Extremely slow playback after update

Hi, I updated to 26.5.2 yesterday and since then playback is extremely slow, only appears to be showing a single frame every half second or so. Outputting media is also extremely slow - a project which only took about 2 minutes to output yesterday morning is now taking well over 30. 

I’ve tried most of the obvious stuff like rebooting, clearing the cache, making sure hardware encoding is enabled and I’ve updated my graphics drivers to no effect. Everything was working absolutely fine before this latest update.

    Hello ​@Take One 

    Welcome to the Premiere Forums! Thank you for posting. We will need a little more information to help us identify the issue. 

    • Operating System: Specify Windows version.
    • GPU and Driver (Windows only): Please let us know your video card and driver version. We recommend updating to the most recent version; for NVIDIA users, we strongly recommend the Studio version of the driver.
    • Video Format: If the issue relates to playback or export, please specify the format (and ideally share a sample video).
    • Project Size: About how big is your project file? Is it in a Production? Approximately how many clips are involved in a rough estimate?

    I can provide you with a private upload link if you’re able to share a sample file. 

     

    Helpful Context

    Comparing when and where the issue occurs helps us narrow down the cause:

    • Does it affect all projects or only some?
    • Does it affect new projects with the same media freshly imported and placed on a sequence?
    • Can you import the old sequence into a new project and playback?

    Hoping to help,

    Amy

    Hi Amy, here’s the information you requested: 
    OS: Windows 11 Pro 26H2

    GPU and Driver: Nvidia Quadro RTX 4000, 597.30

    Video Format: MXF - It seems to playback okay if the source files are MP4s though, so maybe it’s a codec thing?

    Project Size: 74kb (this is an extremely small and simple project with only about a dozen clips involved, but it appears to be affecting every project on the machine)

     

    Additional context:

    This appears to be affecting every project, and happens even on new projects with freshly imported media. Importing the old sequence into a new project results in the same playback issues. 

     

    If I can’t get this fixed today then I’ll have to roll back to a previous version of Premiere as I have several clients who are currently waiting for their projects to be completed, so any help to get this resolved would be gratefully appreciated! 😅

    I’ve now rolled back to 26.0.0 so I can keep working for now and it looks like that version is still working okay. Still looking for a more permanent fix though. :)
