P: GPU used even if you deactivate it when exporting and confirm to LrC not to use it

Dear all

 

Windows11

LrC 13.0.1

 

Step to reproduce. 

 

1) Activate GPU. Select several photos with development. Export them. Look at your resource monitor for GPU

 

2) Deactivate GPU. Restart Lightroom. Select the same photos. Launch the same export 

 

3) A warning message tells you that the GPU is deactivated and ask you if you want to activate to speed up export. Press cancel to keep it deactivated. Look at you resource monitor for the GPU. The GPU and GPU memory is used anyway

 

 Kind regards

    @SYNDICATE Rob, "The difference in export speed is just so staggering on my machine from 12.5 to v13 that I can't ignore it, with my average weekend export often topping 20k images."

    I'm starting to think a permanant rollback to 12.5 might be in my future, but that obviously creates some conflict with needing to access existing v13 catalogs.

    The difference in export speed is just so staggering on my machine from 12.5 to v13 that I can't ignore it, with my average weekend export often topping 2k images.

    I reported an equal bug already in October and it was ignored!

        In LR 13.1, I observe correct behavior: The GPU is not used for exporting raws when Preferences > Performance > Use Graphics Processor > Use GPU For Export is unchecked.

            I don't disagree, just odd seeing 0% on GPU stats

              Basically i believe this means GPU is used. And you have the same bug, 
              You have same export speeds (more or less) regardless if use select GPU or NOT.

              If GPU wasn't used you should see CPU usage close to 100% (or 90% if you have a bottleneck in HDD for example) and GPU usage close to 0%.
              If GPU is used, the normal is to see both CPU and GPU around 30%.

              so in version 13.x your speeds are basically the same regardless if you use GPU or not, and CPU usage is ~25% this indicate that this setting makes no changes. 
              While in version 12.x this setting gave you almost 15-20% speed boost. (46sec vs 55sec)

              Interestingly enough, my GPU isn't being used at all on v13.0.x regardless of acceleration on/off. v12.5.1 was fine.

              5900x, rtx 2080, 980 pro, 64gb RAM @ 3600.

              Times to export 100 images to ssd:
              v13.0.1 GPU OFF - 1:41.96 (20% avg cpu 55 deg)
              v13.0.2 GPU OFF - 1:41.81 (24% avg cpu 55 deg)
              v12.5.1 GPU ON export- 47.07
              v12.5.1 GPU IP only - 53.46
              v12.5.1 GPU FULL OFF - 53.24
              v12.5.1 GPU FULL ON - 46.9
              v13.0.2 GPU FULL ON - 1:39.93
              v13.0.2 GPU FULL OFF - 1:40.39
              v13.0.2 GPU FULL ON - 1:40.76
