Although not incredibly famous, Optimizer was one of the best QuakeWorld players in the history of the Netherlands. He reached his peak when he won Duelmania True Masters in 2004, but was criticised by many for his use of rocket jump scripts. These were not illegal back then but frowned upon by many at the time.
Optimizer unfortunately moved on to Quake 4.
