Yeah, that would be much more real with this mod!!!
The only thing that should be improved in this mod is the glowing. It is more intense in reality and a little different colour. Should be glaring at one little point without making it it too big. But maybe it is not recognizable in youtube video...
If tracers flying in your own direction, they should fly slowers first at beginning and the more approaching the faster they should be animated. Finally at the "end" the bullets are that fast that you still can´t believe it. As a true tracer fetishist, i would be so happy if dev team would take this serious :D
Arma III could benefit so much with a fixed real looking tracer model. I do really hope they change this till final version. Then this would be the finest kind of sim, the world has ever seen...
