Activision sends along a beta patch for Quake 4, updating Raven's first person shooter to version 1.0.5. For this update id Software and Raven worked together with Intel to improve performance of the game on systems equipped with Hyper-Threading Technology, multiple processors or dual core CPUs.

Players who have a system with one of these configurations will notice performance gains in QUAKE 4 of anywhere from 25% - 87% depending on processor type.
