Hi Folks.
Just curious, has anyone tested TrueSpace on a Duel Core Processor system? When it comes to rendering, what (if any) are the speed improvements?
Paul. |

dual core athlon 4600+ is very quick. cant give specifics. i've mentioned in other threads that I have some problems, but I believe they're related to the nvidia graphics drivers, not the processor.
7.1 only appears to use one core unless rendering. |

first thing I noticed was there are two render lines moving down the screen at the same time [in lightworks], not just one..:D p4 3.0 g |

I think its time for another benchmark thread. I would love to see how the new dual cores are operating. I have a hyperthreading pentium and I get the two different rendering lines also.

Thanks. Any chance you can post a screen shot of the two render lines (if you can see them). I'd love to see what this looks like. |

The gap between the render lines can grow larger too - eg if one render light includes glass, and another doesn't, then the one with glass (particularly at an edge say) will take longer to render, while the other thread continues on rendering several lines.
Hyper Threading splits one processor into two in a "virtual" sense, while dual core is really two physically separate processors. Both the "virtual" and real processors can be allocated different threads. The benefit is more significant with two real separate processors (dual core).
HTH!

I wonder what would happen with more as 2 virtual or physical cpu?s
Does tS use these and assign to threads? Means 4 cpus would result in 4 render threads (or 4 render lines)? |

I've run tS on 8 physical CPUs and can confirm that with LightWorks set to multi-threading you do indeed see 8 render lines. |

I thought someone said tS wasn't supported on 2003? Or is it just that it'll work, but Caligari don't provide support for any problems that might occur whilst running it on 2003? :confused: |

It wasn't running on Windows Server 2003. You are right that tS is not supported on Windows Server 2003, though. |

Ok, now you've got me really curious. AFAIK, XP Pro can only handle 2 physical CPUs [number of sockets, not cores]. The only other version of Windows I know of that can handle more than 2 physical CPUs are some server variants of 2000. :confused: |

It was Windows 2000 with a customised HAL for the system. |
