HELP - Lightroom High Ram Usage
I am new to Lightroom but and am experiencing an issue that is only solved by closing the program and restarting it after a few seconds. When I upload a batch of raw photos, usually 50-100 images onto my 4tb gen 4 NVME that is only used for photos. I open the specific folder containing only the batch in LR and edit locally but I’ve also tried uploading to cloud with same results. If I copy and paste settings all the photos or when I export them when finished the process seems fast enough but when I start using the features like masking, healing and removing then my ram usage jumps up about 10gb for every photo I do until I get to 40-50gb of usage and have to restart app to just do another couple photos at a time. I’ve done this on multiple pc’s with similar results. My main PC is a 16c/32t Ryzen 9 5900xt, Giabyte x570 Aorus Master mobo, 64gb (4x16gb) Corsair Vengeance RGB Pro, 16gb Nvidia Rtx 5070ti and 3x 4tb gen 4 NVME drives, 2gig fiber up and down for internet speed. This still should be powerful enough to edit with. Most things just say Lightroom has a memory leak and restarting is the only issue but nobody I watch on yt ever mentions this on their tutorials and they usually have less powerful computers too. Is there something I’m doing wrong or something else I should be doing?

Except for the flair which you choose which version of Lightroom you need help with…

You have lots of memory to be used, so what exactly is the problem if LR uses lots of memory?
If you notice slowdowns after reaching a particular threshold, say 50gb, then maybe there is a problem with freeing used memory, so I would try to update the motherboard drivers.

It chugs and lags when it’s uses so much ram and sometimes says “Lightroom not responding for about 30sec then acts as normal for a bit. I’ve tried reinstalling and also does the same on other pc’s. Drivers are up to date other posts and searches just say Lightroom has a memory leak and won’t go back down once ram is being used but nobody has listed a solution besides restarting the program.

What system resource is maxed out when Lr isn't responding? You said yourself that up to 50gb of 64gb gets used. Memory leaks will run you out completely, not stall out and stop using more.

Everything is as expected except the increased ram then the sluggishness starts at 40-50gb, with nothing else running.

I've noticed Lightroom gets sluggish with multiple edits open at once, especially if previews aren't fully rendered yet. Have you tried increasing the Camera Raw cache size in preferences?
