You can have lag in networking while your processing or making packets, fixable but not addressed. This is hidden and not added to latency measurements
You can have lag on hops, unfixable not worth addressing unless host/s sucks
You can have lag on wireless access point, thanks for mentioning still have no clue what kernel or features you're running so latency metric is basic.
You're account for some lag but totally ignoring one that can exist at the source. That's not my opinion it's what experts have found.
Thanks for accounting for bluetooth lag.
SQM works so those who have it will not have the problems of those you don't. Consumers need to use SQM to deal with Bandwidth problems becaused it exist their own lans not the isps or the cloud, no streaming tech or isp tech can fix something on your end. You've done this in two different vids now not accounting for the fact SQM literally fixes a problem you mentioned.
Seems you still need a highly debloated connection, decent kernel and hops not to suck on this tech. I actually felt xcloud was better than stadia even though it's beta.
Surprise surprise - 60fps (Killer Instinct) on xCloud lines right up, latency-wise, with 60fps tests Digital Foundry did previously on Stadia and PSNow. All, uncannnily, in the 12Xms range for 60fps fighting games tested on each.
That is to say... the tech is as good as it ever was, but it seems there are no new silver bullets for latency this year.
Saddens me they could be doing a bang up job in some areas but won't.
Latency isn't a silver bullet and its not helped if you use network features built for bandwidth but aren't latency friendly to test or outright just play on streaming service. None of these platforms aim to reduce latency in various areas so the results should laregly be the same. Based on exactly what you mentioned from test there is added 40-80ms added but since testing was limited and hops weren't properly fleshed out narrowing it down would be insanely hard.
I'm being blunt I seriously wonder what a debloated connection on haste would be like vs standard crap consumers are gonna see in test like these.
