Dear community,
I am very sorry to open what must be the 1000th thread about laggy playback. But maybe someone can quickly set me on the right track before I search the internet for hours.
I just purchased an used HP-Z820 workstation for quite a low price. I was hoping it could improve my editing workflow (which is horrible right now since I'm working on a laptop). It was quite an impulsive buy though, not much thinking it through, shame on me. Now I'm afraid it was a big mistake, because playback is even worse than on my laptop! (which I thought to be impossible). Seconds pass without me seeing one single frame.
Here are the specs:
Windows 10 Pro
Adobe Premiere Pro CC v12.0
2x Intel Xeon E5-2630v2 @2,6 GHz, 6 cores each
32 GB RAM
Nvidia Quadro K4000 3GB
128 GB SSD [OS & Premiere]
2 TB external hard drive, USB 3.0 [media]
Footage: XAVC-S 4k from a Sony a7sii
In Task Manager, during playback:
CPU: mostly around 20%-50%
RAM: ~11 GB in use
GPU: 4% - 5%
HDD: mostly 30% - 80%, peaks up to 100%
I did a little test project with some files on the SSD to see if the external drive might be the probem. It's better, but not smooth, and I think the improvement is because of the low complexity (I just threw some random clips together whereas the other project is an actual edit in progress (not yet graded though, only occasionally Warp Stabilizer))
I updated the driver of the GPU and activated CUDA acceleration in Premiere, but it looks like the GPU does no work at all?
Any ideas on this? Would be very thankful to hear some opinions whether it's just the old hardware that's not suitable or if I can do something about it.
Btw, just out of curiosity I exported an XML of the very same project, files still on the external HDD, and opened it in DaVinci Resolve. Instantly I get an ok playback with the occassional dropped frame, but nowhere near as choppy.. (I would like to stick with Premiere though!)
Best wishes,
Johannes
