    Did you try Bazzite ? I believe it ships with a tool to handle this system-wide. I think Steam OS can do that too.

    I found that llms can be useful in troubleshooting.

    Maybe start with comparing hardware sensor stats GPU/CPU temp/frequency/fan etc.

    I think is useful to use a bleeding edge OS since what you are talking about, is a combination of kernel/drivers, user space tools and software.

    Start with something low level maybe clpeak or as part of Phoronix Test Suite. A game is a complex software that touches many parts of a system, especially for laptops where some resources are shared.

    Games and game/steam environment variables is very high software chain. Based on what your are reporting.

    Ie Phoronix: Windows 11 vs. Ubuntu Linux Performance On The AMD Ryzen AI Max PRO 390 "Strix Halo"

    On a geometric mean basis, Ubuntu 25.04 was around 13% faster than the OEM install of Microsoft Windows 11 Pro that shipped on the HP ZBook Ultra G1a laptop.

    Or

    Tom’s hardware: Cyberpunk Phantom Liberty Runs 31% Faster on AMD GPUs in Linux Compared to Windows 11

    You need to look at something low level. There is something unique wrong with laptop + kernel combination. Most search for why a game performance badly will not help you.

    There has been many reported issues of unique issues for laptops that have taken a lot of work to fix like Linux 7.1-rc4 Seeing The Latest Laptop Quirks

    If you are going to use Ilm I recommend using Claude Opus or equivalent. And Run in Claude Code and start with something like “I am running the following hardware:… I am seeing performance regression when running under Linux vs windows. Start with making me scripts to test and document low level performance for both windows and Linux”
