Question Windows task manager and Nvidia app

[punisher_09]

Hello! I recently installed Stalker 2 and I found that the task manager reports about 80-90% CPU usage, while Nvidia app reports 60-80% CPU usage, during gaming on high preset. Which of them are true ?

My PC:
Ryzen 5 7600 (non x)
32GB DDR5 6000MHz (2x16GB)
RTX4060 12GB
M.2 PCI-e 4.0 1TB SSD
650W PSU (Super Flower)
