Here's a slight revision of the Single Player Quick Mission: "Dogfight - Even" with twice the number of fighters (12 against 12), which I find makes for an endlessly entertaining time (and has helped improve my flying tremendously... though my gunnery leaves a bit to be desired... I'm very new to flight sims). I've included the mission and briefing files below for anyone that would like to fly it (drop them in your: Documents\1C SoftClub\il-2 sturmovik cliffs of dover\missions\Single folder). All AI is set to "Veteran".
The videos are recorded from a track of a mission flown with full realism. My video settings are: Detail Level - High (plus Visual Effects increased to High); AA @ 8x; SSAO, VSync, Grass, Shadows, Roads: On; Antiepilepsy Filter: Off, Resolution: 1920x1080. My hardware is listed in my signature.
The first video is an external view made exclusively with "External Flyby" and the second video is cockpit view from the same track with TrackIR (watch for the close encounters at 2:10 in each video).
