Lightroom Classic using all the Vram

[Blue Hasia]

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!

Have you perhaps in Windows OS turned on Hardware-Accelerated GPU Scheduling (HAGS)

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?

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

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.

Thanks for the details. I've shared the details with the team for review. In the meantime, use a catalog that is not associated with any folder related to OneDrive or any cloud backup services.

Let me know how it goes. 

Thanks!

I do my best to disable one drive and my only cloud back up is Idrive set for a once a week scan.

you saying drive made me also think if this might be  something. I have adobe installed on my main C  m.2 drive but my Raw photos are on  my sata SSd.

I would not think that is an issue, i would assume photos im working would go into my 128gigs DDR5 ram.

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.
