Game doesn't use all resources of PC

Hello. Today i tested different render distances and they gave me different FPS
Render distance - average FPS. 
8-360
12-300
16-260
20-220
24-170
28-120
32-90
I have really nice PC (I5-12400f, rtx3070, 32gb ram) and i would like to have higher FPS, but minecraft doesn't even use CPU over 60% and GPU over 50%. I hope this might be fixed. I also added profiling file on 32 chunks, it can give some more information. Thank you!
