Two prosessors

[Anonymous]

We have an PC running windows XP. It runs a Xeon 3.2 prosessor and 3 gb of ram. Now we want it to render faster, and I'm thinking of upgrading with one more prosessor.

We are converting to MacPro now, but this machine is just a few month old, and I want it to be faster.

Do anyone have any experience with the effect of two prosessors?

Archicad is not multi-threaded, so multiple processors have little effect on its performance.

Tom I thought that the Lightworks rendering section is supposed to take advantage of 2 processors. I know that AC can't but is this not correct about rendering?

Cheers,

Lightworks does, kind of.

The Lightworks application which does all the actual rendering does use multiple processors. The Archicad end, rebuilding the model and translating it into Lightworks' format does not.

Basically, a 4-processor machine will still take longer than 1/4 of the time that a single processor machine would because it's not the entire rendering process that's multi-threaded.

I understand that it doesen't go twice the speed, but will it be any faster?

Lightworks Rendering will run faster on multiple processors. Nothing else will.

The only other thing you could do to improve the speed would be a faster processor.

Thank you. Or change all machines to macpro, it renders the same file 4 times as fast.
