Issues fixed

Enhanced Graphics mode won't enable

Edit the configuration file
  1. Go to the configuration file(s) location.
  2. Open pcconfig.txt.
  3. Change ignorevendorpresets from 0 to 1.

Crash to desktop on startup

Set sound quality to 24 bit, 48000 Hz[5]

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

Crash to desktop in first level

Set FSAA off in effects options menu[6]

Gargoyle crash

The game crashes reliably on some systems when some gargoyles melt an ice wall in the last level of Year 3.
In most cases the problem is caused by incompatibility with the video drivers of the user's computer.
Set DesiredDynamicLightQuality to 0 in configuration file[7]
This makes the lighting look bad. Make sure to return it to the original value after finishing the level.

Run the game at screen refresh rate

Resolutions above 1440x900 are locked to 60 Hz, even if the screen refresh rate is set higher than that.
Set screen refresh rate[4]
  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.

Note: V-sync seems to lock game to 60hz even with Special K. Nvidia Control Panel, or Rivatuner didn't help either. Used 2560x1440 @ 240hz monitor to test this.
