Switch mouse DPI with keyboard?

14 Jul 2017, 15:32

Hey, I need a script that would let me to switch mouse DPI with keyboard. I do have a mouse that can switch DPI by own key, but I want to be able to do it with keyboard. Is it possible? Mouse is Logitech G203 and it's using Logitech Gaming Software(not SetPoint).

Little bump, got way behind without answer. I've seen many scripts being posted here but I would like it know if there's anything for changing DPI directly, not windows mouse sensitivity or using workaround like great "evilC's" script.

No, to my knowledge this is not technically feasible.
To which of my scripts are you referring? The demo on the MouseDelta thread can only add DPI when the script is activated, however I have a new script which can effectively subtract DPI

Yeah I was talking about mousedelta. This is the problem, top is delta, middle is delta in sniper mode and bottom is same mouse with DPI switch. From left to right DPI400/800/1200/1600.

I would be really interested to see the results of a similar test with the C# version of MouseDelta, I think it may be a fair bit better.

I got problems with launching it, CLR library missing.

See the comment in the first post:

You will need CLR.ahk from here
For each demo, extract the SharpDX DLLs from this post, plus the MouseDelta zip for that post into the same folder

Yes, it doesn't work this way. CLR.ahk doesn't launch, MouseDelta.ahk drops CLR error. Also even if it would launch, not sure how to change DPI.

You are not meant to launch CLR.ahk, it is an include for the script.

You want this demo, and you want to play around with this function in that script:

Code: [Select all] [Download] GeSHi © Codebox Plus

MoveEvent(x, y, mouseId){
Global mdw
if (mdw.SelectedMouse == 0 || mdw.SelectedMouse == mouseId){
DllCall("mouse_event",uint,1,int, x ,int, y,uint,0,int,0)
}
}


ie something like the following should halve the sensitivity of your mouse:

Code: [Select all] [Download] GeSHi © Codebox Plus

MoveEvent(x, y, mouseId){
x := round(x / 2)
y := round(y / 2)
Global mdw
if (mdw.SelectedMouse == 0 || mdw.SelectedMouse == mouseId){
DllCall("mouse_event",uint,1,int, x ,int, y,uint,0,int,0)
}
}

Hmm, will look into this and let you know.
Can you not disable the wheel code for now? All we really need to know is whether you get smoother movement with this technique...

Grr, there is defo something wrong still with some of the attachments on that thread.
The Multi-Mouse version of MouseDelta.dll is still trying to load version 4..0.0.0 of SharpDX

Gimme a min, will see if I can sort it the hell out.

Fixed it.
To be 100% clear - you want MouseDelta-MultiMouse.zip from this post
Plus SharpDX.zip from the first post.
Plus CLR.ahk

Thanks, no errors anymore but mouse sensitivity ain't changing, tried user and admin modes.

Tested now and it works good. But I can only do 1/2 mouse speed
x := round(x / 2)
y := round(y / 2)
Anything higher like 3,4 causes mouse to move in squares.

Also some toggle/hold button would be good. I guess for this extra script would be needed that would just enable/disable current one?

Nah, we can just add toggle functionality to the script, it's easy.
The likely reason why it does not work properly with higher values is that the majority of the values coming from the mouse will be low values. If dividing by 4, then if the mouse reports a move of 1,2,3 or 4 then it will be converted to 1.
You wanna set the DPI as high as possible, then turn down the sensitivity in the game. That way, it gives it more to work with.

To allow turning it on / off via a toggle, add this code:

Code: [Select all] [Download] GeSHi © Codebox Plus

F1::
toggle := !toggle
return


Then adjust your MouseMove func like so:
