Internet Speed Test for Gaming
High Mbps doesn't stop lag. Discover the four metrics that determine online gaming performance — ping, jitter, packet loss and bufferbloat — and use our free tools to diagnose and fix every source of lag in Valorant, Fortnite, Call of Duty, FIFA and more.
Gaming Metrics That Matter More Than Mbps
| Metric | Excellent | Notes | Poor | Impact |
|---|---|---|---|---|
| Ping (latency) | Under 20ms | Excellent — competitive FPS | Over 100ms | Poor — noticeable lag |
| Jitter | Under 2ms | Excellent — rock solid | Over 15ms | Poor — rubber-banding |
| Packet loss | 0% | Excellent — no data lost | Over 1% | Severe — teleporting, disconnects |
| Bufferbloat | A / A+ grade | Under 30ms added under load | D / F grade | Ping spikes 200ms+ under load |
Internet Requirements by Game
| Game | Bandwidth | Ping target | Jitter | Packet loss |
|---|---|---|---|---|
| Valorant / CS2 | 5 Mbps | < 20ms | < 2ms | 0% |
| Fortnite / Warzone | 10 Mbps | < 30ms | < 5ms | 0% |
| Call of Duty | 5 Mbps | < 20ms | < 3ms | 0% |
| League of Legends | 3 Mbps | < 50ms | < 10ms | 0% |
| Streaming + Gaming | 25+ Mbps | < 50ms | < 5ms | 0% |
Run our dedicated ping test, jitter test, packet loss test, and bufferbloat test to diagnose lag beyond raw download speed.
Frequently Asked Questions
What internet speed do I need for gaming?
You need far less bandwidth than most people think. 5–15 Mbps download is enough for any online game. What matters is ping (under 50ms for casual, under 20ms for competitive), jitter (under 5ms), and packet loss (0% ideally, never above 1%).
What is a good ping for gaming?
Under 20ms is excellent for competitive FPS games (Valorant, CS2, CoD). Under 50ms is good for most online games. Under 100ms is acceptable for casual play. Over 100ms will cause noticeable lag in fast-paced games.
Why does my internet lag when gaming even with fast speeds?
Fast download speed does not prevent lag. The most common causes are high ping, jitter, packet loss, and bufferbloat — ping spikes when other devices are downloading or streaming.
What causes bufferbloat and how does it affect gaming?
Bufferbloat occurs when your router fills its queue during heavy traffic, adding 50–500ms of extra latency. If your ping jumps from 15ms to 200ms whenever someone starts Netflix, you have bufferbloat. Enable SQM on your router or run our bufferbloat test.
Is WiFi or Ethernet better for gaming?
Ethernet is always better for gaming. WiFi adds 10–50ms of base latency and introduces jitter. A wired 50 Mbps connection will outperform wireless 500 Mbps in every online game.
Which games need the lowest ping?
Competitive FPS games like Valorant, CS2 and Call of Duty need under 20ms. Battle royales and MOBAs need under 50ms. Sports games under 60ms. MMORPGs and strategy games are more forgiving at under 100ms.
