// The Mac version is hard-coded to use a low video speed value. This defaults
// the video size to half-screen and causes low frame-rate versions of several
// videos to play, even though better versions are included. PC versions read
// config values written by a benchmark in the game's installer. We address
// that by returning a high video speed value of 500 in kGetSierraProfileInt
// and kGetConfig, and so we patch the Mac value to 500 as well.

// Applies to: Mac version only
