If you enable CSM and disable Wi-Fi using BIOS, gaming performance is massively reduced on AM5 boards... This only happens on Linux. > > I don't know who are the developers involved that is why I emailed stable@vger.kernel.org. stable@vger is not the correct place for generic bug reports like this, sorry. Please try reporting this on the linux wifi mailing list, the developers there should be able to help you out more. good luck! greg k-h
