No, not even close
It is about as close to the real sound as the P-51's Merlin in IL-2 is to a real Merlin. lol
Its cause on current video D.VIII had an Gnome engine (160 hp, same as on N28), so if youd like to compare the sound - compare it with N28 sound.
PS to wf2: so hows your impressions about D.VIII FM?
