I'm having a similar experience but, for me, my performance is always bad, on the CPU side.
I have a zephyrus G14 2025, with this specs:
It looks like the game is using only 8cores of my 12 cores, and not utilizing the threads, according to the widows task-manager (8core at 90 to 100% usage, and the rest around 20-30%, averaging at 30-40%).
I have tried the cfg file correcting the CPU cores and threads, but the issue remains the same. I have tried multiple graphics configuration, to reduce cpu usage, but it made no difference.
This laptop usually gets really warm when gaming, but with BF6 not even close, yet the game runs around 30 FPS.
My performance overlay is showing always the CPU as red between 35-45, and depending on the graphics settings, the gpu from 120-260.
I have all drivers up to date including the most recent bios and chipset drivers from amd.
Like this the game is unplayable, I'm dying before even the enemy showing on my screen 😓
