Lightroom Classic performance and Logitech wireless mouse: my experience.

[FelipeRF Fotógrafo]

Hello everyone,

I’m writing this message in case it can be of help, as in my case it has made a radical change. I think I’ve read all the threads about poor LC performance, as I have a quite powerful PC (Ryzen 9, lots of RAM, SSD drives, decent graphics card) and yet, LC was driving me crazy with its lack of smoothness (in module changes, when moving from one image to another, in creating or editing masks, in using the brush with the Wacom tablet…). I tried everything, to no avail, and I even installed the trial version of Capture One (which, by the way, was much more agile than Lightroom).

Well, yesterday the Logitech MX Ergo mouse broke down and I replaced it with a cheap, optical, wired one that was around the house… And it’s been incredible! For some reason, the wireless MX Ergo (I hadn’t used another with my PC) interfered with Lightroom and made everything very slow. Removing it has impressively increased LC’s performance. Yesterday I thoroughly enjoyed editing photos, retouching masks with the Wacom brush in a completely fluid manner, and seeing how any change occurred instantaneously. I would have never imagined that the darn mouse could have such a tremendous effect on LR, but that has been my experience, and I share it with you in case it can be useful to someone.

And, BTW, no more wireless mouses for me, thanks.

Greetings from Seville!

Logitech MX Ergo

Was the connectivity via the Logitech Unifying USB Receiver (dongal) or via Bluetooth?

If Unifying Receiver, perhaps a USB port conflict.

Lightroom Classic has been driving me nuts lately whenever I've tried to crop photos. It's been a tremendous hassle to drag corners, etc. I tried switching out my aging Logitech MX wireless mouse with a cheap wired mouse, and that solved the problem immediately.  Your post confirms my own experience!
