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.

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.

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.

Let’s see… Terraria, Factorio, Minecraft.

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.

The original PC Java client uses TCP; every other client, including the C++ PC version, uses UDP.
