Rocket League Packet Loss Test
Packet loss is the top cause of Rocket League lag spikes, missed hit-registration and rubber-banding. Rocket League stays smooth under 0.3% loss; 1% is borderline and above 3% it's effectively unplayable. Test your real UDP loss and bufferbloat below, then work through the fixes.
Good ping, jitter & packet loss for Rocket League
| Metric | Optimal | Good | Playable max | No-go |
|---|---|---|---|---|
| Ping | ≤ 30 ms | ≤ 50 ms | ≤ 100 ms | > 150 ms |
| Jitter | ≤ 3 ms | ≤ 10 ms | ≤ 20 ms | > 40 ms |
| Packet loss | 0% | ≤ 0.3% | ≤ 1% | > 3% |
Tiny bandwidth; latency consistency drives smooth interpolation.
How to fix Rocket League packet loss
- 1. Use a wired Ethernet connection
Wi-Fi is the most common source of packet loss and jitter. A cable to the router removes interference and is the single biggest fix for most Rocket League players.
- 2. Enable SQM / QoS on your router
Smart Queue Management (fq_codel / CAKE) crushes bufferbloat — the lag that appears when the line is busy. Many routers expose this as "QoS" or "anti-bufferbloat".
- 3. Pick the nearest server region
Switch Rocket League to the closest region. A nearer datacenter means lower ping and fewer drops; see the region list on the Rocket League ping test.
- 4. Restart the gateway and rule out the line
Power-cycle the modem/router. If loss persists on Ethernet across servers, the problem is upstream — contact your ISP with the measured loss figures.

How FRAGRATE measures this
FRAGRATE measures ping and jitter as a TCP-handshake to a public endpoint in each game region, packet loss via UDP/WebRTC, and bufferbloat as the latency added while your line is saturated. Run it locally for true per-region game-server ping, or use the hosted browser test for ping, loss and bufferbloat.
FAQ
- How much packet loss can Rocket League tolerate?
- Keep packet loss under 0.3%. Between 0.3% and 1% is borderline; above 3% Rocket League is effectively unplayable.
- Why does Rocket League lag when someone else is streaming?
- That's bufferbloat — latency that piles up when your connection is saturated. A fast line can still spike to hundreds of ms under load, so Rocket League stutters mid-fight. FRAGRATE measures latency-under-load to catch it.
- Does jitter matter for Rocket League?
- Yes — keep jitter under 10 ms for Rocket League (Racing). Above 40 ms you get inconsistent hit registration and rubber-banding even when average ping looks fine.
- What is a good ping for Rocket League?
- Aim for under 50 ms; under 30 ms is optimal for Rocket League. Up to 100 ms is the playable ceiling, and above about 150 ms Rocket League feels laggy.
