This looks to be an issue at Microsoft's end. The API to change the mouse cursors location no longer works.

I have reported it here: http://answers.microsoft.com/en-us/wind ... bd2ad4a90a

Just for the record, I'm using the final retail build (9600), and this is still a problem. Unless Microsoft releases a hotfix post-release, this will still be a problem when Windows 8.1 launches.

You dont need to downgrade your windows.

Search on google for rinput 1.3, its inject dll on the exec to force use directinput work fine here.


exec rinput.exe then type osu!.exe, open osu! and play. =)

Another way.

If Control Panel, Appearance and Personalization, Display shows a 'Smaller...Larger' slider.

Try clicking the 'Let me choose one scaling level for all my displays' checkbox.

Apply Markc mousefix.

work fine with 1 senstivity.

i think osu senstivity change windows sensitivity, then the markc mousefix stop work.

The problem is with mouse rate checker, with mousemovmentrecord and DirectInput Mouse Rate(dimr.exe) they show 1000hz.

I'm still trying to understand what happened here. Has behaviour at non-1.0 changed in test build? Could you make a video?

I feel as though I'm going to have to install a native copy of win8.1 in order to figure this one out. VM just doesn't cut it since I cannot replicate the exact behaviour you are seeing.

PSA: use sensitivity at 1x until this is fixed

Oops i got out of track, we are talking about Win8. Does anyone have a gaming mouse with adjustable DPI? Does this happen no matter what DPI are you using?

Not sure if it fixes the exact issue with osu! or not though.

Edit: Doesn't seem to help. If you want to test it, you have to flag osu!.exe to be affected by the update (instructions under "How to extend the update to other games").

The windows 8.1 mouse fix doesn't effect osu :c.
But, i've found that if you right click, Properties, Compatibility and "Disable display scaling on high DPI settings". It will work for the most part, I do feel a few derps sometimes (could be just me), but it works quite well and is better than nothing.

That update only seems to fix stuttering and/or freezing cursors. I'd assume the fix for jumpy/unresponsive cursor is something separate..

Using DPI is a lot better O.o If you can use DPI and leave osu! at 1,0x.

Well, apparently we can fix osu! by manually extending the update part. The question is should i attempt to manually change it as the instructions say or should i wait until they have a fix fix? Also, does manually adding osu! solve the mouse sensitivity problem?

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.

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.
