laggy playback in premiere

I routinely have super laggy playback where I drop tons of frames and I can't seem to find the issue. 

GPU: gtx 1080ti

CPU intel i7 9700f

RAM: 32 GB

using an external SSD for footage along with internal SSD for Premiere.

I have tried just about everything, I updated my STUDIO driver with nvidia, cleared the cache, using proxies, I have 29GB of RAM reserved just for Premiere, not using maximum render quality, lowered the playback quality in the playback window, using GPU acceleration(although the option is greyed out for some reason so I can't switch back to just GPU for rendering anyways), my GPU and CPU aren't on high usage whenever I edit, obviously restarted my PC and Premiere, I have also tried different footage in a completely new project with nothing in it besides 15 seconds of footage and audio, and I'm running premiere 24.0. I seriously can't find the issue, plus this is the thing. this doesn't happen all the time, only sporadically.

@soren5FE2 

Where are your video files being stored and how confident are you that the storage media can sustain the data transfer rate required to play the video?  

For example, 1080p ProRes 422 LT requires about 13 MB/second so you'd want storage media that can maintain about 20 MB/second to be sure that it will play smoothly.

Sorry for not clarifying more, i am working with h.264 and apple ProRes 422 LT also for proxies i tried using the apple ProRes proxy and it didn't help at all. Frame rate is normally either 29.97 or just 30 fps. And the source for the files is either MP4 or .mov. file format is QuickTime. I only have two plugins. My issue is it's not a constant issues, it only happens sometimes. I'll edit for a few days and it's fine then one day it just won't work for hours.

Hi @soren5FE2,

Welcome to the Premiere Pro forums and sorry you're experiencing issues. Echoing @R Neil Haugen and @JonesVid, we need a few more details to try to help with the issue. What kind of media are you working with (what is its source, file type, frame rate, etc) and what kind of proxies have you tried using? Do you have any third-party plug-ins installed?

Sorry for the frustration and hope we can help you soon.
Dani

@soren5FE2 - forgot to ask if your SSD with media is external to the PC have you checked the sustained bit rate ?.

I think 1080Ti will handle H264 but not H265.

@soren5FE2 - as Neil suggests we need to know the media you are using.

Have you tried resetting your workspace ?. 
Some time back I had issues where timeline was very laggy even on a fast machine and that sorted it. Worth trying.

You didn't list media, which would be a very important part of the discussion. As for instance, that ancient CPU doesn't have any internal hardware capabilities for H.264/long-GOP, and I don't think the 1080Ti does ... so any long-GOP is going to be slow especially if 4k or above say 25fps.

Everyone's mileage always varies ...
