Ethernet Advanced Settings Best Practice for MSFS 2020

Understanding that there is not a single right answer, there are numerous “Gaming focused” ethernet advanced settings advice out there for tuning the ethernet adapter for gaming. Can someone point me to a credible source specific to MSFS 2020 regarding tuning my ethernet adapter settings to optimize for MSFS 2020? My PC (Windows 11) is high end as is my cable internet service; however, I am intrigued by the suggestions that the default adapter/driver configuration can be tuned to bring tangible improvement with flight simming.

Is this true in anyone’s experience? If so, please point me.

The solution in my case was to set windows global autotuninglevel to normal:

netsh int tcp set global autotuninglevel=normal

How this setting got set to disabled I’ll never know.
