What size (in pixels, not inches) is your monitor?

 

What edits are you doing when this happens?

monitors have width and height ... what are the pixel dimensions width and height?

 

Aslo, what is the size in pixels (width and height) of your original photos?

Graphics card is most useful for 4K and larger monitors, which you don't have. Since you have a very fast CPU, I would try turning off the GPU acceleration in Lightroom Classic (preferences->Performance->Use graphics processor should be set to OFF)

Still, it doesn't make any sense to use all of the vram, photoshop also doesn't work good, even with my old sistem after i've added more than 24 files.

Sounds like you're not even going to try turning off the GPU acceleration in Lightroom Classic to see if the problem goes away.

It's confusing when you say VRAM 23.2. VRAM is the ram on the GPU. Are you talking about your RAM? and what is wrong with that when you have 128GB?  Is Lightroom Classic working normally otherwise? Are you saying LrC is using 23.2 GB of RAM? Is LrC doing face detection or address lookup?

I know the difference and it's vram, because of that if i don't close lr so that vram is free again, i can't use any programs because it will lag horrifing.

He mentioned a 3090, he means vram.... didn't realize it would just gobble up unlimited vram, jeeze, I have a 2080 super with a mere 8gb and it uses all of it the same.

As designed, LrC should use all available VRAM until another application requires a share of same. Unfortunatley, systems with large quantities of VRAM (typically 8GB and above) are not releasing the VRAM. Adobe are currently investigating why the VRAM is not being released in the expected manner. The issue also seems to be more prevalent on Windows systems than macOS.

It's been like this for couple good versions and still not even a little fix. It was working fine with older versions, too bad i didn't check which one.

I'm seeing it too - but I suspect this might actually be by design, and that there's no problem to fix.

 

First of all, this only happens when you have the advanced setting "use GPU for image processing". If you uncheck that and just leave "use GPU for display", the VRAM usage immediately drops.

 

Second, I can see no ill effects from this. It never peaks fully, it always stops at 90% or so. No performance drop, no increased fan, nothing. Everything works perfectly. I wouldn't have noticed if I didn't go look for it. When I open other applications that need VRAM, it's released and they get what they need.

 

I recently replaced a 2GB Quadro P600 with a 5GB Quadro P2200. They both go to 90% and stop.

 

As for the "by design" part - there's an old saying: free memory is wasted memory. It's supposed to be used, it doesn't do anything sitting idle. So maybe that's just what Lightroom does, and there's no more drama to it.

For me there is performance drop and a huge one. If i have lr open with vram at max and start editing in premiere, my system would freeze and can't do anything. Premiere would start using gpu to 100%. 

I don't know what adobe did but i should've note on what version it started this problem so that i would not update.

Have the same issue: https://feedback.photoshop.com/conversations/lightroom-classic/lightroom-classic-vram-usage-impact-p...

 

With a 24GB graphics card it is even worse than with an 8GB graphics card. For now I've set within LR Use Graphics Processor to Custom, selected Use GPU for display and de-selected Use GPU for image processing. LR's VRAM hogging has way too much impact on other programs using the GPU memory as well.

 

Since other programs do not show this behaviour, I'd think that it is not purely an NVIDIA memory management thing, but Lightroom behaviour, or a combination (wondering if people with AMD graphics have the same issue).

I am having this problem as well, all vram being used and then lightroom grinds to a crawl taking anything else running on my computer with it. have to constantly restart the program to maintain any kind of usability.
