If you haven’t invested in a sub-woofer and PCI sound card, this is a good excuse to do so. The F9 fly by view is one of my favorite in this sim. Each plane screams by you with its own distinctive engine roar with the full Doppler effect. Shell casings can be seen dropping from beneath out of their exit ports, gun/cannon flashes and muzzle smoke puffs as you squeeze out the rounds.
