Windows users experience sluggish Lightroom Classic - potential solution
This is primarily if you have Nvidia GPU. I don't know what the AMD equivalent is. However, I found a solution to my sluggish LRC. Basically I was getting stutters and lag all over the place. Even just moving the mouse without editing anything caused it to stutter. Turns out it might be a refresh rate issue. This fixed a sluggish Lightroom Classic on both my gaming desktop pc and my laptop.
go to Nvidia Control Panel > Manage 3D settings. Setup a program setting for Lightroom Classic. Scroll down to "Monitor Technology" and select "Fixed Refresh".
Would appreciate if people experiencing the stuttering tried this and see if it helps at all.
