Well, the car model itself is indeed low quality, it’s been upscaled from FM3.
The photos here didn’t line up well, especially if I try to make a GIF out of it. One of the worst parts to explain a car model due to time consumptions.
So therefore, the Highest quality Murcielago model goes to - Gran Turismo 7! They have both LP-670 SV and LP-640 in their PS3 titles. Since GT7 released, they only brought the LP-640 back in today’s quality standards.
FM X360 gets the LP-640 as well, but it didn’t return in later Forza titles as they chose the SV more. If they have multiple versions of Huracan and Aventador, why not do the same for Gallardo and Murcielago?
