LrC lags my PC after exiting

Every time I close LrC my computer becomes incredibly laggy. My mouse cursor skips about the desktop and, if I have music playing, it skips as well as though I'm at 100% CPU utilisation.

 

If I open task manager to see if I am in fact at 100%, the behaviour ceases and my machine begins running as normal until the next time I open then close LrC.

 

Does anyone know how to fix this? Although I am able to get rid of it by opening and closing task manager, I'd prefer a permanent solution to the root cause of the issue.

Try turning off the GPU option in LrC and test.

Exiting Lightroom Classic after editing some photos

No screenshots

CPU: intel i5 4690k

RAM: 32gb corsair ddr3

This problem only began ocurring in the last month or two. I had no issues before then. This also does not happen on my laptop using the same version of LrC and a GTX1050.

This seems to have fixed it. I turned it off and tested it twice with no lagging behaviour afterwards.

451.67 is my Geforce driver version (latest) and my Camera RAW cache is located on my C drive which is one of my faster SSDs.

 

The fix from Just Shoot Me to turn off GPU acceleration seems to have solved this issue, though I'd prefer to have that on.

Ok, but a performance tip

 

Try to avoid placing the Camera RAW CACHE on the same hard drive as your Windows OS Paging file, as they will compete with read/wrights to the same drive. This of course would require an additional hard drive, and yes the Camera RAW CACHE benefits from placement on faster hard drive. so, a trade off, fast C drive vs slow D drive, you would have to experiment.

 

I think that the Camera RAW CACHE gets purged at LrC shut down, so one thing activity wise occuring st thst point.
