P: Bring back the ability of Enhance to run in the background. (LrC)

Are you a bot? Adobe Employee, really?

Why would you remove the abilitiy to mass enhance photos within Lightroom (Cloud based)?

Whoever thought of it as a good idea, is definently not a professional. ..and for anyone suggesting copy pasting a setting (in our case, Denoise), I have news for you: I did that and yet, I have to go through each photo to update setting for the Denoise to be applied properly.

I work with thousands of photos - do you understand my frustation? I'm sure I'm not the only one. 

If they had anticipated this result, they should have given users a choice in the program settings. Now they can only revert to the old version.

I can accept that the computer will slow down during the AI ​​denoising process, but after the AI ​​denoising is complete, the image will still be severely lag, which is unacceptable.

What are your computer specs? GPU? CPU? CPU memory?  RAM? OS version?

@KANG KR I would point you to the pinned reply by @KrishnaMaithreya here where they say: "these models are currently designed assuming they can take over the entire GPU". I expect you'll be told that taking up excessive CPU/GPU usage (even when loading, likely due to not having a preview built) is something you should expect.

I've observed that when using the new noise reduction feature, clicking on a picture with noise reduction completed instantly fills up the CPU, causing the entire computer to become very slow. The new non-destructive noise reduction feature places extremely high demands on computer performance. I hope to be able to choose the previous method.

The new version of LIGHTROOM's AI noise reduction function does not require generating separate DNG files, which makes editing the denoised images extremely choppy and far less smooth than when generating separate DNG files before. Can the original separate DNG noise reduction files be restored?

I just updated to 14.5 Saturday and took some wildlife shots this morning. For some time now I've been shooting Auto ISO. Since Denoise I have been happily selecting the 5 or 10 keepers and then running Denoise at 100 as a batch. I just tried doing that today and Denoise will neither automatically manage processing the selected group, nor let me adjust the amount at all, initially! When I let it complete the first 1, there was a message on the screen about using Auto Sync and it finally let me adjust the amount. After adjusting it I tied various things with setting auto sync but nothing happened. Finally I tried manual Sync selecting the 'new' denoise option. I do not consider this an improvement but a 'technical  issue'.

Also, as mentioned before, when Denoising a new image I'd really like to be able to set it to create a DNG file to keep.

I would prefer the destructive new file creation over this image by image denoise. This method has made huge impct on my productivity and has impacted my ability to deliver event images in a timely manner. It has negitivly impacted my business and I will need to move to a new tool in order to have quality TIMELY denoise. A compermise might be that you create a 'Batch Denoise' feature that brings back the DNG option for those who need a more timely solution.
