We just got word from Activision that if you have a widescreen monitor you should avoid using the new patch for
Quake IV that was released today. The exact quote is
"Please take down your mirror for the Quake 4 1.1 beta and/or final. There is a problem with the widescreen functionality that may harm a user's monitor. We are working on a re-release and will make it available as soon as possible. Please advise your viewers that may be using the current 1.1 beta and/or final to NOT enable widescreen or disable widescreen if they are currently using it."
As soon as we learn of the new patch we'll let you know.
