Does anyone have a solution for the cursor lagging the PC mouse movement then suddenly catching up, in other words a jumpy mouse cursor?
Not sure what caused this issue. Done a couple of Windows Updates during the last month or so & noticed that my task manager became sluggish when I load or exit it & now this cursor problem.
Have tried a bunch of the solutions offered on the internet, like changing the pointer options in mouse properties & updating drivers, but nothing works.
Any constructive recommendations will be appreciated. TIA

Thanks guys for your responses.
Have tried all of your above suggestions but problem still occurs - I switched from wireless to wired mouse & switched USB port still no help. Have run several virus scans too & nothing comes up.
I'm using Windows 8.1 on a Dell XPS 8710 with a multi monitor setup using NVS 510 graphic cards. There's lots of memory though - the computer typically has over 50% of the 12GB ram unused. This is a real head scratcher for me, but I'm suspecting the Windows Updates. I'll uninstall the last few updates if I don't make any headway by the wkend. Thanks again![]()
Maybe your computer is mining bitcoin/monero in the background.

You're going about it quite logically, and my own first-thoughts have been covered by others. I have one last idea: check the memory cache allotted for your major activities, and make sure that they're not bumping up against their allotments. For IB's TWS, this is a single line in a plain-text file.

When things get gnarly, your computer might be set up to prioritize TWS and take resources away from mouse.dvr -- so you try to "fix" the mouse, but miss that it's a symptom.
Let us know how you make out!
Thanks for your response.If you have dogs/cats and your mouse has an optical/laser sensor opening .... you might check to make sure there isn't a hair in there. 1 hair is enough to make the mouse act wonky. If so, just blow it out. Happens to me all the time.
