Lightroom Classic 11.5 has ground to a halt
I've searched for discussions on this, but can only find stuff relating to some while ago.
I very recently (Oct 2022) underwent an auto update in Windows 10 and my Lightroom Classic 11.5 has become virtually useless. My regularly-used catalogs are quite large (in excess of 200,000 photos), but this hasn't been any problem whatsoever up to now. My system is i7, 16Gb RAM, 4Gb graphics card, oodles of drive space. I regularly update the nVidia display driver, so that is at the latest version it can be. All was working fairly smoothly (with maybe a recent - last 12 months - perceivable, slight loss of performance as the databases got bigger) until this recent OS update. I have set options in Preferences to lean towards performance with a cache of 15Gb. However, most times the program doesn't launch. I have to repeatedly restart the PC and then when it does launch it goes so grindingly slowly that I lose the will to live. It is mind-blowingly slow; uploading new photos takes a minute per photo, often more - the software seems to hunt around on the SD card (reformatted every time used) and load images in a random order, whereas it used to always load them in the order they were taken - switching over to the develop module can take 30-60 seconds - switching folders takes ages, when it used to be instant - the imported photos are not displayed in the library as the upload proceeds, they just appear at the end - the list goes on. I've set up a new catalog with only a couple of hundred images in it and all of these problems still apply, so it cannot be caused by the size of the catalog.
No other programs on the PC seem to be affected in any way whatsoever. The PC is easily capable of handling all except Lightroom with blinding speed.
