Langsamer Export seit Lightroom Classic Version 11 . CPU Auslastung gering.

[default6znrqchzk3ni]

Hi.

Seit einiger Zeit (ab Lightroom Classic 11) läuft der Export recht schleppend. Auffällig dabei, die CPU-Auslastung der 12 Kerne liegt maximal und nur kurzzeitig bei ca. 40%. Früher lief die CPU während eines Exports mehrerer Fotos mit nahezu 100 %.

Vorab vielen Dank!

I'll help you figure this out. I'll need more info. The GPU driver on your machine is version 516.94 & the GPU is supported to be used at export. Please update the GPU drivers first & then follow these steps:

On Windows, the GPU info & Logs location is %APPDATA%\Adobe\CameraRaw. A shortcut to get to this folder on Windows is:

• Press the Windows + R
• Enter %APPDATA%\Adobe\CameraRaw
  
• Rename the GPU & Logs folder in this directory by adding .old at the end. (GPU.old & Logs.old)
• Restart Lightroom Classic, which should capture the updated driver & hardware capabilities.
  
  

If the above steps don't help, share a screenshot of the export settings you are using, the type of image you are exporting & how much free storage you have in the C drive.

Thanks!

Hi Sameer K,
thank you for your support. Unfortunately it didn't solve the problem. The max CPU-workload during export still remains at around 30 - 40%, so the export needs more time than normal (screenshot attached).

GL_VENDOR: NVIDIA Corporation
GL_VERSION: 4.6.0 NVIDIA 528.49
GPUDeviceEnabled: false
OGLEnabled: true
Free storage at C-Drive: 331GB of 464GB

Export settings ataached.

By the way:

The export settings refer to .cr3 (Canon R5 RAW File) to jpeg.

"User preference: GPU for exporting enabled"

"The max CPU-workload during export still remains at around 30 - 40%"

Your preferences have enabled the option Preferences > Performance > Use GPU for Export. Your screenshot shows CPU at 40% and GPU at 14%:

That's typical when LR uses the GPU for exporting -- CPU usage is reduced and GPU increased (but LR never seems to use more than 15-20% of the GPU for exporting -- it still has to use the CPU for much of the computation).

Use a watch or the computer clock to time the export of 40 photos, with and without the option GPU For Export enabled, and let us know the times.  Sometimes LR is slower when it uses the GPU than when it doesn't.

Thanks John,

i did the test you recommended to me.

Export time of 40 photos (RAW to JPEG) without using the GPU (disabled): 1:03 min. CPU stays at 100%

Export time of 40 photos (RAW to JPEG) GPU enabled: 30 sek. During export the CPU is about 30-40%, GPU max 39%.

Printscreens attached.

"Export time of 40 photos (RAW to JPEG) without using the GPU (disabled): 1:03 min. CPU stays at 100%

Those results look normal -- 1.6 secs/photo without the GPU, 0.7 secs/photo with the GPU.  On my 3.5-year-old Macbook Pro 8-core Intel i9 using an AMD Radeon Pro Vega 20 4 GB, I observe about 1.2 secs/photo, with roughly similar CPU and GPU usage.

When using the GPU, it may not be possible for LR to use more CPU than what you observe (39%), because there could be other limitations, e.g. memory bandwidth with the CPU and GPU.  But that's just a guess.
