Premiere CC 2018 Threadripper bad scrubbing performance

So I started having problems recently with Premiere Pro CC in the timeline scrubbing aspect.

I have a Threadripper 1920x and nvidia 1080ti, 64gb ram on Windows 10. Premiere is installed on an M.2 OS drive.

I also have a scratch disk, 512gb Samsung Evo Pro SSD.  This is where my previews and media cache go.

I edit a lot of XAVC-S footage natively and usually have no problems whatsoever.  Which is what I'm currently editing with in this situation.

I noticed importing a GoPro Cineform clip into my project from a Resolve Roundtrip, premiere would start to get crazy scrub lag.  You would think this codec would be buttery smooth as an intermediate codec.  I could not even zoom in on the timeline without having to press play and waiting for a few seconds before the change would occur. I would play my timeline, and would not be able to stop the timeline from playing. My Timeline would actually disappear on some occasions (just a grey panel).

I came to this thread, tried a few things such as toggling on/off the play audio during scrubbing (this did absolutely nothing).

I did a clean install of premiere. Nothing changed.

Tried playing at 1/4 resolution. Nothing.

I noticed someone said creating different folders for their audio media did the trick. Literally, all I did was create a new bin, drop the cineform clip in, and boom, smooth scrubbing and playback. IDK what the heck is going on with threadripper and premiere, but this is getting ridiculous.  Hopefully this temp fix works on other projects and this is not just some fluke. Keep this in mind.

Love/ Hate relationship with Premiere.  Almost about to completely switch to Resolve especially since the Resolve 15 announcement.

I have been having these issues with a similar setup as well. Threadripper 1950x with gtx1080 card. After literally months of troubleshooting, buying new drives and components, re-installs, and trying every little tip and trick on the internet, Adobe support helped me narrow down the issue to the graphics card. There is a problem with gtx 10 series cards specifically on Threadripper platforms in Premiere (I have not seen this issue on intel platforms with the same video cards). 

To test this, open up Device Manager. Open up the Display adapters section, right click on your gtx10 series card and click update driver. Select "Browse my computer for driver software" then "Let me pick from a list of available drivers on my computer." In the list of drivers that comes up you should have an option for "Microsoft Basic Display Adapter." Select it and hit next to switch to that driver. 

Your resolution will suffer, but once it is installed go back into Premiere and see if you have problems. For me, all problems are fixed.  

Upon realizing this I ran out to Best Buy and picked up the last video card they had on their shelf, an AMD Radeon RX 550 and threw it in my computer. Playback and scrubbing was still crappy until I actually disabled my gtx1080 entirely. Now I can reliably reproduce the issue my toggling my gtx1080 from disabled to enabled in device manager.  

If you all run the same test with the same result, please report the bug to NVIDIA here: NVIDIA Driver Feedback|NVIDIA

Hopefully they can get a fix out to us sooner than later.

Hey all,

I've learned some things in the last month since building a Threadripper 1950x system. Here is a list of things I have done to increasingly improve the performance of the Threadripper in AE and Premiere. Its not perfect yet but its getting faster the more I tweak certain things

FIRST THINGS FIRST FOR PREMIERE***

DONT CONVERT A PROJECT FROM AN OLDER VERSION!!!! It causes major playback issues. Create a new project from scratch OR import your project into the new version of Premiere and copy the old composition into the new comp.

THEN TRY THESE:

1) USE AN M2 drive for your cache!!!!!! I tried using a fast Intel SSD for my cache in After Effects (and Premiere) and noticed that the computer I use at work using an i7- 7700K was MUCH faster than my TR 1950X. Part of the reason is because it uses a Samsung NVMe drive for its cache. I changed my cache to run off my of seperate NVMe drive and the performance on a vector heavy project increased by almost 20% or so. **THE M2 DRIVE NEEDS TO BE SEPERATE FROM THE OS AND STORAGE DRIVE

2) UNINSTALL RYZEN MASTER!!! It messes with your CPU processes. Once it was removed Premiere and After Effects performance improved.

3) CLOSE OR UNINSTALL ASUS SONIC STUDIO. It messes with your CPU processes. Once it was removed Premiere and After Effects performance improved.

4) DONT USE THE RYZEN POWER SETTINGS!!!!! Use PERFORMANCE POWER SETTINGS. Trust me

5) If you are working on a complex After Effects comp with vector elements TURN OFF 'SHOW LAYER CONTROLS'. This speeds things up significatly

6) USE AN M2 FOR YOUR OS AND APPLICATIONS!!!! The faster the M2 the better.

7) UNINSTALL ASUS AI SUITE or any overclocking utility. This processor is a different animal from INTEL, it doesn't work the same way

8) SET PROCESSOR AFFINITY TO 12 CORES FOR AFTER EFFECTS.....this should increase performance for now

Follow these steps and your Threadripper will start to perform like a dream. KEEP IN MIND, this processor is AHEAD OF ITS TIME and Adobe needs to catch up to these new massive multi-core processors. In time After Effects and Premiere will scale with hyperthreading and your system will CRUSH. AMD has started something interesting..dont throw in the towel. The best is yet to come

SPECS

Samsung Pro M2 for CACHE
...the rest of the peripherals dont matter

I hope this helps. I'm still tweaking and I'll post any discoveries I find. Bless!

Buy folders I mean folders inside the premiere project if I have all my video files in music without organization in bins. Timeline will freeze up.

They are on my c drive in video folder? Where should they be?

Are the previews at 100% on both computers? What is the screen resolution on both machines?

I have a threadripper 1950x a 1080ti gaming SC Black Edition and a 960 Pro boot 512gb. Scratch files going onto a 1-terabyte wd blue. I noticed that every time I add an audio file Premiere starts to freeze up and I cannot do anything. The play head freezes up and I cannot move the mouse sometimes. It is very strange if I delete the file from both the timeline and the folder it will go back to normal. I've noticed if I make folders for the music it goes away. Can anyone explain why this is happening? Note I'm very new to premiere! Only 2 months under my belt I bought this computer just to get over not being able to use the program on my laptop.

I have another update.

My main media was being accessed through the network, so i tried moving things to a local drive (stardom raid 5 drive, it is still a slow drive but its local). I found a very slight improvement but still not ideal, and again using a marker to scrub yielded very smooth scrubbing. So it got me to thinking to turn off "play audio while scrubbing" (edit>preferences>audio> then untick "play audio while scrubbing").

Then boom, buttery smooth scrubbing.

This is quite weird as my cache drive is raided ssd's reading and writing at 500MB/s plus.

I do prefer to have audio scrubbing on, but in this situation i'll forgo that for buttery smooth scrubbing.

Well, hopefully this helps as somewhat of a work around. Good luck

HI, im having the same issue.

I want you to test something to see if it mimics my results.

Drop a marker on the time line then grab the marker and scrub.

Im finding im getting terrible scrubbing performance even with proxied media, but when i drop a marker and scrub the marker it scrubs as i would expect it to (nice and smooth). This suggest to me some sort of optimization issue.

Let me know if this works for anyone else.

It has to be a Premiere/Ryzen/Cuda problem. Outside of Premiere I find all videos play fine, even 4K phantom vision but in Premiere 2017 or 2018 it is unusable.

Premiere 6 plays fine. What to do?
