Introduction
I've been watching some progamers stream recently, most notably IdrA and DeMusliM, and I was really impressed with how smooth their mouse control looked. I know that whenever I play, my mouse is flying all over the place and I have a hard time clicking reliably on workers, mineral patches, zealots, etc.
I messed about with some settings in the control panel, adjusted the sensitivity in game, fiddled with my mouse DPI (Razer Mamba btw), but nothing seemed to help.
So I looked around for more information regarding mouse acceleration. I found out that in Windows 7 it's impossible to completely remove acceleration without messing with the registry. Even if you turn off "Enhance Pointer Precision", games can still override that! Luckily there is a pretty simple fix that worked like a charm. Once I applied it I noticed immediately how much smoother and responsive my mouse was. It seemed like it was an extension of my hand, rather than a wild beast I was trying to tame (lol).
Step-by-step
1 - First you need to download the registry fix.
2 - Now you need to find the percentage that your display is set to (mine was 100%). Go to:
Control Panel -> Appearance and Personalization -> Display
Find the percentage. (100, 125, 150)
3 - Extract the zip file.
4 - Double-click the REG file that matches your percentage number.
(click yes/ok for the prompts)
5 - Reboot
Now you're done applying the registry fix! But there are some steps you need to take before you're done. First you have to go to your mouse setting and ensure the Windows sensitivity is set to 6/11. Any other setting means you're not getting 1-1 control ie: missed pixels, input delay. Make sure to uncheck "Enhance Pointer Precision". (duh)
I personally set SCII sensitivity to 54%, and play with my DPI to get a comfortable feel, and that's what I recommend you do. If you don't have a mouse with adjustable DPI though, feel free to change this setting as you please, it doesn't hurt.
Done
I hope this guide has helped with your mouse settings, I know it has helped mine!
The Liquipedia entry on Mouse settings is informative, and you should read it if you haven't before.
EDIT:
If at any time you want to undo this fix, go to the folder you extracted the zip file to, and double click the on that says WindowsDefault. Click through the prompts, and restart.
I should also mention that I'm unsure what exact settings pros use, I just find that this fix helps MY mouse control to more closely resemble what I see on their streams!
|
So do you know that pros use this registry fix, or is your referring to them just because you find the feel of it more resembles what theirs looks like?
Great info though, I'll look into it, it looks quite promising.
|
=P I find the feel of it more resembles what theirs looks like. Maybe I'll put that in there so no one gets confused

Still don't get it why i should DL a Regfix for Mouse Accel to prevent the Accel Bug happening with older Games (such as CS). You don't need this for SC2.
http://donewmouseaccel.blogspot.com/2010/03/markc-windows-7-mouse-acceleration-fix.html
I use 6/11 - 54% and have 1:1 in MovementRecorder (without the Regfix ofc). You also don't need this crap for FPS (at least not for the newer ones). Most of those might use build-in other accel crap (like BF:BC2) but there are often other fixes 
|
The registry fix is just a simple thing that every serious FPS gamer should have done or has done already. Bottom line: muscle memory develops quicker and is more accurate without acceleration, because it eliminates a variable (aim speed).
In FPS games, this can mean that you can hit insane 180 degree turn-snipes purely by feel, whereas it's very hard to do the same if you're using acceleration (the speed at which you turn also factors into where you aim, which is far from ideal. Depending on how fast you react, that one crucial headshot is either 2cm or 4cm of mouse movement away.)
I'd say it's a must-have tweak for anyone who is at all serious about gaming. In RTS, the effect might not be as immense as it is in FPS games, but being able to split workers with your eyes closed (because you're made that exact motion thousands of times already) or exactly hit that one ghost you're trying to feedback can make quite the difference in your level of control and speed thereof.
edit: Before we get into that whole debate again: yes. There are pro players who use acceleration and still play well. No one is saying it's impossible to play well with acceleration on. It just takes a lot longer to get to the same level of comfort with your mouse, and your muscle memory is a lot more sensitive to small changes (mousepad surface, new mouse, slightly tired arm, etc...)

it disables it on desktop as well, which if you use 51% in SC2 gives you the same pixel to movement ratio. you can literally increase your sc2 precision just by browsing the internet and whatnot.
|
Of course you don't NEED this for SCII, but it did make a difference for me.
That's where I got this fix from! But I thought it would be nicer if I wrote it up and posted it here, where more people would see it.

Still - use Movement Recorder before AND after. I bet you'll be at 1:1 everytime. You don't need Regfix cause SC2 just doesn't mess with Accel.
Btw: has been posted before ~

You can disable it as well without the fix. Sometimes disabling stuff in Windows settings really does what it should do.

This should have zero effect whatsoever on sc2 unless your mouse acceleration is bugged to be always-on. It was made for older games like half-life where the game would force-on mouse acceleration even though it was disabled in your mouse settings.

Yeah, and then we can insert a guide about how to perform the most trivial tasks through a command line, 100 times the length of that simple 5-step guide.

Not sure if this will fix the problem. But before I try it i have a question:
I read a lot of things about DPI and windows mouse speed ETC trying to get a consistently smooth and accurate mouse motion in Brood War. Eventually I settled on this:
Windows mouse: setting 6
Razer Deathadder: 1800 DPI, sensitivity 10
No other software settings or Chaos plugin mouse tweaks.
This setup is perfect for me and I feel like it gives me the most accurate control.
In an attempt to recreate this feeling for SC2, I also read that I should keep the Windows setting on 6 to retain 1:1 pixel blah blah blah, and 51-54% SC2 mouse setting.
It still feels slightly off though. When I whip my mouse to make a worker mine for example, I come up pretty short and it feels as though my cursor is bouncing off an "invisible wall" towards the end of the whipping motion. Is this negative acceleration? not sure what the problem is.

IdrA and Demuslim both use the Steelseries Sensai, which has negative and positive acceleration built into the sensor in a way that you cant disable or adjust.

Yeah I just bought a steelseries mousepad and my mouse glides like crazy.
Is there one for Mac? Im currently playing on one
|
Do majors LANs allow for players to install this registry fix?
If you are used to playing with the fix it seems playing on a computer without it would be detrimental to your performance
|
MLG has already fixed their registries to remove mouse acceleration. Not sure about other tournies but I'd imagine they do the same.

im not starting anything, but what you said was silly.
Thanks for the link OP, ive been looking for this for a while now, ^^

you do realize that even if one had acceleration, they would eventually get used to it just like any other type of setup? i have acceleration and have no problem selecting individual workers on the fly,...
|
Oh god another one of these threads.
OK OK gimme a moment.
EDIT: Every user needs the mouse registry fix because the option in windows is broken and has been broken for the last ten years.
Everything in the OP looks fine even though there are a million places on the net you can find this.
1 to 1 means you are playing at 6/11 in windows sensitivity. Never go higher. Lower is tricky but also fine.
The liquipedia entry for mouse settings is basic, but acceptable.

Razer Mamba is one of the worst gaming mouse, specialy for RTS.
Buy an Abyssus.

I wouldn't trust something that changes your registry settings, especially if you're using mouse drivers/software, like Logitech SetPoint or Razer drivers. It isn't difficult to turn off acceleration and set the sensitivity to 50% (1:1).
In SC2 options, do you have "Mouse Sensitivity" checked? The slider in SC2 overrides your Windows mouse sensitivity. If you uncheck it, it'll use your computers mouse settings, so if you use SetPoint and have sensitivity at 50% and acceleration off, you'll know it's 1:1. Or if you're just using Windows, 6/11 should work right.
Try toggling "Enable Mouse Sensitivity" in SC2 options. You shouldn't feel a difference if your Windows mouse settings are correct and your SC2 sensitivity is set to ~50 to 53%.
OP, can you open your variables.txt (My Documents\Starcraft II\variables.txt) and tell me the exact value mousesensitivity is set to? If it's above 0.540000 then you don't have 1:1. When you use the slider it can display the wrong percentage. If you slide it to 54%, it could be 53.5% or 54.5%.The default is 50% (1:1), which actually can show up as 51%, and in variables.txt it'll say 0.505050.

If you don't trust a registry file, thats fine. Just edit the registry to the same values.
Also sensitivity at 50 percent is not necessarily 1:1. Again only 6/11 is 1:1.

I use 6/11, no enhance pointer precision, and 64% in sc2 (accel disabled). Anything wrong with this?

but you can't do this at a tournament?

Depends on the mouse. And the registry. And the operating system.

No, there is nothing wrong with that. Your not going to get a 1:1 ratio with your mouse movement, but that won't matter as long as your used to your current setting.
There is nothing wrong with a raito other than 1:1, we don't know if having 1:1 is actully really important in having a good mouse accurac. People just think if there is any mouse movement ratio that is the best its prolly the 1:1, but not necessarily, but most probably by default without any real research. However, if your're going to take in consideration such a minuscule thing as having the most correct 'mouse ratio' there are other things that you also have to take in consideration, like sleep schedule, fatigue, food health, mouse/keyboard equipment, FPS you get on your computer, etc..
Mouse sens is such a minuscule thing, there are lots of more important things in becoming good at SC2, like how much you play, motivation, pratice partners etc..
I think people need to think less about having 100% mouse sens, and just focusing on things that are more important. If you're not already practicing 4-5 hour a day and are have a grandmaster rank, gamesense, macro, micro and etc., then mouse sens does not matter yet.
|
A lot of conflicting information in this thread....
|
Having played a lot of FPS games at a high level, first with mouse acceleration and then with the registry fix, I can definitely say it's better to play with it off. As someone else in the thread says you can of course learn to cope with the acceleration which is something I did. However the slightest disturbing circumstances can put you way off your game, and heaven forbid you take a one week break or it'll take twice that time to get in shape again.

Use the mousemovementrecorder.exe that comes with this to see u don't actually need the fix to disable accel for desktop, sc2 or other newer games(most of them). Even games like cs 1.6 have simpler ways of disabling accel. Some random games are gay tho and need it.

I use mousefix since 2005,and it is a huge difference.

As I understand it it's 1:1 when there's no green or red in the middle, since that's when the device movement matches cursor movement. If that's correct it's 1:1 for me without registry fixes or messing with any settings. Mouse sensitivity was at 6/11 and SC2 at 51% to begin with, though.
From that I guess many of the posters here saying the registry fix is irrelevant for newer games are correct.

Never as well as someone who doesn't have acceleration. Your muscles don't respond exactly the way you want every single time, and acceleration will always be slightly off compared to the previous time. All acceleration in mouse movement is bad because it's an unnecessary variable.

I don't know what it is about my computer, but if I turn off "enhance pointer precision" I can't click shit my cursor just goes flying all over the place.

if your below masters, maybe you should just practice?

Or alternatively, if you're in any league at all you can just perform some easy steps to make playing SC2 more enjoyable/comfortable, and help your long-term improvement in the process.

I wonder if pro's use the auto drift control / angle snapping / correction software on mice these days.
On SS it's called PerfectAim/ExactAim, on razer its no drift control, can't remember for Logitech. But it's basically if you were to draw a straight line in MSpaint it would prevent you from wobbling by a few pixels in either direction so it's a little straight. When it comes to SC2 where you need to have the accuracy to follow in lines like highlighting individual units while moving, or box around something, it might be more beneficial.
Older mice generation from Logitech/razer all had this built in and you had no choice on the matter, whilst MS mice did not. It was a point of mass debate in FPS communities how much this helped with your aim or not and it boiled down to how you felt about it. It does feel really weird getting used to it in a FPS, like you feel have worse aim but at the same time a little more precision if that makes any sense..
I use it off for many years, but thinking about turning it on again for SC2. There's not too many SC" pro's that strike me as real mouse nerds unfortunately, something any quake pro would be on top of his game with.

Thank you Turo for this thread! I barely started using windows 7 and really had no idea what was going on with my mouse control, it felt slightly off, but now it feels way better.

I personally disabled it on my Deathadder. My philosophy, if you can call it that, is that my pointer shouldn't be doing anything that my hand isn't also doing, and drift control breaks that rule - if only by very little.
I could see it become annoying in SC2 if, for example, you had a bunch of marines that were *almost* in a straight line. You'd have to deviate from that straight line a bit to manually select them all, and the drivers would be actively trying to prevent you from doing this. Although, it's quite possible that the function only really activates for very long stretches of equal direction/speed; I don't know exactly how the algorithm works. I just chose to go the safe route and disable it.
|
So let's say I did this registry fix, and mouse speed in windows is 6/11.
1) if i change sc2 settings to above or below 54%, will i start to have innacurate mouse movements?
2) does the rule of "dont put your sc2 mouse settings at 50/55/60/65, etc" still apply?
3) is there a way to change mouse speed in windows to keep it at a 1:1 ratio? i use razer abyssus, and it only has 3 dpi settings, and they dont really give me the mouse speed i want.
thx for the OP info.

Yeah the only thing with acceleration is that you would want to use it in games where the enemy object is moving at a variable speed (like in Quake). There's really no reason TO use it in sc2, but you can definitely get used to it if that's what you are comfortable with. The reason people recommend you remove it at the start though is that it's just easier to learn without it... although I don't think it's really that big of a deal. Whatever works.

Quite the opposite. Playing FPS games with acceleration on is an exercise in frustration.
You are trading off accuracy (the entire point of an FPS game) and consistency for the ability to not have to move your hand for big turns.
If you're a super-high-sensitivity player, fingertip-gripping your mouse and you only have about 3cm of mousepad estate at your disposal, this might be an advantage. In all other cases, you're hurting yourself by turning acceleration on.
Imagine if you were trying to write something, and your lines would become longer the faster you drew them, and shorter if you drew them slowly - even if you moved your hand the exact same distance.
In my case, the loop of my 'L' would be about 10x too high, while my 'R' would be tiny because I write it more slowly than the 'L'. It would take such an immense amount of practice to even write legibly with that.
In a nutshell, that is exactly what acceleration does to your mouse. Your aim is going to be dependent on another variable that is very hard to control. You'll find yourself either overshooting your target, or purposely aiming slower than you could be so you stick to your 'familiar' (therefore predictable) speed. In short, it's a pretty big deal.
Many of the proponents of acceleration on have never played long enough without acceleration to get over the "everything is so sloooow!" phase, or have played with acceleration on for such a long time that they somehow managed to get used to it. That, and a lot of people that don't even know what it is and whether it's on or not.
|
Thanks for the post, I didn't do the registry fix, but I did change the sensitivity to 6/11 (it was a slider, I didn't realize it till I read this post that there are 11 notches), I already had game sensitivity at 54%. I also realized my pointer precision wasn't turned off. After these changes my mouse pointer feels like an extension of my hand, as you said.
great post
|
For those that think acceleration is equivalent after many years of experience I have to disagree. I played unknowingly for 10 years with it enabled and could use the mouse well because of the practice. However I prefer with acceleration off after only a week. Precise movements feel more natural now, since the ratio of pixel to dpi is constant and not fractional. I have had it off for many months now and also turned it off at work, I will never go back.
The reason it is default is because on average a computer user has a cheap very low dpi mouse combined with a very high resolution. Without acceleration the average user would have trouble getting their mouse across the screen.
