Your gaming lag isn't a speed problem. It's routing.
Gaming feels worst at high latency to the game's server, not at low bandwidth. A 50 Mbps connection with 20 ms ping plays better than a 1 Gbps connection with 90 ms ping. Sometimes the issue is the game's regional routing; sometimes it's your ISP's peering choices.
Use PingPlotter or 'traceroute' from your terminal. Find the first hop with latency >30 ms — if it's inside your ISP's network, that's their problem to fix.
Console + ethernet is the single best gaming upgrade most people never make. A $15 cable solves more lag than any router.
Fiber tends to have better baseline latency (5–15 ms vs 15–30 ms on cable) and more direct peering to major game networks. Worth checking — not a guaranteed fix.
