Many users experience issues with DS4Windows and Radeon software interfering with exclusive fullscreen mode in games. This often manifests as screen tearing, stuttering, or the game simply refusing to run in fullscreen. This guide will walk you through troubleshooting this common problem and getting your games running smoothly with your DualShock 4 controller.
Understanding the Conflict
The core issue stems from a conflict between DS4Windows' virtual controller driver and AMD's Radeon Software's fullscreen optimizations. Both attempt to manage graphical output and input, leading to a clash that disrupts the smooth running of games. Radeon's "Exclusive Fullscreen" mode, while offering performance benefits, is particularly sensitive to these conflicts.
Troubleshooting Steps
Here's a step-by-step approach to resolving the incompatibility between DS4Windows and Radeon's exclusive fullscreen mode:
1. Update Drivers
Crucially, ensure both your graphics drivers (Radeon Software) and DS4Windows are up-to-date. Outdated drivers are a frequent source of conflicts and glitches.
- Radeon Software: Check the AMD website for the latest drivers compatible with your graphics card model. Properly uninstall your old drivers before installing the new ones for optimal results.
- DS4Windows: Check the DS4Windows GitHub page for the newest version.
2. Adjust Radeon Settings
Within the Radeon Software settings, explore these options:
- Disable Enhanced Sync: This feature can sometimes interfere with other applications attempting to control the display refresh rate. Disabling it might resolve the issue.
- Disable FreeSync/Radeon Anti-Lag: While generally beneficial, these features can occasionally conflict with DS4Windows. Try disabling them temporarily to see if it resolves the problem.
- Check for Overlays: Disable any Radeon overlays (like the performance overlay) during gameplay. These can sometimes cause conflicts with other applications.
3. DS4Windows Configuration
Within DS4Windows, there aren't many settings directly related to fullscreen modes. However, these adjustments might help:
- Restart DS4Windows: A simple restart can sometimes clear any lingering conflicts.
- Hide DS4 Controller: While not ideal, temporarily hiding the DS4 controller in the DS4Windows application may solve the problem.
- Reinstall DS4Windows: As a last resort, try uninstalling and reinstalling DS4Windows to ensure a clean installation.
4. Game-Specific Settings
Some games have their own fullscreen options. Experiment with the in-game settings:
- Borderless Windowed Mode: This mode often provides a compromise, offering many benefits of fullscreen without the same level of driver interaction.
- Fullscreen Optimizations: Check for any graphics-related settings in the game that might be interfering with the Radeon or DS4Windows software.
5. Check for Conflicting Software
Other applications running in the background, particularly those that interact with your graphics card or controller, could be contributing to the issue. Try closing unnecessary background processes before launching the game.
6. System Restore (Last Resort)
If all else fails, consider performing a System Restore to a point before the issue began. This is a last resort as it will revert other system changes.
Conclusion
By systematically working through these steps, you should be able to identify the root cause of the conflict between DS4Windows and Radeon's exclusive fullscreen mode. Remember to test your game after each step to pinpoint the solution. If the problem persists, providing specific details about your hardware and software versions will help in further troubleshooting.
