The Microsoft operating system Windows 7 is separated as a platform of its own because it runs the game at a higher frame rate than any other OS. Windows 7 runs the game at 1 fps higher than other operating systems, about 31.5 vs 30.5, resulting in approximately a 10 minute time save. To keep the speedrun more approachable and technically safer for the future, Windows 7 was separated as its own leaderboard.
