Why?! When I do heavy denoising stuffz, vspipe takes ca. 11-22% of the CPU. So, from that point of view, I can see why you would try and run multiple of those. The rest of the CPU is then usurped by the x264/x265 process.

So, what I don't understand then is how running two x265 processes concurrently lowers the amount of threads each uses. Or is that something you can actually set?

Thanks.
