Lightroom Classic using all the Vram

For a long time now, Lightroom has been using almost all of my VRAM. This problem has affected three different windows PCs.

My main editing PC has a 4090, and Lightroom will start using 22-23 gigs of VRAM in less than 10 minutes while editing just one photo! I have to restart the program frequently to dump the memory.

I don’t want to disable GPU acceleration, but why is there no option to limit how much VRAM the software is allowed to use?

My previous PC had a 2080 with only 8 gigs of VRAM, and I was still able to edit R5 RAW photos without any major issues. other than needing to restart a lot to dump the vram.

Yes, I keep my drivers updated. This issue has affected me for possibly 1-2 years now across different PCs.

From what a few people have told me, this is a Lightroom problem because the software by design is to use all the VRAM it can get its hands on. But how does no one see that as a problem? When you hit 90%+ VRAM capacity, the entire PC slows to a crawl!

@AJarosz Newest drivers. ...
DirectX: NVIDIA GeForce RTX 4060 (32.0.15.8115)

This is why we always ask to see System Info. That driver is a 10-month-old Game Ready Driver, and there was at least one other report of LR crashing with it:

https://community.adobe.com/questions-675/lightroom-classic-14-5-1-keeps-crashing-983323?sort=oldestFirst#comments

Nvidia and Adobe recommend using Studio drivers with creative apps like LR. Download the latest version from here:

https://www.nvidia.com/en-us/drivers/details/272766/

It may not fix your issue, but updating to the latest Studio driver is always the first step.

so that might be some issue on the Nvidia drivers side, as I switched to studio drivers about 5 months ago, and last time I was updating my driver 3 days ago... version of the driver seems to be different here to what my Nvidia panel shows.

LR is just reporting what Windows is telling it, so this may point towards a problem. Trying doing Nvidia’s clean installation, as described in step 4:

Still see exactly the same behaviour. LR seems not freeing up resources on VRAM. When GPU acceleration enabled, even if only for dispaying pictures, it gives boost in performance untill I used brush/mask on 3-4 photos. After that all VRAM is taken and LR became very slugish. HAGS is on on Windows. Newest drivers. Ryzen 5800x, 64 GB RAM, 4060 RTX 8GB, 2 separate nvme drives for LR - on one I have library, on the other pictures that I currently processing.

Please do the LR menu command Help > System Info, click the Copy button in the upper right corner, and paste into your reply here, so we can see exactly which versions of hardware and software LR thinks you're running and important LR options that are set.

HOW DO WE GET SUPPORT! im told to post my issues here but nothing happens to help my issue!

this happens on many different PCs for me over years!

I had a look at your workflow videos and noticed that you're using the brush tool in cases where the Subject or Object mask would likely be faster and require much less use of the brush tool. Historically, the brush tool used in the fashion and to the extent that you've used it has always been a memory hog due to the way brush edits are cached in memory.

Still having this issue every day, need to restart light room CC as the Vram builds up so fast and lags my pc to a snail pace.

I have that turned off already, My laptop and prevoius PC i know i never diabled that setting. I remember turning HAGS off on this PC i am using at least 16 months ago. and more likely was adobe related reasons as i never have had game issues.

Hey, @Blue Hasia. Thanks for joining the Lightroom Community. I'll help you figure this out.

Is Lightroom Classic Sync enabled? If yes, We can figure out more with the Diagnostic report. In Lightroom Classic Preferences > Lightroom Sync Tab > Press and hold the ALT/OPT Key to generate a Diagnostic report.

Generally, you can log in to Lightroom Web (https://adobe.ly/3uv2zCA) and look for the Sync Issues category near the Deleted section on the left part of the screen. If there are any Sync issues, check the file name & the original upload source, apply small edits or tags to these images, and wait a while to check if the edits sync to the cloud.

Additionally, check this detailed response from our Expert: https://adobe.ly/4g6Cb4j

Let me know how it goes. Thanks!

I dont use any synch features and i honestly can not tell if this means it is on or off?

https://prnt.sc/iJvZfz-gHTYE

this site doesnt allow html uploads which the diagnotic report saved it as so i put the file on my dropbox

https://www.dropbox.com/scl/fi/d6e8isdfrabrh1xyzv55g/lrsync_log.html?rlkey=gt6kcj5r7n1fsmj03ceezgr6g&dl=0

Here are also two videos of me doing my editing. i have a hardware info in real time in the upper left and can see my vram just creeping up and had to restart each one to dump the vram as when it gets to yellow orange my pc just bogs down and lightroom is like 1 FPS to work with at times.

i uses an R5, R6 and now just got an R5 mii. all with Craw.

its getting so bad now i need to reboot lightroom for pretty much every photo i edit and even more than once per photo.
