Update 2019-05-20: No Pixels

• Changed ballistics and armor penetration model to account for physical diameter of projectiles, eliminating the "pixel shells" effect
• X-ray mode in AAR can now be toggled with the O key
• Memory cleanup can now be toggled with the "GC" control in the Prefs menu during a mission.  Disabling GC is not recommended, as it un-caps the memory usage of the game, but it can provide temporary relief from stuttering under limited circumstances.  
• Memory cleanup has been mildly improved overall
• Corrected size of APFSDS and HEAT-FS in-flight models
• Fixed an issue where crew hitzones could still be struck in a popped turret
• Fixed an issue where AAR shots that only hit the witness plates on the firing range would not display
• Fixed an issue where AAR traces would be too densely recorded for slow-moving projectiles, which could cause heavy use of time scaling to crashing or freeze the game
• Fixed several issues with AAR data recording to make it more efficient
• Fixed an issue where AI tanks could continue driving after the crew evacuated
• Fixed polarity of IFF panels on Abrams
• Added turret cheek IFF panels to Abrams
• Fixed an issue where FCS could get stuck on the wrong ammo indexing after reloading from an empty breech
• Fixed an issue where animated parts could get their animations interrupted in odd ways
• Fixed an issue where every side section of the Humvees was named "left fender"
• Fixed air resistance of .50 caliber ammo
• Fixed an issue where projectiles could regain their original speed after slowing down from armor penetration
• Fixed an issue where muzzle blast dust glowed in the dark
• Fixed an issue where live rounds appeared extremely cold in thermal optics
• Fixed an issue where tanks could scan in the wrong direction in response to being hit by hostile fire
