I have been struggling wiht LR Classic since upgrading to the latest versions (15.0 and 15.0.1). I have follwoed all of the recommended fixed, including turning off automatic changes XMP, adjusting settings in NVIDIA to "prefer maximum performance", increasing cache size to 30, etc. I never had these issues before the upgrade, and nothing has changed with my computer. I have Windows 11 Pro, 64 GB, Dell CPS 8940.

At this point, LR Classic is nearly unusable. As an MFA student trying to get my work done, this is a huge problem!

Correct answer Per Berntsen

From your system info:

Adapter #2: Vendor : 8086
Device : 4c8a
Subsystem : 9c51028
Revision : 4
Video Memory : 80

This is an integrated GPU – Intel UHD Graphics 750.

LrC doesn't like multiple GPUs, so try disabling it by going to Control panel > Device manager > Display adapters.

Richt click the Intel UHD Graphics 750 and choose Disable.

For the record, I find version 15.0.1 to be faster and more responsive than version 14.

In fact, I can't remember any version running so smoothly, and I've been using LrC since version 2 in 2008.

Many of us have reported serious performance issues with 15, but I have not seen anything official come back from Adobe.

I went back to 14 and all is good.

I tried Per's suggestion. It worked seamlessly for my first pic. With the second photo LRC froze AGAIN! Please tell me the best way to roll back to 14. Thanks.
