Detecting…
Select your game mode to simulate realistic network traffic. Each game uses a specific tick rate (Hz) and packet size (Bytes) for client-server communication. For example, 'Pro Esports' mode sends 128 packets per second and 200 bytes each packet
Select a server location to test your connection. Our test servers are strategically positioned near major game datacenters to provide accurate results.
PINGPing (Latency) is the time it takes for a data packet to travel from your device to a server and back. A lower ping is better, resulting in a more responsive connection.

JITTERJitter measures the variation in your ping over time. A stable connection has low jitter. High jitter means your ping is inconsistent, which can cause stuttering or lag spikes in online games and video calls.

PACKET LOSSPacket Loss occurs when data "packets" traveling over the network fail to reach their destination. Any amount of packet loss can cause missing audio, video glitches, or disconnections.

Call of Duty: Warzone Ping & Packet Loss Test
Seeing three orange squares? Shoot first, but still die? Parachute lagging?
Warzone is incredibly demanding on your internet. The servers have to track up to 120 players, vehicles, loot, and ballistics across a massive map. It sends very heavy data packets (up to 300 bytes), but only about 20 times a second - Warzone is the one major battle royale that never moved to a 60Hz server tick, because Activision has said the bandwidth would cost three times as much. Call of Duty multiplayer runs up to 60Hz; the battle royale does not. If your network stutters for a fraction of a second, you get the dreaded "Packet Burst" warning. Standard speed tests completely miss these micro-stutters. Our tool simulates heavy 20Hz traffic to catch the exact lag spikes ruining your Gulag fights.
20 Hz
one update every 50.0 ms
What this test sends:
20 packets per second of 300 bytes, matching Call of Duty: Warzone rather than a generic ping.
verified
Warzone servers run at roughly 20 Hz - Call of Duty multiplayer runs up to 60 Hz, the battle royale mode does not.
How to Read the Warzone Network Graph
Run the 20Hz test above for at least 60 seconds. Here is what your results mean for Warzone:
Red Lines (Packet Loss)
Red vertical lines mean your connection dropped data. In Warzone, this causes "super bullets" and unregistered hitmarkers. You empty half a mag into an enemy, hear the armor crack, but the server never gets the data. You die instantly.
High Jitter (Packet Burst)
Jitter is ping fluctuation. If your ping jumps from 30ms to 80ms randomly, Warzone flashes the "Packet Burst" icon (three orange squares). Your game will freeze for a split second right as you aim down sights.
High Ping (Extrapolation)
High ping forces the game to guess where players are going (Extrapolation). This triggers the orange clock icon on your screen. It causes the "Shoot first, die first" syndrome because the enemy sees you earlier than you see them.
How to Fix Warzone Packet Burst & Lag
If the tool above shows an unstable connection, try these specific Call of Duty fixes.
1. Disable On-Demand Texture Streaming
The Symptom: Constant Packet Burst icons when entering new areas or looking at new operator skins.
Warzone tries to download high-quality textures from the internet *while* you are playing. This destroys your bandwidth and causes massive lag spikes.
Fix Open Call of Duty Settings > Graphics > Quality. Find "On-Demand Texture Streaming" and turn it OFF (or set it to Minimal if OFF is removed).
2. Ditch the Wi-Fi
The Symptom: Random micro-stutters during gunfights.
Wi-Fi naturally drops packets due to interference. The Call of Duty engine handles data drops very poorly compared to other games, resulting in severe rubberbanding.
Fix Run a Cat6 Ethernet cable directly to your PC, PlayStation, or Xbox. This is the only real cure for Wi-Fi jitter.
3. Skill-Based Matchmaking (SBMM)
The Symptom: Your ping is normally 20ms, but in Warzone it searches up to 80ms or 100ms.
Call of Duty's matchmaking prioritizes putting you with players of similar skill over putting you in a local server. It will force you into a server states away to match your hidden MMR.
Action There is no setting to turn off SBMM. If it's severe, some players use Geo-Filter routers (like Netduma/DumaOS) to force local connections only.
4. Fix Bufferbloat (Home Congestion)
The Symptom: Ping lines spiking into the red when family is home.
Your game packets are waiting in line behind Netflix streams or background OS updates. Your router is bottlenecking the massive 300-byte packets Warzone sends.
Fix Log into your router and enable QoS (Quality of Service). Prioritize your gaming console or PC traffic.

20 Hz is the whole argument: why Warzone forgives so little
Warzone servers update at roughly twenty times a second, the lowest rate of any large shooter on this site and a deliberate trade for the number of players a match carries. Fifty milliseconds pass between one authoritative picture and the next. Everything you see in between - an enemy rounding a corner, a player sliding off a roof - is your client extrapolating from the last update that reached it.
That extrapolation is what makes a lost packet expensive here. Missing one update costs 50 ms of the world's state, more than three times what it costs in Valorant, and the client cannot pause to wait: it keeps moving the figure along its last known trajectory. When the next packet finally arrives, the correction is large enough to see, and it reads as an enemy teleporting rather than as a network fault. Players blame the netcode, and the netcode is doing what it can with what reached it.
The packets are comparatively large, around 300 bytes, because a battle royale replicates more per update than an arena shooter does. That is still a trivial data rate, but it interacts badly with a saturated upload: a queue that adds 40 ms of delay costs most of a tick, and the game's own packet burst warning can fire without your ping average moving much at all.
This is also why a Warzone player gains more than most from measuring while the line is under load rather than at rest. And if the connection is clean here and the game still stutters, the honest conclusion is that the rate is the limit - which is worth knowing before another evening disappears into changing DNS servers.
Frequently Asked Questions
What does the three orange squares icon mean in Warzone?
The three overlapping orange squares indicate "Packet Burst." It means your game client suddenly received a huge chunk of delayed data from the server all at once. This is usually caused by high Jitter or Wi-Fi interference on your local network. Check the chart above for Jitter spikes.
What is the orange clock icon in Warzone?
The orange clock icon means "Extrapolation." Your ping is so high that the server is forced to guess where you and your enemies are moving. This leads to teleporting players and bullets curving around walls. You need to lower your baseline latency.
Why do I shoot first but die first in Call of Duty?
This is a desync issue caused by ping differences. If your ping is 70ms and the enemy has 20ms, the server registers their bullets 50 milliseconds faster than yours. On your screen, you shot first. On the server, you were already dead. Lowering your ping is the only fix.
Why is my ping higher in Warzone than other games?
Two reasons: First, Call of Duty uses aggressive Skill-Based Matchmaking (SBMM) that will connect you to distant servers to find equally skilled players. Second, Warzone packets are very large, and at 20Hz each one carries more state than a high-tick game's - so a single dropped packet costs you more, not less.
