Question

Photoshop not using all CPU, RAM nor Graphic Card during rendering - low performance

Hi there,

 

maybe I can find some help here.

When I google this problem I cannot find any suitable solution.

 

I am rendering 1 min. long videos with the newest Photoshop and each video takes 3-6 minutes to render.

CPU utilization of Adobe Photoshop is at around 10% (in total) and not more than 30% highest utilization for the highest logical processor. The affinity is set to all processors.

RAM is around 10GB used and the graphics card is below 5% usage.

 

How can I make that Photoshop utilizes all the ressources available? I wouldn't mind 100% CPU utilization 🙂

 

I already tried to downgrade Photoshop to the oldest available version now available: 21.1.9

I already tried different settings within the performance tab: the memory usage, the cache levels, cache tile size. The file is already set up in pixels and no other unit.

 

 

I am using the following system:

CPU: i9-10900X

RAM: 128GB 3000MHz

3D: GeForce RTX 2080 TI

SSD: TS2TMTE220S

 

Thanks a lot for any suggestions.

    I was experiencing a similar issue recently and unchecking "use openCL" in the gpu settings seemed to fix the issue. 

    its in edit> prefs>performance> gpu advanced settings

    it also brings back scrubby zoom

      There is no such thing, plain and simple. It's inherent in how PS relies on its standard functions and most of them aren#t parallelized, either. That and of course the video functions are kind of plugged on after the fact, anyway, so there is additional overhead or bottlenecks. That aside, on a more general level even more optimized video apps take time for encoding and processing plus there are other factors to consider such as file I/O. In light of that 3 minutes rendering for 1 minute of video is already pretty fast, all things considered. You know, 20 years ago this could take half an hour and we spent days rendering out the simplest stuff. I really think you need to manage your expectations here to a realistic level. Beefy hardware isn't everything...

      I believe the correct expectation should be that a $400B company should be able to update their codebase to take advantage of modern hardware. Given the other apps which Adobe owns, (Pr, Ae), it's not unreasonable to expect that a much faster video rendering engine should be available for Ps to use. 

      BTW, in the past 20 years, the speed of saving .psd files has not changed even though we now have access to drives that are capable of 7GB/s. Sadly, Ps is still only able to save at 300MB/s!

        100%

        I did do one setting change that seemed to help show/hide with layers. It doesn't really help with live response of curves or anything, but if you disable compression of psb/PSD files I think it must actually need less cpu, therefore Photoshop's bottleneck doesn't seem to slow it down as much. Larger cache files, I'm sure, but to me, it's a good trade off. Still not good enough when it comes to live changes in adjustment layers, but at least me toggling most things is a bit faster now. And I had no idea that the write speed was limited! I tried for hours to mess with my SSDs to figure out why they were saving slow or the cache seemed slow. Now it all makes sense.
