Offline mainly. Online..... well.... I've never managed to get close to a bomber formation!
Mainly because, on the old card, every time I tried flying missions my game would turn into a slideshow, I'd lose the entire squadron and then go face first into a hill.
Been using "Bomber intercept over London" (With autopilot) as a benchmark as Black Death stutters way too much (Mainly when the radio kicks in) so never provides a real measure of performance for me.
