For Inf Source, I'd like to see bullet sounds and explosions travel at the speed of sound, instead of light i.e. you'd hear a bullet impact then depending on the distance of the shooter a few moments later you'd hear the distant sound of their weapon. Can the HL2 sound engine and netcode allow this?
I'd also like to see realistic bullet cracks (read here) instead of the generic whizzes games have when bullets pass near you.
