    Latency is the name of the game if you’re gaming. Copper will always give you the fastest ping times compared to the fastest wifi you can buy.

        Not even 5 ms. I have a properly set up Wi-Fi at home and you’ll feel no difference in gaming. Wi-Fi only adds like 1-2 ms latency at most.

          Unless you have no choice - a good WiFi will not add noticeable latency.

          Myself I am playing over 5ghz wifi. I would say I don’t feel much difference, but prefer cable any time!

          Is the notebook or desktop wifi NIC and antenna important or only the router? Because when I had a shitty laptop a few years back the latency sucked ass, both at home and at my university (where I hope they had good network components but idk)

        WiFi 5 latency on a decent router (not the shit your ISP gives you for free) is only 0.6ms. Yes, that’s less than 1ms.

          I just tested ping between my weak computers, one of which supports only 100mbit ethernet and are sequentially connected via cheap 2$ dumb switch and ISP-provided router and got 0.187ms average, while ping via same system, but using 802.11ac for one device got 8.16ms with standard deviation of 11.9, maximum of 67ms and minimum of 1.44ms.

          Right. Like even in the shittiest scenario that’s not a major difference. There’s stuff like interference and the speeds are lower, sure, but 1 gigabit is plenty for non enterprise situations

        Your experience varies massively depending on your RF environment. In my suburban neighborhood, I’m getting a stable 3.4ms to my router. The same hardware when I was in a dense urban environment was around 11ms. I’ve never looked at retry counters, but if I had to guess, I’m getting close to zero right now, but was getting considerably higher in a dense area.

      Wireless has a lower minimum latency than wired, that’s why trading houses set up relay towers from Chicago to NYC, in order to achieve the lowest possible latency for their trades between the two markets.

      Wired gives better stability, due to almost zero interference noise. The primary cause of sucky WiFi speeds/stability, is having too many other people’s routers nearby.

        No shit?

        I mean copper runs at 2/3 the speed of light.

        Wireless is pretty much the speed of light.

        I thought they used dedicated fiber for their links.

      WiFi 5 latency is only two times higher than cooper (0.3ms vs 0.6ms). WiFi 6 has the same or even lower latency. WiFi 7 is even better. If latency is your game, copper is a poor choice. Unless you have spare money for an industrial 100Gbps set up. Which you don’t.

        Please speak standards, not marketing language. Replace WiFi and number with 802.11 and letters in the end.

        One packet drop for TCP creates huge latency for application level protocol. And not many games use UDP for their transport.

          Citation Needed

          I have never heard of a latency-sensitive game that doesn’t use UDP for inner loop communication. Sure they use TCP for login and server browser, but the actual communication for gameplay almost always uses UDP.

              Minecraft and Terraria use both TCP and UDP, presumably in the way I described (TCP for initial connection, asset download, etc. and UDP for world state sync). Factorio uses UDP exclusively, and implements reliable transport where needed in software.

                Unless it’s changed in the past year which I doubt, Minecraft exclusively uses TCP for client/server communication. I’ve been modding the game for years and am pretty familiar with the protocol. I think it’s actually one of the few which don’t use UDP to some capacity.

                    Ah okay, didn’t know that does it differently since I’ve never touched it. Makes me wonder why they used UDP for it but didn’t use it in the Java protocol yet.

                Oops, Factorio moved to UDP.

                Can’t find any UDP implementation or even UDP protocol description for Terraria, while there are implementations of Terraria protocol that use TCP and documentation for it. Basically no evidence of UDP and a lot of evidence of TCP for gameplay.

                Minecraft uses only TCP. Sources: wiki.vg, myself, myself and friend of mine and myself again(no link for now, but two minecraft proxy server implementations)
