue is why it detected 2 cores. I'm using Win32 apis getProcessAffinityMask, and it returns a bitmask where each bit represents a physical processor or core. Here's what it says: "A system affinity mask is a bit vector in which each bit represents the processors that are configured into a system." So for whatever reason, Windows thinks your CPU has more than one core. When you open the task manager performance tab, does it show two CPU usage columns, or just one? |

It says 2 threads, which means it is Hyperthreaded. The operating system reports this as two processors. |

 Never noticed that it shows two charts for CPU usage... I usually only look at the apps and process tabs... but I know this is a single core processor: http://ark.intel.com/products/36331 Windows bug?? |

No, Micro figured it out. I just need to make my setting more clear as to what it's actually doing. Set it to dual and you'll get the most out of your system. |

Not a windows bug, as much as it is just a lack of information. A Hyperthreaded processor has two logical processing threads. Dual hyperthreaded quad core processors will show up as 16 processors in windows. Windows displays a processing thread as a processor regardless of weather it is a Hyperthread, Multi-core, or physical processor. If this is being handled at the hardware layer, windows may not even be aware of the difference. Mayby a future version of windows will report actual processors, cores, and threads. |

I know TWGS isn't aware of a difference ;) I'm going to change this to a simple checkbox that says "Limit processor count", which is grayed and unchecked for 2 or fewer processors detected, but enabled and unchecked by default for 3+ processors detected. Then it isn't confusing if it thinks you have more processors than you have. |
