Report: Windows 8.1 causing heavy mouse lag in some PC games

Deus Ex: Human Revolution is one of the games affected by the Windows 8.1 update.

If you are a heavy PC gamer, you might not be happy with Microsoft's recent update to Windows 8.1, depending on which games are on your hard drive and which mouse you own. Online reports have come in that claim updating to Windows 8.1 can make some games unplayable due to an "improvement" in handling DPI for multiple monitors.

In this case, according to a post on Reddit, the changes in the DPI framework have caused games that don't use Raw Input or DirectInput to get hit with a massive amount of mouse lag. Among the games that are being affected by these problems are Deus Ex: Human Revolution, S.T.A.L.K.E.R.: Call of Prypiat, Metro 2033 and some games in Activision's Call of Duty series. It also seems to affect hardware that includes mice products with a high polling rate and high DPI.

We have emailed Microsoft to see if they are aware of this issue and, if so, do they have plans to fix the problems in a patch. In the meantime, the Reddit post has some rather complicated instructions on a possible workaround but it may not work for all games that are affected by this latest issue with Windows 8.1.

I think, Microsoft must adopt one standards and add support for gaming mouse with more than 5 buttons. It is wrong, especially in MMO games when you have to take combinations from keyboard and assign them to the mouse trough special drivers.

No issues here so far; Diablo 3, HL2 et al, entire Assassins Creed series to date, BF3, Dead Space, Dota 2, Orcs Must Die! 1 & 2, Portal & Portal 2, Unreal Tournament 3.

windows 8.1 seems to be really picky with drivers and software compared to windows 8.

I did a clean install of 8.1 on my system and I have some problems with programs not working correctly even though they worked with no problem in windows 8.0

I just tried Deux ex and it run great in 8.1 on my system.

So we're getting all worked up over what is probably a very small percentage of users, based on a Reddit post mind you, and promoting that its a major issue? Every OS has a small percentage of users with just the right combination of software and hardware to experience problems. Nothing new here, this has happened with XP, Vista, 7, and 8.

This is a pretty large issue. Breaking compatibility like this is not a good thing. It was signaled in the preview and should have been long fixed before the release.

Where's your stats that it is a large issue? Half the posts on the Reddit topic are people confirming they don't have the issue.

I knew Windows 8.1 will be buggy as ever. I'll wait and see..what Microsoft does. Once it;'s stable enough perhaps than I will upgrade it without the hiccups.

I have very little issues with Windows 8.1 save for a few quirks that I can't understand from a design perspective. I don't even see the mouse issue that is mentioned here... XD Maybe I don't play the games that others do.

Buggy as ever? Based on a few people on Reddit having one issue? I guess every launch of every product ever know to man has been "buggy as ever" for you then.

If you're releasing a GA it shouldn't contain silly and stupid bugs that are noticeable especially when they have been reported too but wasn't fixed.

And yes, buggy as ever, I give credit where it's due and bash/criticise where it's due and should be just as when Apple released iOS 7, buggy as ever. BSOD, crashes, etc, etc.

I can confirm this! When you playing CSGO and you disable RAW opstion in game mouse start laging!

There is lots of people complaining about this on all gaming forums i hope Microsoft will fix it soon!

Interesting. Last week when i updated my Windows 7 and added the new nvidia driver. I also has weird mouse lagging, even on logout. The mouse cursors would even change. I solved it by roll backing the graphics driver and doing a full scan with Malware bytes, which removed some malware. Don't know what caused my problems, but this sounds a little similar.

I think you are confusing Microsoft with Apple. Nice try though.

Think you're confusing apple with the US government

I would imagine it probably graphics card drivers or mouse drivers that are needed to be updated, not really something Microsoft need to fix with the os.

Set your game exe so its compatibility level is Windows 8 and disable scaling on high DPI settings. If you're having mouse problems from multi-monitor DPI scaling, that fixes the issue. (Admin elevation may be required)

Not using DirectInput for games running windows is idiotic.

I have razer mamba/naga (very high dpi + high polling rate). No issues.

Do you even promode?

Raw Input is where it's at.

Raw Input and DirectInput are pretty much the same thing and neither have issues.

And they were trying to tell me that 8.1 is recommended for gaming.

Nope, i'll stay with Win 7 a bit longer I thinks!

All the titles listed are older titles. I would expect most current games to use the standard apis rather than polling the mouse directly. I'm sure Microsoft will come up with a workaround in the meantime but I do think the compat option is the best route.

Indeed it makes it easier for all your opponents.


LOL now it is true that the mouse lag and performance issues with 8/8.1 will literally get you killed

And how many of these users use "specialty" mice with high polling rates and high DPI settings (as opposed to standard mice from Microsoft, Saitek, Logitech, etc.) and their drivers (as opposed to the more "generic" drivers included with the OS (or even Microsoft's own drivers, which work with a surprisingly large number of non-Microsoft mice)? One reason I have eschewed Logitech's SetPoint (Logitech V220 Cordless) is because it has too many features I'll never use and is just plain "porky" - and that was under Windows 7; the Windows 8.x version is just as porky - no thank you. Instead, I used first IntelliPoint (Windows 7) and now the Mouse and Keyboard Center tag-team in Windows 8.x (I also have a Microsoft Wireless Keyboard 6000 V.3) - MKC (Mouse and Keyboard Center) is skinnier than the IntelliPoint/IntelliType Pro tag-team it replaced in Windows 7. And I have exactly zero issues in gaming.

Thank you for putting up this up. I was just about to upgrade to Windows 8 but I might just stick with Windows 7 for a bit longer.

The issue in the article is already known to be resolved by setting an app's compatibility level to Windows 8 and disable scaling on high DPI settings, so it's a minor problem with a resolution (Article says running as Admin also required, but I'd try without that first). You probably don't need to use this issue as a variable in your upgrading decision.

Not true, that might work for some games but I already tried doing that months ago because this problem has been around since 8.1 preview. And still doesn't work for me in the final version.
Edit: meant to reply to Kaedrin

Another indication that the Windows-8 UI was not designed with keyboard/mouse interaction being the principal method of data entry/interaction with one's PC. Oh well.

Another pointless troll post.

An added note here. If setting to Windows 8 doesn't work try setting to Windows 7 instead.

Apart from the fact that this issue is caused by DPI improvements made for multiple monitors. Those DPI improvements are for the Windows desktop as well. One of many desktop improvements in 8/8.1 over 7.

But hey don't let facts get in the way. None of you Win 8 haters ever do. You're always wrong, uninformed or plain stupid.

The level of stupid in this post is simply mind boggling, especially considering the feature in question is only ever useful or necessary to users who use the Desktop. Tablet users with a single screen are never going to see or use this feature.

If being older than a 25-year old kid makes one a "troll," so be it.

Well the statement appears to be something to incite debate over a factor of the UI that has nothing to do with the article.

For the most part the UI works fine on desktops and while I do acknowledge the issues that others have had I don't see any usability issues personally. I use Windows 8.1 as a daily driver (have done so since RTM showed up on Technet) and I appreciate it.

Also this is for multiple monitor setups which might explain why I never personally saw it. If you don't use multiple monitors then there shouldn't be much to hold you back yet.
