Lightroom Classic intermittent slowness after update

[joshn87027797]

No idea what to say really but just everything about lightroom classic is intermittently slow after an update today.

I'll be editing a photo, and adjusting the exposure and it's fast/snappy/good.,.. then the next minute it takes SECONDS to just do each increment on the exposure.

Same thing for using the brush on subjects to de-select areas, sometimes it's INSTANT as it always has been, the next the brush is stuttering around and missing sections you passed over. 

Last weeek I used the AI denoise feature for a picture and within a few seconds it had done it...

Now it's taking an age longer to just do 1 picture, like the best part of a minute on pictures from the same camera (z6, raws converted to dngs on import, so about 45mb DNGs for LR to denoise).

I'd say the above is happening 20-50% of the time, with the rest of the time LR being as snappy as it usually was last week..

Any ideas here on what I can do?

My specs/versions:

Windows 11 - 23h2 (22631.3155)

Lightroom Classic - 13.2

Intel 15-13600k

32GB Ram

RTX 3080 10GB

Hey, @joshn87027797. Welcome to the Lightroom Community. I'll need more info to help you figure this out.

Does this happen after a specific series of steps? 

The Intel i5-13600K has Intel UHD 770 Graphics (Intel's Spec sheet). You have two GPUs on your machine. The power-saving Intel Graphics & the high-performance Nvidia RTX 3080. The drivers for the embedded GPU drivers could be old. Try these steps: 

1 - Update the graphics drivers using Intel's auto-detect program. 

2 - Follow the steps in the content here to configure the default GPU for Lightroom: https://adobe.ly/48KiVVK

This should directly help how Lightroom works.

Let me know how it goes. Thanks!
