@plotinus_enjoyer @rlier23 @WashedOutGundamPilot In the way Fw190s were used, challenging B17s and their Fighter Escorts at over 20,000ft over Germany, high altitude does matter.

But the Fw190D is a product of the Emergency Fighter Program, it was never intended to fight at that high altitude, its an offensive fighter, not a defensive one like the Bf110 or Bf109.
