OFF thats why i realy dont consider Superfetch essencial, i think it is good maybe in a enterprise environmento, or a office, where you work with "not so heavy" Aplications, where you only want is to work fast, have your program open faster, and so on.. But when you game, are you realy concern in who many seconds (yeah! seconds, nor minutes or hours ) the game opens? Of course not, and look at this: you have superfetch, and your game opens 5 seconds faster than without it, and then it takes more 30 seconds to load the level.. so you loose 25seconds, and dont win anything... so its your choice..
