Sure, what are you trying to optimize for:8Ringer wrote: ↑Mon Jun 29, 2020 8:35 pmis is possible to get that perforamnce bump with a single encode? Or is x265 encoding really just limited to not fully using all 24 threads? And before you snipe back (as I know you're going to do), the fact that there is 12% more performance left on the table with 2 encodes proves that the CPU isn't out of execution resources as you glibly stated above, mduell. Are there tweaks that can be done os is this the best I can hope for? If thats it, then thats fine, just curious if I can optimize my workflow and wring all the things out of these CPUs. While 12% is nothing in the scheme of things, if its on the table I'd like to leverage it if I can.
FPS? Pick a faster preset.
CPU usage? Try both slower and faster presets to see where it ends up. Try removing the advanced options you've picked, or picking a different aq-mode.
Seeing a significant benefit from x265 over x264? Upgrade to 4K content.
If the CPU doesn't have the right execution resources available at the right time, your encode isn't going any faster. Doing 2 encodes at the same time is going to shift those demands, since now you've got another decode thread running.
