Had same problem. Went to control panel, mouse, Smart Sense, set filter to 0. It was set at 3. So far so good. I was ready to go back to 8.1 because this was so bad. I will re-post if mouse gets squirly again. Seems like my old mouse
A number of people are reporting issues with wireless mice.. esp. Logitech mice- maybe drivers- and finding distance helps. E.g.
Solved Really Bad Mouse Lag - Page 3 - Windows 10 Forums
Thank you Dalchina... this was exactly the remedy for my problems. I had the very same problems. Pointer lag (both mouse and touch pad) and later I realized that even my keyboard had same issue. Only when opening task manager the problem disappeared. I had Windows 8.1 bundling with the Acer Laptop and took the advantage on upgrading to Windows 10 on the first day I had my new laptop. Two months without problems until in one morning it updated bunch of patches for 2 hours and the problems starting to show afterward.
Tried everything from as simple as restarting, disable the non microsoft services, disable the non microsoft shell extensions, updating the firefox and all its addons, reinstall my laptop drivers (downloaded from Acer official website), and even (sorry) swearing to my misery...
None of the above worked, until I just disable the FMAPP.EXE and prevent it from restarting under start tab.
Whoala! Solved the problem which almost cost me to go back to Windows 8.1 I had earlier.
I had this problem and felt that there was something running in the background eating up both processing capability and memory. I upgraded the memory which helped a little for a little while. Then it got bad again. I felt strongly that it was Macafee causing the problem. So finally I removed Macafee and installed another security suite. A WORLD OF DIFFERENCE! It's like a new computer. Hope this helps.
I actually removed windows 10 because of this issue.. Then recently my mouse died so I thought maybe that it was because my mouse was on its way out..
So I put windows 10 back on after getting a new $100 mouse and still experience mouse lag.
So annoying I cant figure out why it is happening.
Same problem started happening with me a couple of weeks ago. Running 10 on an I7 with Malwarebytes, which is essential IMO. First noticed it happening when Malwarebytes was cranking (30% cpu), so thought that was problem. But now happening whenever. Cannot install the Intellipoint patch since only good for 32 bit OS.
Looks like another MS failure, like the Office 365 Quick Access Toolbars sized for somebody's thumbs.
You could try eliminating anything that could conflict.
Compare a clean boot with normal boot, and if necessary, safe mode with normal mode (although presumably specialised mouse drivers would not be loaded).
On that basis decide what to try next- e.g. you could try clean boot + disable unnecessary drivers.
In other words, detective work and a process of elimination.
If you upgraded from Win X, try imaging what you have, and a clean install. You can always restore your image again.
Thanks. But not what I was hoping for. I dont have time to spend a day fiddling with my machine. I do have an image from a month before loading AutoCAD 2016, but I don't want to have to go through all that exercise. Not being an IT guy, what is a clean boot, vs. safe mode?
