// GK2 has custom video benchmarking code that needs to be disabled in a local
// procedure called from GK2:init. It sets the game's detailLevel and returns
// a value which is assigned to GK2:speedRating and never used. The maximum
// detailLevel the game recognizes is six so we just set it to that.
