Maybe it's my imagination but these sounds have really increased the immersiveness. Be it on the gound, firing my guns in the air, flspa, gear etc etc. I could hear shells 'zipping' by my mannable ack station when a squaddie was battling a panzer/osite and an errant round came close. Or maybe it was just the sounds of the vehicle to vehicle fight lless than 5k off being so much better.
This beta gave hit my fps for about a 20% loss but it would be worth the trade for the new sounds alone. I hope the engine sound becomes directional again. It's the only sound that was the same as the regular version.
