Erratic Sluggish Performance with Top of the Line PC

Looking at your attachment, some items pop to mind

_____________________________________________

Services
Malwarebytes Service

Do you have multiple anti virus running? Is this one causing issues?

Windows Power Scheme
Active power scheme: Balanced

From the Motherboard, I take it this is a desktop, not a laptop, From the CPU I take it this is not a Low Power Use unit. Why are you holding Windows Power use back, You might consider setting that for Best Performance.

WIN ACCOUNT
OneDrive: C:\Users\John\OneDrive

I will not get into a discussion on why using a Windows Account is so so bad. And do not trust Microsoft on that. However, as such, you are using OneDrive. Basically forced by Microsoft to do so. Oh OneDrive can be helpful, but I would recommend a Local Account (OneDrive can still be accessed on a  local account). But moving on, the question/issue at hand as that relates to LrC. If you bring up in LrC the System Information (Help/SYS INFO), is your library path pointing to OneDrive? That Can be a big problem, especially if OneDrive (a Cloud Service) is having issue.

Looking for this (Ok):

Library Path: C:\Users\John\Pictures\Lightroom\Lightroom Catalog.lrcat

not this (Bad):

Library Path: C:\Users\John\OneDrive\Pictures\Lightroom\Lightroom Catalog.lrcat

GPU
4095MB NVIDIA GeForce RTX 3060 (ASUStek Computer Inc)
Driver version: 31.0.15.5161

That driver is not current. You really really should update it.

The VRAM is Ok for current LrC, although some AI features may be a bit slow (DeNoise comes to mind).

RAM
64.0GB Unknown @ 2800MHz (40-40-40-80)
Total memory slots: 4

Used memory slots: 2

Free memory slots: 2

I assume that is 2 sticks of RAM, And have you made sure they are in the correct slots. If this computer was put together at a computer store, or it is a Prebuilt PC, then probably yes. If home built, double check. If wrong I would expect issues outside of LrC. I ask because a YouTube video is in the back of my head. Check your Motherboard Manual for this info.

BIOS
Brand: American Megatrends International, LLC
version: FH
Date:12/14/2023

hmm, I think that is fairley recent, probably not an issue. You would need to check that out at the Motherboards support pages. Updating the BIOS is not for the faint at heart, Probably not for non techys

Intel ChipSet drivers

I could not figure that one out. A old chipset driver can lead to issues, You would need to check that out at your Motherboards Support Pages. Not sure if you have a GIGABYTE application to check that. I bring that up because of a lesson learned.

Not in the attached scrennshot (or I overlooked)

• Your catalog, what hard drive, C or D
• The hard drive the catalog is on, how much free space in %? Looking for at least 20%, some say 25%
• You stated 2 hard drives, correct?
• The Windows Paging File, I assume it is on drive C (Default), that brings up the next..
• Your Adobe Camera RAW CACHE, what hard drive is it on? On a Windows PC, if possible, on a drive other than the one with the Paging file is reccomended (well, by some)
• And the Camera RAW CACHE, what limit in size (praying it is not the way way under size default of 5GB, hopeing for at least 20GB)

Try turning off the anti-virus for a while.
