Testing Beta in offline. Was flying a P51D around and accidentally collided into an aircraft drone. I received only engine oil damage. When shooting all primary weapons (all 6 .50 cals), the gun muzzle flash does not render as nicely prior to the engine oil damage. Muzzle flashes render in game intermittently. The same applies for tracers- they render intermittently as well when shooting. Intermittent rendering occurs both when in cockpit and in F3 external view.
