High CPU single Core Usage?

[BlackUlrich]

I notice how my game performs ok but not as it should and after watching my task manager XD there's a single core running at 100% all the time

my PC specs are:
CPU: Ryzen 5 2600 stock cooler
RAM: 16 gb DDR4 2666 mhz
GPU: Radeon RX 6600 XT
and the game is inside an SSD NVME Gen3


I know my CPU can bottleneck my GPU in almost all games but it his case it doesnt make sense because it's only one core!
The game is running at 90 fps inside the Aviary home but even if I limit my framerate to 30 the CPU is still at 100%

The proof XD

Probably how the game utilize one single ARM cpu on the mobile is carried over to the PC, and due to it's using a higher bit calculation (256 bit) it's capable of doing its stuffs using only 1 core on the PC. Or simply because the AVX2 section bottlenecked and max out a single core. But as long as the overall performance isn't effected, there's nothing to worry imo. Just keep an eye out for over heating just in case.
