pouf pouf , i’m working on a Ahtlon 64 DualCore 3800+ on XP home . here is my problem : when i open blender , in the affinity of the “processus” ( ctrl+alt+supr > right click on blender > affinity ) only one core (the second) is marked. so i mark the first one :http://mcnaze.free.fr/nimp/Processeur.png

I ‘say to blender’ that he must use 2 thread ( F10 ) and i render a scene , during this rendering i look in the Software Everest and see that only one core is working ( the second):

what can i do to use the two core ?

have you tried using more than one thread? Output panel, Threads field.

I was wondering if your other software is able to multi-thread? Sounds like you’ve turned on multi-threads in the render options so you would think that would be it. I don’t have an AMD so no real help here.

maybe you just need to coax it a little, like sing to it, or tell it a story…you know, give it Happy Thoughts.
