BF 6 cpu usage 100% ryzen 7 5800x and RTX 5070

You have an older CPU, so it makes sense it's running a little maxed out. Try running on lower graphics settings, perhaps?
I have a 9800X3D and PNY 5080. When I'm playing, they both sit around 60% use.

Here's some CPU troubleshooting tips.

Some of the CPU cores might be maxing out at 100% usage. To check if there are any CPU cores hitting 100% usage, open the Windows Task Manager CPU graph.

• Run the game in windowed mode (alt + enter)
• Open Task Manager (alt + ctrl + del)
• Open the Performance tab, then right-click on the CPU graph and choose "Change graph to > Logical processors".
• Set Task Manager to 'always on top' by clicking option
   
  Now you can play the game and monitor per core CPU usage. If any CPU core hits 100% usage the game will stutter.
   

Also check if the CPU frequency is slowing down in Windows Task Manager. For example, below 3GHz.

Download CPU-Z and verify CPU RAM memory is in dual channel mode.

Make sure XMP/EXPO memory overclocking is enabled in BIOS settings.

I like your eagle avatar!

im already set low btw

haha thanks i also like this avatar, already download cpu-Z, how to enable  XMP/EXPO memory overclocking in BIOS?

btw I made a config like the picture, is it good?

CPU-Z says the RAM is in dual channel mode. That's good!

I would compare with the .cfg file and without. See which one gives higher frame rates.

How many frames per second are you gettings?
