Issues fixed[edit]

Crash to desktop on startup[edit]

Set sound quality to 24 bit, 48000 Hz[3]

See Sound problems (cracking, delays, missing music/effects, etc.)

Crash to desktop in first level[edit]

Set FSAA off in effects options menu[4]

Gargoyle crash[edit]

Set DesiredDynamicLightQuality to 0 in configuration file[5]
This makes the lighting look wierd. Make sure to return it to the original value after finishing the level.

Run the game at screen refresh rate[edit]

Resolutions above 1440x900 are locked to 60 Hz, even if the screen refresh rate is set higher than that.
Set screen refresh rate[2]
  1. Install Special K by following the Special K Unofficial Guide. Manual local installation may work better.
  2. Start the game once and close it to allow the configuration file of Special K to be created.
  3. Open <path-to-game>\d3d9.ini or %USERPROFILE%\Documents\My Mods\SpecialK\Profiles\LEGOHarryPotter.exe\SpecialK.ini depending on the installation method you used.
  4. Change RefreshRate=-1 to RefreshRate=0.
  5. Change EnableTextureMods=true to EnableTextureMods=false.
