Sorry. I poorly expressed myself. While testing ( not in game ) DH is very good ( same as 8 chanel ) but while in game simple 8 channels is much better, i can hear gunshots separately ( footsteps still are very hard to hear ) but with DH its like one big shot, really cant separate them ( footsteps like 8 channels setting ).
I have 7.1 in windows
8 channels, Headphone in Xonar settings ( or DH enabled - tried 7.1 and "simple" DH and various speaker shifts ),
I am noob :) and maybe i set something wrong.
