IMHO that's the matter of accuracy. That's an object created for the game and does have nothing in common with the real plane. Just it pretends a fighter plane. I would say that's the mix of parts taken from different planes. The fuselage is from Yak fighter machine while the wings look like taken form Il-2. The fuselage doesn't have the air intake for the oil radiator under the nose so it may be considered to be from Yak-3, Yak-9UT or P. However the fuselage is too bulgy and too short at the front part. Also there is lack of the small air intakes at the wing roots. The blue lightnings on the fuselage sides may indicate the Yak-3 and exclude the Yak-9 series. But as I said I wouldn't discern any real aircraft in the game model.
