Thread Ripper Stutter Playback

I managed to talk to someone at Adobe who can do things on Reddit today. Here is what I posted in regards to this issue. This was his response: 

Great! We got some actual traction on this issue today, mainly due to your fine post. We now have an internal bug filed and hope to have some test cases shortly. Resolving issues like this do take time, but we are now on a path to assisting you and other users with this setup.

There was another user on uservoice who said he had a tech support rep tell him that the engineering department was working on unspecified "this issue." From this it sounds like this is not something that they were previously aware of and that the other user's rep was talking about something else or something similar. The good news is maybe this will actually finally get fixed!

I am having this same issue on my system - Ryzen TR 1950x, 32GB ram, SSDs, the works. I built this system specifically for video editing and so far my crap Lenovo i7 laptop does a much better job. Here is a video of the two systems playing back the same clip:

I should note that in this test, the laptop is loading the footage off of a network drive while the 1950x system that should be awesome is loading it off of a super fast RAID 0 with read/write speeds above 700MB/s. I also tried loading the footage from a fast SSD with the same results. It's NOT a read issue, it appears to be a CPU issue.  

I get jobs where I edit with clients and I have already lost one job and put another in jeopardy because of this issue. I look like a (*&#$ moron being $3500 into a pro editing rig in a pro studio and it performs like flaming garbage. 

PLEASE PLEASE PLEASE: I encourage everyone who has this issue to report it a bug here and cross your fingers that Adobe pays attention and fixes this.

I have the exact same issue - no matter what I do, nothing plays back smoothly. I've reduced playback resolution as far as it'll go, I've made Cineform proxies for my entire project (even tried playing those back at 1/8th resolution!), and it still drops dozens of frames over just a few seconds of playback.

My system is a Threadripper 1920X, 32GB of RAM (3400MT/s), a GTX 970 and a Samsung 960 Evo drive + a 4TB HDD.

I've tried placing both the project and the media on both drives, I've tried both GPU and software accelerated playback, I've checked every resource there is to check (RAM use never exceeds 80%, SSD load never nears any type of choking point, and outside of creating the proxies the CPU barely seems to be lifting a finger - same goes for the GPU). I'm utterly baffled by this.

My media is from a Sony A7S II, XAVC S 4K 100Mbps 25p files. I get that these files might be a challenge for Premiere (even if VLC plays them back just fine), but I can't grasp why playback with 720p Cineform proxies wouldn't fix this.

Any and all help would be greatly appreciated, as this is driving me up the wall right now. Editing is impossible when playback doesn't work.

I feel like this problem is never-ending. Everytime I think I have it fixed I open a new project and it starts all over again. Adobe needs to figure this out because it's not a problem I'm having with any other program. This is an Adobe problem.

I was having the same issue with stuttering of video playback in CS6.  My new build (1 week old) was almost identical to yours. I began my research today beginning with your question.  In reviewing the threads I tried the bench mark tests suggested by Bill G and in doing so found that my CUDA card/settings were not being recognized by Premiere so I downloaded the NVIDIA Cuda Toolkit that installed some drivers.  I then followed a tip from youtube where the "cuda_supported_cards.txt" file needed editing to include "GeForce GTX 1080 Ti" . Once I restarted my system and launched Premiere it recognized my card and allowed me to select Mercury Playback Engine GPU Acceleration.  The stuttering has stopped.  Bill H.

FIXED!!!

With all the research I had been doing it seemed the audio hardware was the issue. I updated my audio drivers and also installed ASIO drivers base on my motherboard, and it has seemed to fix the problem.

Let me know if this works for anyone else.

I had the same issue and I found a solution that worked for me.  I can now play h.264 footage, xavc-I, and 6K R3d footage with easy with no stutter. This worked for me.  I had to disable HPET with "false"

After I did this my whole system was stable running Premiere

[/cmd admin

to enable HPET - bcdedit /set useplatformclock true

to disable HPET - bcdedit /set useplatformclock false

bcdedit /deletevalue useplatformclock

I own a very similar system. 1950x, 64GB ram, Gtx 1080ti, m.2 boot drive. My fs5 .mxf files

shot at either 4k or even HD, playback choppy. Very disappointed. My old Mac Pro

5,1 with a Gtx 980 plays smoother. Transcoding to cineform has fixed the problem. It's a problem with premiere because in VLC playback is fine. Everything else is crazy fast but the SINGLE most important thing for editing, just sucks. Too bad we can't ProRes

on windows :-). Cheers. Mark.

I suggest that you test your system with my Premiere Pro BenchMark (PPBM) which will tell us how well your CPU, GPU and storage system are operating.  Please download and run the project, it is self instructing and then Submit the results. I will get back to you.

I'm wondering about this:

jayk02  wrote Two problems of note: Welcome screen sits upon launch for up to 20 -30 seconds before plug ins load.  Once they start, the program is up 2 seconds later.

This seems to have happened after 2017.0.2 which is version on my previous computer, and the new one started already with the .1 upgrade. The screen that pops-up when the program is started - in v.0.2 the program loading items start scrolling by almost immediately. On my new computer (with much faster m2 drives) it takes 9 seconds before the items start scrolling. Quite disappointing really... is this just something adobe changed or could it be only on mine and to OP's computer?
