Also be aware that your FOV also impacts the accuracy in determining the exact direction the approaching gv is coming from. The existing game sounds are fairly generic, with my advanced Game Sounds settings, with my engine off, I can hear a gv 3200 yds out. With my engine running, I can hear a gv 800 to 900 yds out. Gv sounds and the GV sector dar are key tools in locating your enemy. Chalenges sound pac does not give me the same range data as the generic sounds do.
Puma44 is right, we lost an outstanding gv-er when DR7 passed on, but we still have some outstanding players here. Tyfoo is one of them, then there's Charger5, Rush, Mano, Dcat, BTBrando, Damphyno, TWCmav1, 27th, 49jagpaw, Slaxer, well I could go on and on. I am sure any of these would be more than happy to help you learn more.
