The Final Fantasy XIV Endwalker Official Benchmark uses actual maps and playable characters to assign a score to your PC and rate its performance including scene loading times.
The benchmark gives an overall load time as well as loading times by scene.
Corsair's MP600 Core Mini doesn't do that well enough in the Final Fantasy XIV Endwalker Official Benchmark. It doesn't get close to topping any of the individual scene load times and overall it ends up in the bottom four in the results chart.
