Yeah my computer would crap itself if it tried to run that. I'd try it though if I had a gaming rig. I've watched some gameplay videos of it, looks neat, although I cant remember if it was that or No Mans Sky but the dog-fighting flight mechanics looked terrible in one of them.
I played Microsoft Allegiance many many years ago, so I would expect a space plane to fly like a space plane (direction the craft is facing and direction you are moving are disconnected to some extent.)
