Subject: AM5 big performance reduction with CSM boot mode and Wi-Fi disabled.

Hello
There is a big performance bug (only affecting games performance) on Linux (not reproducible on Windows) with AM5 boards (at least for my MSI MAG b650 Tomahawk) if these BIOS settings are used:
CSM -> Enabled
Wi-Fi -> Disabled (or set to Bluetooth only)
This does not happen even on Win 7... (I've only tested DX12 games) and does not happen if UEFI mode is chosen. I've tested with many different BIOS versions all showing the same result.
I have tried troubleshooting with MSI with some benchmarks posted (https://forum-en.msi.com/index.php?threads/b650-tomahawk-bios-bug-disabling-wi-fi-massively-reduces-system-performance.396910/) and after a week we realized this only happens on Linux (tested on Arch/Fedora/Ubuntu with 6.8 and 6.9 kernels for the first two).
Please investigate.
Thank you
