JoyToKey and Raw Accel are both Windows utilities that can change how users interact with games and applications, but they address very different input requirements. JoyToKey focuses on converting game-controller inputs into keyboard and mouse commands, while Raw Accel modifies mouse input through configurable acceleration behavior.
Understanding their differences in functionality, performance, compatibility, system requirements, and practical use cases makes it easier to determine which type of tool fits a particular setup.

What Is JoyToKey?
JoyToKey is a controller-mapping utility designed to make a joystick or gamepad behave like a keyboard and mouse. A controller button can be assigned to an individual keyboard key, a combination such as Alt+F4, or mouse actions such as clicking, scrolling, and cursor movement.
Its profile system allows different configurations to be associated with different applications. This can be useful when the same controller needs different button mappings depending on the game or program being used.
Key JoyToKey Features
- Keyboard key emulation
- Mouse-button and cursor emulation
- Multiple configuration profiles
- Application-specific profile switching
- Button combinations
- Auto Setting Wizard
- Virtual joystick/SHIFT-key functionality
- Multiple assignment sets
- External program execution
- Support for additional keyboard and media commands
JoyToKey Use Cases
JoyToKey is particularly relevant when:
- A game does not provide adequate controller support.
- A user wants keyboard shortcuts accessible from a controller.
- A controller needs to operate desktop applications.
- Different games require different controller layouts.
- Users want mouse functions assigned to controller buttons.
What Is Raw Accel?
Raw Accel official GitHub repository
Raw Accel is a Windows mouse-acceleration driver designed to modify mouse input in the raw input stream. Rather than converting controller buttons into keyboard commands, it changes the relationship between physical mouse movement and resulting cursor movement.
The software provides configurable acceleration behavior, sensitivity controls, gain options, curve styles, and other parameters for users who want detailed control over mouse movement.
Key Raw Accel Features
- Configurable mouse acceleration
- Sensitivity multiplier
- Gain-based configuration
- Multiple acceleration styles
- Horizontal and vertical adjustment
- Anisotropy controls
- Acceleration curves
- Lookup-table configuration
- Input/output velocity graphs
- Raw input processing
- Signed Windows driver
Raw Accel’s guide documents acceleration styles including Linear, Classic, Power, Natural, Jump, and Synchronous, along with more advanced configuration options.
Features and Functionality
Controller Mapping
JoyToKey is specifically built around controller mapping. Users can assign joystick buttons and stick movements to keyboard or mouse actions.
Raw Accel does not provide this type of controller-to-keyboard mapping because its purpose is mouse-input modification.
Mouse Input
Both applications can affect mouse-related behavior, but in different ways.
JoyToKey can emulate mouse cursor movement, clicks, and wheel actions from controller inputs.
Raw Accel processes mouse movement itself and applies mathematical acceleration behavior to the raw input stream.
Profiles and Configuration
JoyToKey provides a straightforward profile-oriented workflow and can associate profiles with target applications.
Raw Accel instead focuses heavily on technical mouse parameters and configurable acceleration curves. Its settings are passed from the GUI to the driver.
Performance and Input Processing
Performance depends heavily on what the software is being used to accomplish.
JoyToKey primarily waits for controller input and generates corresponding keyboard or mouse events. For typical controller-mapping scenarios, its processing requirements are relatively modest.
Raw Accel operates at a lower level because it uses a Windows mouse driver. The driver modifies mouse input before it reaches applications, allowing acceleration calculations to be applied directly to mouse movement.
Raw Accel also provides charts for examining sensitivity, velocity, and gain behavior, giving technically minded users a way to understand how configuration changes affect mouse movement.
Compatibility
JoyToKey Compatibility
JoyToKey is intended for Windows applications and games that can accept keyboard or mouse input. Its usefulness depends partly on whether the target application accepts the emulated input generated by the software.
It can also accommodate older applications through alternative DirectInput-related key-emulation options where compatibility issues occur.
Raw Accel Compatibility
Raw Accel officially targets Windows 10 and Windows 11 on x86-64 systems. Its installation requires the Raw Accel driver as well as supporting runtimes.
The project states that its driver releases are signed and designed with anti-cheat compatibility in mind. However, compatibility with individual anti-cheat systems can never be guaranteed universally.
System Requirements and Installation
JoyToKey
JoyToKey is comparatively simple to deploy because its primary function is software-based controller mapping. Users install the application, connect a controller, create or select a profile, and assign inputs.
Its official site provides the latest version and describes it as shareware that can be downloaded and tried before purchasing a license.
Raw Accel
Raw Accel has more specific system requirements. Its official guide lists:
- Windows 10 or Windows 11
- x86-64 system
- Visual C++ 2019 runtime
- .NET Framework 4.7.2 or newer
- Driver installation
- System restart after installation
Because Raw Accel installs a driver, its setup process is more involved than simply configuring controller mappings.
Pros and Limitations
JoyToKey Pros
- Easy controller-to-keyboard mapping
- Supports mouse emulation
- Multiple profiles
- Application-specific profile switching
- Useful for games without suitable native controller support
- Supports complex button assignments
- Includes virtual joystick/SHIFT functionality
JoyToKey Limitations
- Primarily designed around controller input
- Does not provide specialized mouse-acceleration curves
- Its usefulness depends on how the target application handles emulated input
- Advanced mouse behavior is outside its primary purpose
Raw Accel Pros
- Specialized mouse-acceleration system
- Detailed acceleration controls
- Multiple acceleration styles
- Sensitivity and gain controls
- Visual graphs for analyzing input behavior
- Raw-input processing
- Signed driver releases
- Suitable for users who want precise control over mouse acceleration
Raw Accel Limitations
- Windows-focused
- Requires a compatible x86-64 Windows environment
- Requires driver installation
- Requires additional runtime components
- More technically complex to configure
- Not designed for controller-to-keyboard mapping
JoyToKey vs Raw Accel for Gaming
The two utilities address different gaming scenarios.
JoyToKey is centered on controller customization. It can make a gamepad act like a keyboard or mouse and can maintain separate configurations for different games.
Raw Accel is centered on mouse movement customization. It is more relevant when a player wants to control how mouse movement translates into cursor movement at different physical speeds.
Therefore, the choice between them is primarily determined by the input problem being solved rather than by a simple performance ranking.
Which Types of Users Typically Use Each Tool?
JoyToKey
JoyToKey can be useful for:
- Controller users
- Players of older PC games
- Games with limited controller support
- Users who need custom keyboard mappings
- Users who want controller-based desktop shortcuts
Raw Accel
Raw Accel can be useful for:
- Mouse-focused gamers
- Users experimenting with mouse acceleration
- Players who want configurable acceleration curves
- Users who want to analyze sensitivity and velocity
- Advanced users comfortable with driver-level configuration
Final Comparison
JoyToKey and Raw Accel are fundamentally different utilities despite both being associated with PC input customization. JoyToKey specializes in translating joystick and controller actions into keyboard and mouse commands, with profiles and flexible assignments supporting different applications.
Raw Accel focuses specifically on modifying mouse movement through a Windows driver and provides detailed controls for sensitivity, acceleration curves, gain, and input behavior.
In practical terms, JoyToKey is primarily a controller-input mapping tool, while Raw Accel is primarily a mouse-acceleration customization tool. Their different architectures, features, requirements, and intended workflows make them suitable for different types of input customization rather than direct substitutes for one another.
