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.

Dota 2 Ping & Packet Loss Test
Pressing BKB but nothing happens? Missing crucial last hits? Hero stutter-stepping?
Dota 2 servers operate at 30 Ticks Per Second (30Hz). Every single millisecond matters when you are trying to manta-dodge a spell or perfectly time a Black Hole. Your client sends small, ~150-byte updates to Valve's servers 30 times a second. Because MOBAs rely on rapid, hyper-precise mouse clicks, standard internet speed tests completely fail to diagnose Dota 2 lag. They only test raw bandwidth. Our tool simulates exact 30Hz UDP traffic to expose the hidden packet loss and jitter that is ruining your MMR.
30 Hz
one update every 33.3 ms
What this test sends:
30 packets per second of 150 bytes, matching Dota 2 rather than a generic ping.
verified
Source 2 runs Dota 2 at 30 ticks per second; visible in net_graph.
How to Read the Dota 2 Network Graph
Run the 30Hz test above for at least 60 seconds. Here is what your results mean for Dota 2:
Red Lines (Packet Loss)
Red vertical lines mean your connection dropped data entirely. In Dota 2, this causes "ignored inputs." You press your ultimate, hear the audio cue, but the spell never casts. It also causes massive freezes right as chaotic 5v5 teamfights break out.
High Jitter (Stability)
Jitter is ping fluctuation. If your ping rapidly bounces from 30ms to 90ms, your muscle memory is rendered useless. Your hero will start "moonwalking" or sliding, and your attack animation canceling will constantly fail because the server delay keeps changing.
High Ping (Latency)
Dota 2 features an intentional mechanic called "Turn Rates." When you combine slow hero turn rates with high baseline ping, your hero feels like a truck driving in mud. Dodging fast projectiles like Pudge hooks or Mirana arrows becomes mathematically impossible.
How to Fix Dota 2 Lag & Stuttering
If the tool above shows an unstable connection, try these specific fixes.
1. Adjust In-Game Network Quality
The Symptom: Constant micro-stutters and high packet loss registering in the top right corner.
Dota 2 has a built-in engine setting that dictates how aggressively your client requests data from the server. Incorrect settings here will choke your connection.
Fix Open Dota 2 Settings > Advanced Options > Network. Ensure "Network Quality" is set to I have a High-End Network. Only select Low-End if you are forced to play on a terribly weak Wi-Fi connection.
2. Ditch the Wi-Fi
The Symptom: Your hero randomly stops responding to move commands for a split second.
Wi-Fi naturally drops packets due to interference. The Source 2 engine demands a perfectly steady stream of data to track your rapid APM (Actions Per Minute).
Fix Plug a Cat6 Ethernet cable directly from your router to your PC. This is the single most effective way to eliminate packet loss in Dota 2.
3. Fix Bufferbloat (Home Congestion)
The Symptom: Massive ping spikes when someone else in the house opens Netflix or downloads a file.
Your Dota 2 packets are waiting in line behind other network traffic. Your router is bottlenecking the data queue.
Fix Log into your router settings and enable QoS (Quality of Service). Prioritize your gaming PC's traffic so Dota 2 packets completely bypass the queue.
4. Steam Datagram Relay (SDR) Routing
The Symptom: High ping in Dota 2, but perfectly fine ping in Discord and browser speed tests.
Dota 2 uses Valve's SDR network, which bounces your traffic through regional relays to hide your IP. Sometimes, your ISP routes you to a highly inefficient relay node.
Action Use a gaming VPN to force your traffic down a cleaner, more direct backbone path to Valve's datacenters (e.g., US East in Sterling, VA, or EU West in Luxembourg).

The cast request never arrived. Your client showed an optimistic result.

Thirty ticks, forty minutes, and one moment that matters
Source 2 runs Dota 2 at thirty ticks per second, visible to anyone who turns on the net graph, and the packets are small - about 150 bytes. Almost every minute of a match survives a mediocre connection without complaint. Then a fight starts, and the game becomes a sequence of discrete casts whose ordering decides the next twenty minutes.
That concentration is what makes the game deceptive to diagnose. Nothing in a creep wave will show you that your line drops a packet every few seconds, because the client has time to smooth it over. A blink out of a stun does not have that time: it is one request, at one instant, and if the packet carrying it is lost there is no second chance and no visible explanation. The player sees a hero that did not move and blames the interface.
The 33 ms between ticks also sets a hard floor on precision. Dota's item and ability timings are frequently tighter than a single tick, so the difference between a saved hero and a lost one can be smaller than the interval the server works in - and every millisecond of network latency and jitter is added on top of that floor, not absorbed by it.
This is why a measurement over a full minute is the right instrument for this game rather than an in-client ping number. Ping tells you the cost of the last round trip. What decides fights is whether, across the ninety seconds around them, every one of your requests actually arrived - and that is a loss and jitter question, which the chart above answers directly.
Frequently Asked Questions
Why did my BKB or spell not go off in Dota 2?
This is caused by packet loss. You pressed the hotkey, and your local client initiated the cast animation and sound, but the data packet was dropped by your ISP before it reached Valve's 30Hz server. To the server, you never pressed the button.
How do I show ping and packet loss in Dota 2?
To view your live network stats, go to Settings > Options > Advanced Options > Miscellaneous, and check the box for "Display Network Information." This will place a small overlay in the top right corner of your screen showing your FPS, Ping, and Packet Loss.
What is a good ping for Dota 2?
Because Dota 2 features built-in "turn rates" (heroes take a fraction of a second to physically turn before moving or casting), high ping is extremely punishing. A ping under 50ms is ideal. Anything over 80ms will make last-hitting and dodging skillshots feel incredibly sluggish.
Why am I lagging in Dota 2 with high FPS?
Frame Rate (FPS) is how fast your computer renders graphics, while Ping is how fast your internet talks to the server. If your game is stuttering despite having 144+ FPS, you are experiencing high jitter or packet loss. Run the 30Hz network test above to confirm.
