MSFS 2020 isn't utlilizing full gpu -cpu(mainly low wattage of gpu)

There isn’t a problem with cooling ,because in another application(like cyberpunk) I got 100% utilization with 150 watt power of gpu. Also, please read well then answer. In the msfs 2020, Gpu got %100 utilization ,but It works with low wattage ,therefore it is obvious that it is a bug which only occurs in msfs 2020
