The three numbers that matter
- Ping (latency) — round-trip time to the game server. Under 50 ms is great.
- Jitter — variation in that ping. Should be under 10 ms.
- Packet loss — under 0.5%. Anything higher and the game retransmits, which feels like rubber-banding.
Fixes ordered by impact
- Go wired. Single biggest win. Wi-Fi adds latency and dramatically more jitter.
- Close uploads. Cloud sync, game updates and OBS uploads saturate your uplink and spike ping into the hundreds.
- Enable QoS on your router and prioritize your gaming device.
- Pick the right server region. Some games default to a region 200 ms away — manually select the nearest.
- Switch DNS to
1.1.1.1to speed up matchmaking and asset lookups.
When the problem is your ISP route
If your ping is high to every server everywhere, your ISP's peering is the issue. A traceroute will show extra hops or one bad hop adding 80+ ms. A reputable VPN with good peering can route around it. For competitive players, a dashboard with recurring latency monitoring will surface the exact times of day the route degrades.
Cloud gaming is different
GeForce Now, Xbox Cloud, and Luna are streaming services with input-loop latency on top of network latency. They tolerate up to about 80 ms; jitter over 15 ms causes visible input lag even when ping looks fine. The Gaming Lag Analyzer has a cloud-gaming profile that measures this combination directly.
