Dodek's Improved Sound Evnironment (DISE)'s goal is to create an immersive and enjoyable experience of playing BF2 by enhancing its sound environment and testing it to its limits.
Firing the weapon while crouched will cause dust to rise from the ground. Sniper rifles generate bigger dust cloudsa and they rise even when you're standing. This impacts gameplay a bit. As a sniper you should now plan firing carefully, because the dust cloud will reveal your position easily so take the shot, confirm the kill and quickly change your position.
