Enhance details not using gpu

Hey guys,

I'm using a Intel Xeon SixCore E5 1650 v3, 32 GB ECC RAM, nVidia Quadro K4200.

If I apply "enhance details" to 100 RAW files (Canon 1D X Mark II), only my CPU will be used (100%). My GPU is sleeping. Yes, LR finds and uses my GC ;-)

Of course, my system has the very latest updates.

Can anyone explain that to me.

Thanks!

Your GPU is probably not supported for this feature: https://helpx.adobe.com/lightroom-classic/kb/lightroom-gpu-faq.html

Well, actually the card should be supported because it meets the minimum requirements. But it may not work anyway.

I'm not an expert in this area, don't know that ins and outs of Lightroom programming, don't work for Adobe. However, "maybe" the enhance details feature isn't programmed to utilize the GPU. As I understand it, GPU utilization is primarily there for 4K and 5K monitor users.

The Enhanced Details feature is definitely programmed to use the GPU. It even warns you in its dialog that it may be slow if you don't have a fast (and supported) GPU. It's possible however that this feature has different requirements than the general GPU acceleration of the Develop module.

I also think that there are different requirements that are not communicated.

Have you tried updating the Nvidia graphics driver? The latest version for the K4200 is v431.70 released July 29, 2019. My Nvidia P2000 GPU shows 100% usage and CPU ~25% when using Enhance Details.

Of course. I think the card, although it meets the requirements, not supported.
