Harry Potter and the Prisoner of Azkaban – PC FPS Fix with Custom Controller Support
This fix adds a stable 60 FPS or 120 FPS cap to Harry Potter and the Prisoner of Azkaban using the game’s internal logic. Running the game uncapped causes major timing issues such as the frozen Imp glitch. This release also includes full custom XInput controller support using Chip’s XInput backend, allowing the entire game to be played with a modern controller.
Features included in this fix
- 60 FPS or 120 FPS launchers
- Prevents high-FPS game bugs (including the frozen Imp glitch)
- Full XInput controller support
- Analogue walking and running
- Fully editable control layout through d3d8.ini
- Standalone launchers; no game files are overwritten
How to use (FPS launchers)
Download the fix and extract the folder then go into HP3-FPS-Cap-Game-Launchers.
Choose either HP3-60FPSLauncher.exe or HP3-120FPSLauncher.exe.
Extract the launcher you want into the game’s system folder next to hppoa.exe.
Run the chosen launcher one time.
If the launcher does not start the game, try running it as administrator.
You can then continue to play the game normally using hppoa.exe.
How to use (Custom controller support)
Download the fix and extract the folder then go into HP3-Custom-Controller.
The controller layout is provided by default as in the images above.
Extract d3d8.dll and d3d8.ini into the game’s install folder, usually:
C:\Program Files (x86)\EA Games\Harry Potter and the Prisoner of Azkaban(TM)\system
The game must load through hppoa.exe in this folder.
Walking and running are analogue using the left stick.
All controls can be customized inside d3d8.ini, with clear explanations in the file.
If you experience double input
Go to:
C:\Users\YOUR_NAME\Documents\Harry Potter and the Prisoner of Azkaban
Open hppoa.ini
Set UseJoystick=True to UseJoystick=False
This disables the game’s built-in controller detection to prevent conflicts with XInput.
