GTX is a graphic mod developed for id software's Quake 4 that enhance the game experience with new graphic effects never seen before in the base game.
This is an old "trailer" which I made in 2006, it shows parts of the cinematics and a little part in first person gameplay with the new graphic by GTX . I never finished it but it's a good way to show you how GTX inprove the game aspect, in motion.
The background music is "When I sleep" by Neurological ( moddb.com/members/131887/neurological ).
