But it’s 9 years old. Please tell me there’s been improvement on this.
My slave machine is using so few CPU that I don’t even see the point of using it.
How can I change it ? I’d like to use it on the “Render current frame” button while I’m working on my scene, so command line rendering will not solve my problem.
