That is a useful program.

Hopefully if people are able to more easily build curves they might experiment with custom curves more than they do now (which seems to be hardly at all).

It is good to see other people caring about this stuff.

Hello I need to make my custom curve just like the old auto acceleration in half life 1

can u gimme the numbers I put in custom curve? thx

"Thanks to Mark C. and hoppan for all their related work" indeed!

this is great but only reason im not using it is that im too noob to find adjusting offset, as cl_mouseacceloffset :C

Nice program.

It can be pretty useful, because the default acceleration is too high. This tool helps on touchpads too. Thanks!

Thanx, great tool, espacially for us with lower level of knowledge, it's very user friendly compared to that manual editing stuff.

Thanx again!

Good job! Will check this out when I'm on Windows again.

Can anybody explain to me why i still love CPL mouse fix which gives me more response and accuracy than 1:1 ration with others fixes?

Placebo?

You must have got used to the × 0.78 sensitivity multiplier that CPL has, and real 1:1 feels too fast.

Hi Mark!Its not placebo, i used to had anirs fix, cheesys and others but when i tried CPL on Winxp, i started destroy everything, i really like feeling of it

Mark, i read the guide but i dont understandt it at all, can you give me example how my cpl fix look like in this utility?

CustomCurve.exe displays the values (in decimal notation) currently in your registry when you open it. If you have applied the CPL mouse fix, just run CustomCurve.exe and you'll be looking at the CPL mouse fix values.

CPL will be like:

x1: 0.625, y1: 2.65
x2: 1.25, y2: 5.3
x3: 2.5, y3: 10.6
x4: 5, y4: 21.2

... although the final decimal places on the y values might be a bit wobblier (but the final decimal places don't matter too much).

Notice for that every pair of numbers, Curve Sensitivity = y/x = 4.24, and because EVERY pair has the same ratio, CPL has no accel and a constant sensitivity at all speeds.

Final Windows sensitivity is = Curve_Sensitivity × OS_DPI_Factor × Control_Panel_Pointer_Speed_Slider_Factor / 3.5.

OS_DPI_Factor depends on OS:
- XP+Vista = Monitor_Refresh_Rate / Desktop_Text_Size_DPI
- Windows 7 = Desktop_Text_Size_DPI / 150
- Windows 8 = Desktop_Text_Size_DPI / 120

Control_Panel_Pointer_Speed_Slider_Factor is the "Sens Factor (EPP ON)" column below:


If you have XP or Vista @ 60Hz, then OS_DPI_Factor is 60 / 96, and CPL has a final sensitivity of 4.24 × (60 / 96) / 3.5 = 0.757.

If you have Windows 7, then OS_DPI_Factor is 96 / 150, and CPL has a final sensitivity of 4.24 × (96 / 150) / 3.5 = 0.775.

Mark, is it possible to get your personal help on a matter of acceleration?

Can you please suggest some numbers for a few "smooth" acceleration curves (i liked logitech mouseware acceleration curve on low back in the day, no trying to emulate it)?

I can't find the sweet spot with all those combinations. Please help with some good smooth curve numbers for this method of editing,

Thanx

Values might vary widely from person to person because of personal preference along with system settings. There is alot of discussion about what makes a good curve in the links posted.

My personal settings are:

( 0.5 , 1 )
( 1 , 2.5 )
( 1.5 , 4.25 )
( 2 , 6.125 )

logitech g400
250 dpi
Vista
640 x 480 @ 120hz

This curve is designed around the idea that the mouse acceleration should be felt only at lower speeds to give extra precision with slower movements. I want the curve to quickly taper off towards a more linear shape so that there is little change in effect during medium to faster motions. This helps to make flicks more consistent. Most people that argue against mouse acceleration use inconsistent flicks as the basis of their argument, but most of them only have experience with 1 preset curve.

If I doubled the mouse dpi, I would need to scale the X and Y values by 2 to achieve a similar feel. You could try my settings and if it doesn't feel right, try scaling the X and Y values by 0.5, 1.5, 2, etc...

Using the exponent tool is also an option and a good way to ensure your curve is smooth with a proper concave shape. Y = X ^ 2 is too aggressive for me and I prefer values more like Y = X ^ 1.125 or 1.25. Start with simple X values to start, such as 1, 2, 3 and 4 or 0.5, 1, 2 and 4 and then scale accordingly. I would probably have to scale the Y by about 3 or so to keep the slope in a functional range because of my low dpi. This is all just my preference and based on the same idea where the graph becomes linear quickly.

It can be difficult at first to determine what exactly needs to be done to achieve the feel you want, but it can also be sweet once you start to dial in on it. Hope this helps. Good luck!

its says "Check entries for correct format"

You must have a number between 0 and 65535 entered for each X and Y value before saving. Non numerical characters and blank entries are not allowed.

If you're using the exponent tool, you need to have all four X values entered before using the "y = x ^ " button. If your X values were 1, 2, 3 and 4 and you entered a "2" next to the "y = x ^ " button and then pressed it, the Y values would become 1, 4, 9, 16 respectively. It probably wouldn't feel like a great curve, but is just an example. Try something like y = x ^ "1.25" and then Scale Y * "3". That might give a better example of a usable curve.

i used your settings...

( 0.5 , 1 )
( 1 , 2.5 )
( 1.5 , 4.25 )
( 2 , 6.125 )

Try using commas , as a decimal point.
The program works with whatever decimal point character is defined in the Windows Control Panel Region & Language settings.

Could you help me how to make a curve where the slow sens is without accel and accel gains the higher it goes?

I feel like the initial mouse movement (where it's slows down) makes it harder to trace the target, whereas noaccel is easy to trace with but I'd like the fast accel for turning and dodging flashes etc.

Can you make settings for me, I'd like to try yours, but for 800dpi, 60hz and 500hz usb polling rate.

can you do that for me. please?


If it isn;t possible, than 125hz polling rate.


Thanx

There are likely too many variables and your in-game sensitivity indirectly affects any accel you feel using a curve.
We don't know your in-game sens or bologna's in-game sens, so can't be sure about how bologna's curve will feel for you.
(The same applies to the Windows Control Panel 'Pointer speed slider' sensitivity, but you are both probably using 6/11...)

The biggest problem with matching your setup to bologna's curve is that you use 500Hz polling rate.
AND we assume bologna has a 125Hz mouse polling rate...

Can you increase your mouse DPI to 3200?

If you can, do so and use this curve:

( 0.5 , 1.25 )
( 1 , 3.125 )
( 1.5 , 5.3125 )
( 2 , 7.65625 )

AND ALSO set your Control Panel pointer speed slider to the 3/11 position (3rd position from the left).

What's going on with this curve?
To make the accel the same, the X values (ideally) have to be the same). The X values are the accel thresholds and determine when accel kicks in. The Y values are how much accel to apply.
So it has the same X values as bologna's curve.

Your polling rate is 500Hz, which is 4 times more frequent than bologna's (assumed) 125Hz. This means more frequent but SMALLER mouse movements, which makes it harder to hit the X thresholds. The fix is to multiply your mouse DPI by 4, 800DPI × 4 = 3200, so that larger values are compared against the accel X thresholds.

But then your overall sensitivity would be wrong, so multiply the Y values by 0.25 to adjust overall sens back to 800DPI.
But what about sens when 'Enhance pointer precision' is OFF and the curve is not being used? Set 3/11 which gives × 0.25.

But Bologna uses Vista @ 120Hz, which doubles overall sens, and you use XP/Vista @ 60Hz and/or Windows 7, which does not double, so multiply by 2 to get the same as bologna.
But we are using the curve at 3/11, which multiplies by 0.4 WHEN EPP is ON, so divide the Y values by 0.4.
0.25 × 2 / 0.4 = 1.25, so all of bologna's Y values are multiplied by 1.25.

Bologna's mouse DPI is 250 and yours is (effectively) 800?
I don't think that matters, and the curve doesn't need adjusting for that.

You might check out some of the curves here: http://www.esreality.com/post/2321616/natural-logarithm/
... which are fairly low [Edit: Oops fairly high by the look of it] I think.

Thanx guys, I'll try those options later and let you know how it worked. Nice to see people trying to help...

Two questions:

1) Why would anyone want acceleration? Any at all? This blows my mind.
2) What kind of games do you play where you still need mouse fixes? QW and Q2?

Acceleration is very useful on the desktop, particularly for people that have multiple monitors.
Being able to tune the accel is a good thing.

Is there a way to force acceleration across all applications, windows AND games?

I think I made a good enough curve....thanx for helping me, guys.


But many games seem to ignore it. Is there a way to force it?

Thanx

Is there a reg or file i can use to disable mouse accel in windows 2003 server?

Or what can i use?

Can I get a sanity check on my first curve (that feels right)?

x = [2, 3, 4, 6]

then used the scale/exponent tool at a factor of 1.78 for final values of:

(2, 3.434)
(3, 7.068)
(4, 11.794)
(6, 24.272)

Using a Zowie FK @ 2300 dpi, 1000hz on a 1440p multi-monitor setup.

I use claw grip and previously used 2300 dpi without any curve at all.

edit: just kidding, that curve felt HORRIBLE in-game. now tweaked and gone with

(3, 8.97)
(3.3, 11.06)
(3.8, 15.09)
(4.5, 21.89)

think I'm getting the hang of this now

If anyone wants a claw grip, 1440p (running @ 105hz) setup, I find this one to be extremely good now! After a ton of fidgeting and messing around.

(1.7, 2.89)
(2.2, 4.84)
(2.6, 6.76)
(2.9, 8.41)

Using the max DPI setting on the FK.

I know this is too much to ask, but I'll try, maybe it will be a challenge for some expert here :).

Here are the old Logitech MouseWare drivers

http://www.majorgeeks.com/mg/get/logitech_mouseware,1.html



I really, really liked their acceleration curve on low setting and mouseware forced it everywhere.

I used logitech mx500 and mx300 back then, but i guess it doesn't matter.

I'm asking for some expert here to extract the archive (winrar or whatever) and look for some values which could be for acceleration curve they use (on low setting). They must be stored somewhere.

I'd really like to try to replicate that. I'd kill for those values.

I know this is too much, but this is ESR afte all ;)

Thanx in advance.

I have found a bug: My locale uses a comma instead of decimal dot. But loading the default values will enter the values with decimal dot causing the values to be horribly off.

Cant use that programm..
In win7 it is worked normal, but not in Win Xp (Sp2).
What to do?

Creedence Clearwater REVIVAALLLLLLL

I think it's the same as Povohat driver

** System Requirements **
-------------------------
Windows Vista and up (i built it with WDK 8.0, sorry XP users :< RIP)

If you install .NET Framework 4.0, it should work OK on XP:

http://blogs.msdn.com/b/dotnet/p/dotnet4xp.aspx

Is there a way to figure out which acceleration curves Logitechs SetPoint software uses? It gives you a few options, like low, medium.. and so on.

I'd like to have Win7s mouse accel behave as if SetPoints 'low' setting were active, without having to use that software (since it only works for supported hardware anyway). Any easy way of doing that?

I remember someone saying it's pretty much like quake 3 accel. If you asked this a few months earlier i would have been able to give similiar povohat driver settings. But im not using acceleration anymore and don't remember what i did. But shouldn't be hard to figure it out yourself. If you want some variation in logitech acceleration. I suggest installing setpoint 3.1. (compatibility mode) When using "setpoint inplementation" and using something like 7/11 or 8/11 instead of 6/11 sensitivity, it will give some nice sensitivty cap like acceleration. Logitech removed sensitivty scaling with setpoint inplementation in later versions. (probably due to acceleration effect) In more recent version these settings would just give staircase/ripple effect.

I'm quite happy with SetPoints current accel when it's set to 'low'. The thing is that I want to reproduce it on hardware that's not supported by SetPoint.

Whats your logitech mouse and whats the DPI step you are using with accel low. Also what setpoint version are you using.Just curious.

It's a K400r (wireless with touchpad) with the latest SetPoint installed. I'm just trying to reproduce the very same acceleration behavior with a similar keyboard that is not supported by SetPoint.

Not for gaming and not for myself, but you don't get these kinds of questions answered elsewhere, it seems.

Then i don't see why povohat driver with some (random) acceleration setting (and some getting used to) wouldn't do it, if it's not for gaming anyway.

Bologna, space why can't you receive judgements

I surely can't be the only one that just wants XP's EPP dynamics for games that don't allow direct input from windows and only accepts raw input from the game.

You can also remove mouse acceleration for older games that automatically enable it (such as quake 2) by entering a linear graph similar to:

( 1, 4)
( 2, 8)
( 3, 12)
( 4, 16)


hello I like ur post, it might get me back on track
u said to remove acceleration for older games I write these

what if I want to enable acceleration just like in old games what numbers I should put?!

I rlly need to fix it I was pro in counter strike half life and now I suck :D

what the numbers I have to add to the custom acceleration so I can get old acceleration in half life 2?

I used this in 2022 win11 and it destroyed my settings
mouse moves 10px max every time
still trying to recover

u wot m8

this is concerning
