PlanetDoom reports there have been rumours flying around lately that DOOM 3 would not be able to run on computers that have Windows 98 or Windows 98SE as their operating systems. Since we here at planetDOOM dislike rumours in all shapes and sizes, we went straight to the horses mouth so to speak and asked Activision themselves. The reply we got was that it is confirmed and indeed true that DOOM 3 will only run on Windows machines that have windows 2000 or XP and not lower. So there you have it, looks like some peoples upgrading woes just aren't quite over yet.
