Do you show 70% on both cpus if you use a load tool, like top? As Hannes explained to me recently, the "Use only one CPU" option means really to use a single worker thread to dispatch frame rendering jobs. They still get shared on multiple cpus. > > It even takes the same time to Render if i use one or two CPU´s. Not > sure why. > What do you mean by 'use one or two cpus'? I can disable a core in the bios on an AMD X2 and have rendering take about twice as long. > The only thing that helps here speed up things is the Renderfarm (using > 3 boxes). If cinelerra is really only using one of your CPUs, you can run a renderfarm node on the same machine. But that should not be necessary.
