This MOD is a (much needed) graphical overhaul for Quake 1.5 Public Beta 1: a set of texture-replacements taken from other MODs and here and there on the Internet and added together to Quake 1.5, so that it also looks acceptable - or even very good! - for modern standards. Making these texture-sets work in Quake 1.5 has required a certain amount of effort, due to the complexity of the internal structure of Quake 1.5 itself. Therefore I decided to create a new MOD, name it "Quake 1.5 HD", so that everyone can easily enjoy the new weapons and the new gore system in combination with high resolution textures. The game is not heavy, at all. However, it requires a decent PC (not suitable for more than 20 years old hardware). Its weight is due to ray tracing: it is not path traced but it has RT light sources, so that most scenes appear much nicer than on the original game.
