Hi,
apparently there is some sort of a multithreading bug. If I set the process affinity of SupremacyClient.exe to all cores my CPU utilization is as follows: Attachment:

Hey Overlord, I didn't know you were affiliated with the Jad Engine--I've been following that project for a while. It's pretty cool. I've been thinking about using it for our combat engine.
This is certainly odd. I've got a multi-core machine, and I haven't noticed this before, but I'll do some testing. Thanks for the post! _________________ Lead Developer of Star Trek: Supremacy 253,658 lines of code and counting... |

Did I hear someone say combat engine?!?!
 It would be wonderful just to have a simple (rock paper scissors and no 3D combat view) temporary combat fix in the alpha. It would be wonderful to have more help with the 3D combat engine. Especially as I have spent the last two years collecting and building models for it.  _________________  |

Most of the CPU usage during regular gameplay is from the star and planet animations. Are you sure you had similar content on-screen when you did these tests?

I know you can get it done given time CDR.
It would be nice if you had some help. _________________ |

There might be some help on the way Wolfe - a new forum member, aeon, just posted. He says he has experience with Advanced 2D/3D Graphics Programming, XNA, DirectX, and WPF. Are those the sorts of areas you need help with?

Yes I was in the galaxy view, the CPU usage changed as soon as I changed the processor affinity (w/o doing anything else in the game). _________________ |

Could you please add an option or commandline switch that sets the processor affinity to the first core.
E.g. Code: Process.GetCurrentProcess().ProcessorAffinity = new IntPtr(1); _________________ |
