Battlefield 1 on my Lenovo Legion Go portable handheld gaming PC

What optimization steps did i perform on my Lenovo Legio Go handheld PC (after being banned by EA)?
-I updated the BIOS to version 26
-I set 4 GB VRAM in the BIOS (in the beta BIOS you can choose between 6 and 8 GB of VRAM)
-I updated the GPU driver and AMD Software: Adrenalin Edition (date 2023-11-28)

Here is my screenshot with DirectX Diagnostic Tool:

screen resolution: 1920x1200 60Hz and graphics quality: medium
Lenovo Legion Go handheld PC can stable 60 FPS.

my new experiment:
I bought a USB docking station that has an HDMI port.
And I connected the Lenovo Legion Go handheld PC to my Samsung TV with this dock.

I tried to optimize the Lenovo Legion Go handheld console a little more for the BF1 game.
I updated the BIOS (v28, release date 2023-12-07).
I increased the VRAM first to 6 GB and then 8 Gb.
But it was not possible to get 60 FPS with "1920 x 1200, 60 Hz, High graphics quality" settings.

My photo shows the the physical size difference between Lenovo Legion Go (2023) and PlayStation Vita (2012):

I updated the BIOS of my Lenovo Legion Go console to the latest, version 29.
After that I set automatic VRAM allocation in this new BIOS (new feature).
According to dxdiag.exe 420 MB VRAM is reserved in this mode.
And the BF1 game crashed after my first try.

I tested the new AMD gpu driver for Lenovo Legion Go with the Battlefield 1 game (shocking result for me). With the previous AMD graphic driver I had ~60 fps with high settings (1200p, 60 Hz, 6 GB VRAM). Now I have 30-40 fps with the driver released yesterday (v31.0.24028.1001).
