    @One Love
    Awesome find!
    I found many other instances of the Nvidia Threaded Optimization setting causing the same stuttering too, such as:

    @TNRFX
    regarding the specific combination it may be because people or reviewers were not aware of the issue and some might chalk it up to a TR regression rather than a Windows driver issue. I did find one other instance outside of Premiere, of this combo affecting games in the newer iteration of TR:

    https://www.hardocp.com/news/2018/08/15/amd_ryzen_threadripper_2990wx_gaming_benchmarks_stunted_by_faulty_nvidia_driver

    which references tests by German site golem.de where a 1080 Ti performs significantly worse in common games under 2990WX in Windows than RX Vega 64

    while there's a lot of discussion for these higher core parts around NUMA vs UMA and thread affiniity, from my reading that some scheduling issues/bugs in Windows still affects the lower core non-NUMA parts (1950x / 2950x) since there are two processor groups for windows to divide the threads into and two CCX in the hardware, where only one has i/o for the pcie slots.

    - which references this:
    https://bitsum.com/portfolio/coreprio/
    - and in there is this comment:
    http://disq.us/p/1ylr927

    "We run a game server (ARK) and noticed a similar issue that is fixed by doing the processor affinity in task manager. We have a TR 1950X. With our game server - ARK - what would happen prior to doing the affinity fix is that there would be periodic world freezes lasting about 200ms - long enough to cause lag. I think the problem that you fixed isn't just for high end 2990WX processors. It think that it is across any large NUMA node set processors such as TR."

    So I don't know if Game mode (limiting to 8 core / 16 thread) or setting affinity in Task manager after loading your project, during playback to specific cpu might yield some positive results, or using Bitsum's CorePrio tool

    (I'm relegating my 1950x for other tasks, for Windows, gtx1080 and Adobe CC I'm building a 9900k I just got over the holidy sale)

    @Alexander Mejia
    have you tried changing Project Settings > General > Renderer > Mercury Playback Engine Software Only

    Hi Andrew,

    your comments are as thoughtful as they are timely.
    While I usually would have to close this item as it isn’t specific enough, I’m gonna leave it open so others can see this and add comments:

    Please come back and vote for exactly the items that you feel need a V2, some polish, or just remove friction in areas that have grown over time. Add a new request if what you’d like to see revised isn’t discussed yet.

    We’re already seeing good patterns on User Voice as to which items and areas would be good candidates for upcoming releases. You can see some of the top runners already marked as “Under Review”. And while that won’t tell you with which release exactly we’ll have things ready for you, it’s an indicator of an investment we’re making to improve features and workflows where most users express their needs.

    Cheers,…

    Thanks for all the feedback. It’s pretty clear that we’ve got to look into the workflow using this format more closely, there are enough reports about gaps at this point to reopen this item. I’ll post more info about next steps shortly. In the meantime, a couple of questions are easy to answer:

    - The plugin is designed for Premiere Pro. It currently doesn’t provide support for After Effects.
    - It does work with AME, so if you want to use it for batch processing, that’s very doable
    - If you’ve started a project with Autokroma, there’s no easy way to transfer it to be running with the new plugin.

    Patrick
