I used some programs like "Game Booster"(dunno if that's the name) while playing Graal over the client, and it was kind of helpful. But nowadays, if I spar over Firefox mainly, my GraalClient and my RemoteControl are open all the time. Of course this increases my delay a bit, but I'm faster aswell and people started to think I'm using trainers. So, as Ash said, there's a way to boost your speed on a PC all the time given.
