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! |

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? |

All that work for nothing, I know how your feel  .Regards Wolfe |

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? Aeon's Post. |

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); |
