Troubleshooting Guide

Having problems with Raw Accel? Fix crashes, settings bugs, mouse issues, and system errors using detailed instructions.

Solve Common Issues and Optimize Your Experience

Whether you’re installing Raw Accel for the first time or fine-tuning advanced settings, you may encounter some issues. This guide provides clear, actionable steps to help you solve the most common problems that users encounter.

Installation Blocked by Windows

Issue: SmartScreen and anti-virus software prevent the Raw Accel installer from starting.

Why it happens: Raw Accel is an unsigned, open-source tool that may cause Windows security alerts.

What to do:

  • When SmartScreen appears, select "More Info" and then "Run Anyway".
  • If antivirus software is preventing the installer from running properly, temporarily disable it.
  • Always right-click the installer and choose "Run as administrator" to grant the necessary permissions.
  • Make sure you're using the most recent version of the installer.

Raw Accel Doesn’t Launch

Issue: The application does not open after installation.

Causes and fixes:

  • Restart your computer to ensure that all services are initialized.
  • Try launching Raw Accel directly from the Start Menu rather than using the shortcut.
  • Navigate to the installation folder and run the.exe file directly.
  • Ensure that your system is not blocking the executable. Right-click the file → Properties → Check “Unblock” (if visible) → Apply.

Mouse Not Detected in Raw Accel

Issue: Raw Accel launches but does not detect your mouse.

Troubleshooting steps:

  • Disconnect and reconnect your mouse to a USB port (avoid using USB hubs).
  • Close any other software that may be controlling your mouse (for example, Logitech G Hub or Razer Synapse).
  • Try a different USB port or mouse to rule out hardware problems.
  • After reconnecting your mouse, restart Raw Accel.

Settings Not Applying or Reverting

Issue: Changes to acceleration curves or settings do not take effect or are reset after restarting.

Fixes:

  • Always click the "Apply" button after making a change to any settings.
  • Run Raw Accel as an administrator to allow configuration files to be written.
  • Check that your antivirus or system policy isn't blocking file changes in the app's folder.
  • Check for profile conflicts; Raw Accel may be switching to a different profile automatically.

Acceleration Feels Inconsistent

Issue: Mouse acceleration is unstable or does not follow the configured curve.

Possible reasons and solutions:

  • Conflicting mouse software may take precedence over Raw Accel. Disable or close them during testing.
  • Ensure that your mouse DPI is fixed and does not change dynamically.
  • In Raw Accel, select the "DPI Normalization" option to align sensitivity with 1000 DPI standards.
  • Adjust curve values gradually; aggressive settings may result in jumpy cursor behavior.

Raw Accel High CPU Usage

Problem: The application uses an unusual amount of system resources.

Solution:

  • Disable the "Last Mouse Move" display. This real-time feedback may be CPU intensive.
  • Avoid leaving the main window open for extended periods of time. The background service utilizes fewer resources.
  • Update to the most recent version, as performance enhancements are frequently included in releases.

Performance Drops in Games

Issue: When Raw Accel is enabled, game responsiveness or FPS decreases.

Recommendations:

  • Make a custom profile for the game and keep acceleration moderate.
  • Set a cap value to avoid acceleration spikes during fast swipes.
  • Close background applications to free up system resources.
  • Check if the game has its own mouse input processing. If so, adjust the Raw Accel settings accordingly.

Profile Switching Not Working

Issue: When launching a game or application, Raw Accel fails to load the correct profile.

Solutions:

  • Ensure that the target application name exactly matches the executable filename (for example, cs2.exe).
  • Check that auto-switching is enabled in your profile settings.
  • Use profiles that are clearly named and do not conflict.
  • To confirm configuration, manually switch between profiles.

LUT and Advanced Features Not Responding

Issue: Look-Up Table (LUT) entries and advanced curve types do not work as expected.

Fixes:

  • Check the format of your LUT entries to ensure they are correctly spaced and ordered.
  • Begin with a simple LUT and then progress to more complex layers. Improper formatting can disrupt curve rendering.
  • If the problem persists, return to a standard acceleration style (such as Linear or Power) and test curve behavior.

Compatibility and Game Restrictions

Issue: In certain games, Raw Accel behaves unexpectedly or generates warnings.

Important notes:

  • Raw Accel modifies input at the system level, which may interfere with anti-cheat systems in some games.
  • Some titles (such as Valorant and Apex Legends) may prevent input manipulation. Before launching a competitive title, use conservative profiles or disable Raw Accel.
  • Before using acceleration tools, always refer to the game's official rules or competitive policies.

Raw Accel Not Saving Settings Between Restarts

Issue: Changes made in Raw Accel appear to apply temporarily but reset after a system reboot or relaunch.

Solutions:

  • Run Raw Accel as an administrator to enable writing to configuration files.
  • Check for permissions issues in the installation folder. Right-click the folder, then select Properties > Security. Make sure your user has full write access.
  • Check that Raw Accel is not being blocked by third-party security software.
  • Unless you are certain that write permissions are allowed, do not install Raw Accel in restricted folders such as Program Files (x86).

Raw Accel Conflicts with Mouse Drivers

Issue: When using branded mouse software, acceleration settings behave unpredictably.

Why does this happen: Manufacturer drivers can override system-level acceleration behavior.

Solutions:

  • Turn off any built-in acceleration in your mouse driver software (for example, "Enhance Pointer Precision" or "Smart Tracking").
  • While testing Raw Accel, you may need to exit the driver software completely.
  • Set your mouse software's DPI to a fixed value and only use Raw Accel for curve control.

Graph Display Not Updating or Appears Broken

Issue: Raw Accel’s graph panel does not render or does not reflect changes to settings.

Troubleshooting steps:

  • To force a redraw, minimize and then reopen the Raw Accel window.
  • Make sure your system supports hardware acceleration and that no GPU overlays (such as NVIDIA ShadowPlay or MSI Afterburner) are interfering with rendering.
  • Update your graphics driver.
  • If the problem persists, disable non-essential visual features such as "Last Mouse Move" or DPI scaling to ensure stability.

Mouse Movement Feels Delayed or Unnatural

Issue: The cursor feels sluggish or “floaty,” particularly during precise movements.

Causes and fixes:

  • Reduce the acceleration value to avoid unexpected sensitivity increases.
  • Set the Input Offset lower for a faster response, or higher for a smoother ramp-up.
  • Check your polling rate—extremely high polling rates (e.g., 1000Hz+) can cause issues with legacy USB ports or unstable power.
  • Consider switching USB ports (preferably USB 3.0 on the back panel) and avoiding hubs and extenders.

Raw Accel Doesn’t Start with Windows

Issue: You want Raw Accel to load automatically when the system boots up, but it does not.

Solutions:

  • Open Raw Accel, navigate to the settings menu, and ensure that the "Start with Windows" option is enabled.
  • If it still does not work, manually add Raw Accel to the startup folder.
    1. Press Win + R, type shell:startup and press Enter.
    2. Create a shortcut to Raw Accel within that folder.
  • Ensure that no system cleaners or optimization tools are blocking startup entries.
