The Ultimate Gaming Latency Guide: How to Eliminate Lag and Maximize FPS
Knowledge blog
Summary: Latency is the delay between your input and the server’s response (ping). Lower is better. Stable latency (low jitter) and near-zero packet loss matter as much as the ping number. This guide explains why, and how to fix it—fast.
What is gaming latency (ping)?
Latency is the round-trip time (RTT) for game data between your device and the server, measured in milliseconds (ms). It’s different from bandwidth (capacity). You can have high bandwidth and still feel laggy if latency is high.
Good rule of thumb
- < 20 ms excellent (competitive play)
- 20–50 ms very good
- 50–100 ms acceptable but noticeable
- > 100 ms tough for twitch genres
Jitter and packet loss—why they ruin a “good” ping
Jitter is the variability of delay between packets. A stable 35 ms feels better than a spiky 25–60 ms.
Packet loss is when packets never arrive (rubber-banding, shots not registering). Even 1–2% can feel bad in real-time games.
What physically limits latency?
Distance dominates. Signals in fiber take roughly ~5 μs per km one-way (about 5 ms RTT per 1,000 km), before routing and server processing. That’s why server proximity is so important.
How to measure ping, jitter, and loss (quickly)
• In-game: Use the network/telemetry overlay when available.
• Command line (snapshot tests):
– Windows: ping -n 20 <server> and tracert <server>
– macOS/Linux: ping -c 20 <server> and traceroute <server>
• Continuous view: mtr <server> (or WinMTR) to see per-hop latency and loss over time.
Note: Some networks deprioritize ICMP ping, so trust in-game stats when they exist.
Fixes that actually reduce gaming latency (ranked)
Player-side
- Use Ethernet instead of Wi-Fi if possible.
- If Wi-Fi is required, prefer 5 GHz/6 GHz, reduce obstacles, and avoid congested channels.
- Close background traffic (OS updates, cloud sync, streams).
- Enable QoS/SQM on your router to fight bufferbloat (especially during uploads).
- Pick the nearest server/region inside the game.
- Keep NIC/OS/router firmware up to date.
ISP/Network
- Choose ISPs with good peering to your game regions.
- Use capable routers that can handle your line rate with QoS enabled.
- Avoid daisy-chained extenders; use Ethernet or proper mesh backhaul.
Server-side (for hosts & communities)
- Place servers near players (see the physics above).
- Favor strong per-core CPU performance and ample L3 cache for tick-rate-sensitive engines.
- Use NVMe SSDs (low I/O latency) for fast world streaming, logs, and DBs.
- Keep the OS lean; watch CPU, tick time, RTT, jitter, and loss.
Low-latency hosting checklist (operators/devs)
- Region fit: Deploy where the majority of players are.
- CPU fit: High clocks + large L3; more cores for multi-instance density.
- Storage: NVMe SSDs.
- Network: Well-peered DC, DDoS protection, consistent routing.
- Ops: Monitor RTT, jitter, loss, tick time, saturation; keep kernels/drivers updated.
FAQ
Not directly. Bandwidth is capacity; latency is delay. You need enough capacity to avoid queues, but extra bandwidth alone doesn’t shrink distance or routing time.
