I have a stationary photo computer with full capacity for running LRC 12.1. For doing a rational photo work with LRC I use two computer screens, one for LRC (Screen 1) and one for something else, for example a browser (Sceen 2). The problem that arised some monts ago is that when I move the mouse cursor from Screen 1 to Screen 2, LRC immediately starts to consume 20 % CPU capacity. When I move the cursor back to Screen 2again, the CPU capacity goes back to 0 %. If I do this and simultaneously edit photos in "Develop", the CPU gets stuck and I for example have to wait 15 seconds for magnifying a photo from "Fit screen" to 100 % size (the size of a typical raw photo is 60 Mb). I have tried different mice, but no change. Please help!

As a first step, update your graphics driver by going directly to the manufacturer's web site:
https://helpx.adobe.com/lightroom-classic/kb/troubleshoot-gpu.html#solution-4
If that doesn't help, please copy/paste here the entire contents of the LR menu command Help > System Info -- that will let us see exactly which versions of hardware and software LR thinks you're running.

Thanks for a prompt response!
I have tried all possibilities you refer to, but without success. At the end, the recommendation I got was to install a new graphic card... So, is it that bad? If you have any other recommendation, please let me know. My system info is attached below.

Your graphics card is eight years old, which is very old by GPU standards. It might well be the cause of the symptoms you're observing. Try these troubleshooting steps to narrow down whether the graphics card is the problem:
1. Set Preferences > Performace > Use Graphics Processor to Off. Do the symptoms go away?
2. Set Preferences > Performance > Use Graphics Processor to Custom, with Use GPU for Image Processing unchecked. Do the symptoms go away?
3. Unplug the second screen (the one you don't normally run LR on), with Preferences > Performance > Use Graphics Processor set to Auto. Do the symptoms go away?

When I move around the cursor over the LR screen having "Use Graphic Processor" in Auto or Custom, the CPU usage is 10-15 %. When I turn Use Graphic Processor off, the CPY usage drops to about 5 %. I see no effect of turning the second screen off. So, the answers are:
(1) Partly.
(2) No.
(3) No.
I have searched internet without finding anyone with a similar problem...
A strange thing I noticed now when changing back and forth is that the appearance of the cursor change if I have Use Graphic Processor in Off or Auto/Custom mode. In Off mode it looks like a normal windows arrow cursor. In Auto/Custo mode the cursor appearance chang from normal to one as seen from the side when being moved over the menue or the LR contol panels. Could this indicate something?

Those results do suggest that the problem is the very old graphics card, though I can't say with 100% confidence. Keeping it disabled in LR is probably the best option if you're not planning on updating the card.

I suspected that! Thanks anyway!
