So stupid question, with the 3950x being released in September, and the current 3900 available now, does the advice in this thread work well with those processors, or is it even needed? Looking to upgrade to one of them come black friday, and just curious!

Since I only have 1 16 core I'll try UMA next time with --pool 52 or something like that. |

Since at default frame-thread was 5 and I am currently setting it to 2 or 3 I am already improving quality - so with frame-thread 2 or 3 I doubt that anyone will see a difference. |

With x265 it's easy to saturate 8c 16t but it's hard to do 16c 32t at 100% - if u leave the defaults you are only utilizing 60 to 70% so about a 10c 20t CPU on UHD resolution. With tweaking u can get close to 100% but it's not yet clear if that degrades image quality or not - I can't see a difference but that doesn't mean there isn't any. |

Just activate Distributed Encoding in Ripbot264 and done
This way I can saturate hundreds of threads!

Splitting is done at keyframes reported by FFMS.

Hi, how can i do that in MeGUI? Currently I'm just using the option in the GUI menu to set the frame-threads to 1 to force it to just 1 thread because i don't know how to actually disable the frame threading altogether. All this while i only use GUI menu, not sure how to do it manually with MeGUI. Many thanks in advance.

Also, the potential quality regressions are proportional to the number of frame threads. I've found -F 2 as being generally safe while offering a big perf boost compared to -F 1 |

Before you start lowering the frame-threads parameter in all your encodes, I suggest you test how it looks. It's very likely that you won't be able to see the difference between -F 1 or -F 4.

True that. I've not really seen any substantial issues in a couple of years with higher frame threads. Doing more basic settings works reliably. When new features are introduced (RADL for example), there may be frame threading issues initially that get fixed later.

Sorry to dig up an old thread, but I've found the most straight forward way to utilise 12 core is to run two instances (and use 2 for frame threads). That results in constant 99.5%+ CPU utilisation. Without that, and with pmode, I'd only see ~65-70% utilisation.
