Noticed this almost immediately coming from windows 7 to windows 10. There is some severe mouse lag in both windows and any applications. This is incredibly noticeable, and a huge issue with gaming in particular. Doing some research shows that windows 8.1 also had very similar issues – why these were not fixed I’m not sure, but I need to get this working now. This kind of issue is the thing that will ultimately turn every gamer into an avid protester.

What I’ve done to mitigate/attempt to fix this problem so far: 

Disabled all vertical sync features, which are known to cause mouse lag. It is disabled in my graphics card settings as well as the fullscreen application I was using to test this, Counter Strike: Global Offensive. 

Updated all mouse software and drivers. 

Applied the Mark C windows acceleration patch for 8.1. This visibly reduced the lag, however, did not remove it completely, leading me to believe this is either an issue with mouse acceleration built into windows, or that Windows is limiting the mouse’s polling rate. The lag is still too severe to play games with.

Tried various fullscreen ingame settings. Even enabling Mouse Cursor in CS:GO, which is supposed to force raw input(ie, 1000 hz polling rate, no acceleration, and no lag) does not fix the issue. This option works on my windows 7 PC to completely remove acceleration and lag – it works flawlessly. This computer previously had windows 7 and also experienced no delay or acceleration.

I tried installing the Windows patch that fixed the windows 8.1 settings, however, it would not install(no option to try compatibility mode) and therefore was not an option.

If anyone has a temporary band-aid fix for this, I would appreciate it more than I can express in text. For Microsoft reps reading this… give us a raw input option built into windows, call it the gaming option if you must. No acceleration, no DPI scaling, no poll rate limiting. A very vocal set of users would be absolutely ecstatic and this is a feature that would be very widely appreciated.

I had the same problems with the lag/pausing or skipping of the mouse and pad across the screen. I stumbled upon the solution by accident and experiment. If you have synced a laptop with the screen of a home network computer, right click on your screen/display and choose “personalize”. Then disable the slideshow or whichever setting you share with your home network. Once I chose just a picture instead of the slideshow, the mouse lag completely stopped.
