I removed variables from my post. I did that because there are so many factors at play here it would be impossible to list all the caveats and guess at someone’s WIFI deployment. Optimal WIFI 5 and WIFI 6 setups would have no noticeable difference for game streaming. WIFI 6 will handle connections better when some of those variables are introduced. It also depends on the source of streaming as many programs deliver the stream differently.

So, in a roundabout way, WIFI 6 is going to be better at handling connections which can improve the streaming experience… depending on setup. Is it going to be some magical improvement over WIFI 5 if you have it set up properly, no.
