LR Classic slowly grinds to unusable

As the title says LR gradually slows as I edit after about twenty photos it is basically unusable if close reopen or give it a break it seems to figure itself out. I have tried messing with the RAW cache right now I have it up to 100GB which seems extreme. The catalog and cache are on a m.2 drive. I have tried playing around with graphics card settings turning them off on running in auto and have done all the usual changes except switching to smart previews but since it works okay initially that seems like that would not necessarily fix it. The only thing I am seeing in task manager is high GPU utilization and I do a lot of masking so could it be my GPU just can't keep up with all the new AI features? Open to ideas. The computer is Ryzen 3600 32G ram sabrent m.2 and 2060 12g and 4k monitors. The photos are craw from an R7.

Thanks GoldingD, I actually found the issue and I do not think anything I showed you would have told the story as it was pretty unique to me. I have a pcie nvme card so I can run two additional nvme drives. Apparently, when you set that pcie lane for bifurcation it sets all lanes to the same bifurcation. All that to say my graphics card was only running at x4 instead of x16. I made changes and performance is back to where it was. I still am seeing the AI functions like masking beat up on the old 2060 but it is not making me want to throw the mouse. Thanks, sorry for the delay in reply

Also, as an afterthought.

 

  • Is this computer a desktop, or a laptop? i.e. can additional internal drives be added, can the GPU be changed, Can more RAM be added (probably A-Ok just now)
  • What other hard drive do you have? i.e. can files be moved off drive C, can the CACHE be moved off drive C.
  • How much free space in percent exists on the hard drive your catalog is on? i.e. better than 25%

Please post your System Information as Lightroom Classic (LrC) reports it. In LrC click on Help, then System Info, then Copy. Paste that information into a reply. Please present all information from first line down to and including Plug-in Info. Info after Plug-in info can be cut out as that is just so much dead space to us non-Techs and it takes up vast amounts of scroll space making the reply less readable and less likely that others will bother with your post.
