Note - Known issue: If you click within the Sensitivity Randomizer window when open, this can sometimes freeze your mouse until potentially a manual restart. A fix for this issue can be found in 4) Fix for Mouse Freeze Issue.
This tool generates smooth or step-like, randomized sensitivity multiplier curves around a baseline value using Interception and Armadillo in C++. The goal of this tool is to begin to understand the effects of varying mouse sensitivities while aim training.
Ideally, this is something to occasionally train with, but not to have active during actual gameplay. While there's no concrete proof to back this up, we feel smoothly varying sensitivity might increase reactivity and help train fine motor movements in a way that's superior to keeping with a single sensitivity. Thus, the target audience will be people who play aim trainers such as Kovaak's FPS Aim Trainer.

- You may also download the SensitivityRandomizer.zip file directly from my releases.
- Or clone/download the repo from my GitHub.
Once you extract the ZIP file, you must first install Interception. More on what that is in the Details section if you care.
The process is very similar to Kovaak and Povohat's InterAccel, thus some of the installation code/executables are borrowed from them.
- Double click the driver_install.bat file from the extracted ZIP file (It will ask for Admin priviledges).
- Install the Visual C++ Redistributable for Visual Studio 2015 from https://www.microsoft.com/en-us/download/details.aspx?id=48145 if you don't have it.
- Reboot. Yes, you actually need to reboot because of first step, or it won't work.
Once this is done, you should be able to run the tool.
- Run the SensitivityRandomizer.exe file located in your extracted ZIP folder.
- Optional, although highly recommended: Fix Mouse Freeze Issue
Note: The program will begin to generate a complete sensitivity curve. Your mouse may initially freeze for a few seconds while generating this curve. If you want to stop randomizing your sensitivity at any time, either press Control+C or exit the application manually.
This program will look for a settings.ini file that contains several key pieces of information that you can modify. If no settings file is found, it will use default values I've chosen. These components are:
- Type
- Baseline_Sensitivity
- Min_Sensitivity
- Max_Sensitivity
- Spread
- Smoothing
- Timestep (seconds)
- Runtime (minutes)
- Visualize
- Debug
The Type value determines whether you want your generated sensitivities to be step-like or smooth. It takes on two values: 0 (step-like) or 1 (smooth). Setting Type = 1 will result in a sensitivity curve similar to this and behave exactly as previous iterations of the randomizer (v0.1-v0.4):
whereas setting Type = 0 will result in something like this:
The Baseline_Sensitivity value determines determines where you'd like to vary your sensitivity multiplier around. This should almost always be set to 1, as this means you'll vary your sensitivity around a value 1x your current sensitivity value (aka still your current sensitivity).
The Min_Sensitivity and Max_Sensitivity values determine the largest and smallest multipliers that you want your sensitivity to reach. I usually keep Min_Sensitivity = 0.50 (half your default sensitivity), and Max_Sensitivity = 2 (twice your default sensitivity).
Spread determines how fast/wide swings in sensitivities can happen. Counterintuitively, increasing the spread value will not always increase how crazy your generated sensitivity curve is. Because we're attempting to create smooth curves, too much noise (no apparent patterns) will often not produce large variations around the baseline value. We'll be tweaking this in the future, but for now, I keep it at 0.6. If you don't feel this is enough. I'd recommend actually decreasing the value to, say, 0.1 to test.
Smoothing (added in v0.3) determines, well, how smooth you'd like your randomization to be (given that you choose a smooth graph rather than step-like). The smoothing parameter can take on several values:
- 0: No smoothing performed (interesting option to say the least)
- 1: Low amount of smoothing
- 2: Medium amount of smoothing
- 3: High amount of smoothing
- 4: Very high amount of smoothing
- 5: This smooth
I have this value set to 2 by default.
Timestep (added in v0.5) allows you to control how often your sensitivity changes when using the step-like sensitivity randomization option. By default, I have this set to 10, meaning your sensitivity will change once every ten seconds.
Note: If you set Type = 1 (generating a smooth curve), you won't be able to modify the timestep variable. It will be forced at a very small value (0.001) to ensure the generated sensitivity curve is actually smooth. To be able to modify this variable, you'll need to first have Type = 0 set above to specify you no longer want a smooth sensitivity curve.
Runtime (minutes) - Determines how long you want your program to run for before you need to restart. I keep this value at 30 (for 30 minutes).
Visualize allows you to visualize the sensitivity curve the tool generates. By default, this is set to 0 (so no visualization), however setting it to 1 will generate a .txt file called "sens_list.txt". For now, I've included a script called visualize.py that can be run to visualize this output.
Note: You'll need to first have Python and matplotlib installed.
Debug lets you see a live value of your current sensitivity multiplier and a live percentage of time left before needing to restart. By default this is set to 1, however if you're experiencing any performance issues, I'd recommend setting this to 0.
Also, you can press "P" on your keyboard to pause/unpause the program (toggle). So if you find a particular sensitivity you like (or hate for that matter), you can now pause to practice it for a while. With the "Debug" option set to 1, you'll be able to see a PAUSE icon appear.
Until a better solution can be found, I've created a YouTube video that walks you through a fix for this issue (disabling QuickEdit mode in the console). You can also follow the steps below:
- Double-click SensitivityRandomizer.exe
- Right-click the title bar at the top of the window (can be seen in the video)
- Navigate to Defaults
- Uncheck QuickEdit Mode
- Restart the program
If you'd like to know more about how the program actually works, please see this Reddit post where I describe exactly that! If you have any issues running the program, you can:
