Graphics feature State WSGF Notes
Widescreen resolution
Only 4:3 aspect ratio is properly supported. See Widescreen resolution.
4K Ultra HD
Field of view (FOV)
Edit the DesiredFOV value in User.ini.
Use -windowed command line argument or edit the StartupFullscreen value under [WinDrv.WindowsClient] in HP.ini.
Borderless fullscreen windowed
See the glossary page for potential workarounds.
Anisotropic filtering (AF)
Use the DirectX11 renderer.
Anti-aliasing (AA)
Use the DirectX11 renderer.
Vertical sync (Vsync)
Edit the UseVSync line in HP.ini. Note that the values here have been reversed: UseVSync=False actually turns Vsync on.
60 FPS and 120+ FPS
No frame rate cap, but very high framerates may break physics and sound in-game. A supposed fix can be found here. (Only changing 0AD7A33B to 00000000 needed). This fix does not work on physics so it's still recommended to cap at 60fps. Game stutters when running above 60fps.

Widescreen resolution[edit]

This fix has title screens for only 3 specific versions.
Use the Unofficial Widescreen Patch[3][4]
  1. Download the unofficial widescreen patch and extract it to <path-to-game>\System\
    • North American version: here.
    • European version: here.
    • Localized Russian version: here.
  2. Go to configuration file(s) location.
  3. Edit HP.ini.
  4. Set the FullscreenViewportX and FullscreenViewportY values to your desired resolution.
  5. Optionally, edit User.ini and set the DesiredFOV value to compensate: 100 for the 16:10 aspect ratio, and 106.26 for 16:9.


Alternatively, you can use the Harry Potter Settings Utility to set the resolution and FOV without having to manually edit the configuration files.
This specific patch will only work for the USA version (Sorcerer's Stone). For European versions you can use this patch and only copy over .u and .dll files (to maintain your language): https://www.moddb.com/games/harry-potter-and-the-sorcerers-stone/addons/hp1-widescreen-fix-ita-edition/#8284137.

Graphical Tweaks via Direct-X 11 renderer[edit]

Unreal Engine DirectX 11 Renderer[edit]

A fork of Kentie's Direct3D 10 renderer that adds more graphical features.
Might cause some bugs and slow rendering in a quest with Filch.
It is compatible with both the Widescreen Patch and Mouse and Strafing Fix.[5]
Runs the game at HD resolution.
Improved lighting.
Adds ambient occlusion, screen space reflections, and higher quality HDR post-processing.
Places a watermark in the bottom right, and overrides the user's clipboard with a link to the developer's PayPal. Follow these instructions to disable the watermark and remove the PayPal link from being inserted into your clipboard.
Installing DirectX 11 renderer
  1. Download the newest version of D3D11 renderer that supports Harry Potter and the Philosopher's Stone (also referred to as Harry Potter 1).
  2. Open downloaded archive.
  3. Copy files from Common directory to <path-to-game>\System.
  4. Copy files from Harry Potter 1 directory to <path-to-game>\System.
  5. From <path-to-game>\System directory delete files SoftDrv.dll, SoftDrv.int, D3DDrv.dll and D3DDrv.int.
  6. Edit <path-to-game>\System\Default.ini with text editor and find a section [Engine.Engine].
  7. Set GameRenderDevice to D3D11Drv.D3D11RenderDevice (i.e. GameRenderDevice=D3D11Drv.D3D11RenderDevice).
  8. Set WindowedRenderDevice to D3D11Drv.D3D11RenderDevice.
  9. Set RenderDevice to D3D11Drv.D3D11RenderDevice.
  10. To disable the watermark and clipboard override, add the following text to the bottom of the file:
  11. Navigate to %USERPROFILE%\Documents\Harry Potter and delete HP.ini.

ESRGAN Upscale Pack[edit]

Includes Widescreen title screens for International releases. Use with Widescreen fix mentioned above.
Installing HP1 ESRGAN Upscale pack
  1. Download the Harry Potter and the Philosopher's Stone ESRGAN Upscale pack


Controller support[edit]

Layout for Xbox gamepads (XInput compatible)

Lack of Deadzone in Right Thumbstick, makes camera spinning. See Camera spinning with Xbox 360 Controller.

Proper mouselook and strafing[edit]

Use the Mouse Fix and Strafing mod
  1. Download the Mouse Fix and Strafing mod and extract it to <path-to-game>\System\
  2. If you have already installed the Unofficial Widescreen Patch, also download the Widescreen Fix and extract it to <path-to-game>\System\

Language reset after installing fanmade patches[edit]

Installing fanmade patches will usually reset the game's language to English in the European release. To change the language, enter the "System" folder on the CD. 3 folders named 0, 1 and 2 can be found there, containing the English (0), French (1) and German (2) language files respectively. In order to manually change the game back to the desired language, copy the desired folder somewhere and manually change all the file endings to .eng from .fre or .ger (i.e. HPcredits.ger renamed to → HPcredits.eng), then copy and paste the folder content into the "System" folder of the game's directory and overwrite everything.

Issues fixed[edit]

The game fails to start[edit]

The game requires a form of DRM, known as SafeDisc implemented in secdrv.sys. Unfortunately, it is a gaping security flaw, and evidently couldn't be fixed without being removed. Microsoft disabled it in Windows 7 and removed it in Windows 10. The following has been tested in Windows 7 to work.
Temporarily start SafeDisc service[citation needed]
  1. Go to the installation folder.
  2. Create a new Windows batch file (extension .bat) and insert the following:
@echo off
sc config secdrv start= demand & sc start secdrv
start System\HP.exe
timeout /NOBREAK /T 1
sc stop secdrv & sc config secdrv start= disabled
@echo on


This effectively reopens the security hole, starts the game, and then patches the vulnerability again after 1 second. You'll likely need to run the script in Administrator mode.
You can experiment with different timings if 1 second turns out to be too short on your system.

Certain transparent effects and textures are not rendered properly[edit]

Edit configuration file
  1. Go to the configuration file(s) location.
  2. Open HP.ini.
  3. Change the UsePrecache= value under [D3DDrv.D3DRenderDevice] to False.
(Alternative) Use console code
  1. Go to configuration file(s) location.
  2. Edit HP.ini.
  3. Set the bDebugMode value to True.
  4. While in-game, press ~ to access the console.
  5. Type flush and press Enter to recache the textures.
(Alternative) Use dgVoodoo 2[citation needed]

Low frame rate on modern systems[edit]

Instructions[citation needed]
  1. Use dgVoodoo 2 or DDrawCompat


If you change resolution from the game settings, dgVoodoo 2 switches to windowed mode, and pressing Alt+ Enter might be required to get back to fullscreen. To avoid this, just force the desired resolution via dgVoodooCpl.exe. Keep in mind that the default game does not support very high resolutions.

Cutscenes are too fast cutting off characters voice lines/Physics bugs/Lumos Glitch/Screen stuttering[edit]

Cap the framerate to 60 FPS or set refresh rate to 60 Hz with Vsync enabled.[6][7]

Brightness slider not working[edit]

Instructions[citation needed]
  1. Use dgVoodoo 2 or DDrawCompat

Bugged sound in Quidditch Match[edit]

Might fix sound issues in other parts of the game aswell.
Instructions[citation needed]
  1. Use DDrawCompat

Camera spinning with Xbox 360 Controller[edit]

  1. Go to the configuration file(s) location.
  2. Open HP.ini.
  3. Locate [WinDrv.WindowsClient] section and change DeadZoneRUV=False to DeadZoneRUV=True.
