That fix completely solved the issue for me. I can select sensitivities well above 1.0x without getting jumpy cursors like I was before I applied the update. I applied the registry fix, did the ShimFlushCache step, then rebooted and that fixed the problem. Mouse also seems slightly more responsive as well.

I notice that osu! seems to be taking longer to load with the fix, but that's a really minor issue compared to jumpy mouse.

Updated (11/8)

We want to thank our gaming community for the detailed feedback many of you have provided on these issues. We have released some fixes and workarounds that will allow you to get back to your gaming.

The “mouse lag” issue is actually several different issues that could vary based on the game, input methods used, etc.

The three following issues are addressed by a fix we have provided in KB 2908279:

Mouse jitters (jumps forward and back) as you move it through a game
– This occurs in some games because Windows 8.1 introduced changes to mouse input processing for low latency interaction scenarios and this causes some games to respond differently to mouse input than in previous releases of Windows.

Mouse movement is not to scale even after acceleration is turned off
– If you have turned off acceleration to make the distance on the screen match the distance you move the mouse, that may not work correctly anymore.

Measured mouse Polling Rate has a lower reporting frequency than expected
– If you have a gaming mouse that has a high frequency, when you test it, you may find it is reporting a lower frequency than you expect. Note: if you previously encountered issues with measuring the polling rate you will need to follow the instructions in KB 2908279 to ensure that, not only the patch is installed, but also the app used to measure the polling rate has an appropriate registry entry to enable the fix for that specific executable.

- Run osu! 8.1 Mouse Fix.reg to import the registry entry
- Run ShimFlushCache.bat
- Reboot

osu! 8.1 Mouse Fix.reg contains:

I am on Windows 8.1, do I need to install some Windows update manually? If yes then from where? Also no I havent done the hotfix I thought it was in the fix you sent let me try it with the hotfix first. Thanks for help.

EDIT: It worked after I installed the hotfix, thanks for help I can finally play Osu! at uni.

Just did a clean install of 8.1, didn't get the update automatically.

I wonder if the update gets offered if you happen to have one of those games it mentions installed, but I doubt it.

What if I have problems with my mouse stability and sensitivity on a non-Windows 8 OS? Because I'm not really sure if it's just the mouse's laser len thing or the program itself, because it used to work perfectly fine with osu.

It did not work after following the steps in the solution.
But then, i tried to put it in compatibility mode for Windows XP (Service Pack 3) and it worked perfect.
