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.

GTA Online Ping & Packet Loss Test
Did everyone in your session just "leave" at the exact same time? Cars flying through the air? Stuck on "Transaction Pending"?
Unlike most modern games, GTA Online uses a Peer-to-Peer (P2P) mesh network architecture. Instead of communicating with a single dedicated Rockstar server, your router is actively exchanging ~150-byte UDP packets at roughly 30Hz with up to 29 other players around the world simultaneously. This makes GTA Online arguably the most network-sensitive game on the market. If your connection drops packets or jitters, the P2P handshake fails, and the session instantly isolates you. Standard speed tests check TCP downloads, completely missing the UDP packet instability that causes these session splits. Our tool simulates this 30Hz traffic to expose exactly why you keep lagging out of Heists.
30 Hz
one update every 33.3 ms
What this test sends:
30 packets per second of 350 bytes, matching GTA Online rather than a generic ping.
estimated
Rockstar publishes no rate; sessions are peer-to-peer with Rockstar acting only as broker, so the rate follows the session host.
How to Read the GTA Online Network Graph
Run the 30Hz test above for at least 60 seconds. Here is what your results mean for GTA Online:
Red Lines (Packet Loss)
Red vertical lines mean your connection dropped data entirely. In GTA Online, this triggers the infamous "Session Split." You are driving with your crew, and suddenly the killfeed says everyone left the lobby at once. You didn't get kicked; your router dropped the P2P packets, and the game severed your connection to the other players, dropping you into a solo public lobby.
High Jitter (Stability)
Jitter measures ping fluctuation. If your ping rapidly bounces from 40ms to 150ms, the physics engine completely breaks. Enemy players will teleport down the street, and NPC traffic will spawn directly in front of your car or swerve erratically. Driving in close formation during a mission becomes physically impossible.
High Ping (Latency)
Because the lobby is hosted by a random "Session Host" (another player), high baseline ping means extreme desync. You will shoot a griefer in the head, they will keep running for two full seconds, and then randomly drop dead. It also causes massive delays when buying armor or ammo.
How to Fix GTA Online Session Splits & Desync
If the tool above shows an unstable connection, try these specific fixes.
1. Fix Your NAT Type (Port Forwarding)
The Symptom: You get stuck in the clouds while loading, or constantly end up in solo lobbies.
Because GTA is a P2P game, your router must allow incoming connections from 29 other random routers. A Strict or Moderate NAT Type blocks these handshakes.
Fix Log into your router and enable UPnP (Universal Plug and Play). Alternatively, manually Port Forward UDP Port 6672 to your PC or Console's IP address to force an Open NAT Type.
2. Ditch the Wi-Fi
The Symptom: Randomly dropping out of Heists with the "Connection to the session lost" error.
Wi-Fi naturally drops packets due to interference. When you drop a packet while communicating with a Rockstar cloud server, it retries. When you drop a P2P packet to a session host, they simply boot you to prevent the lobby from lagging.
Fix Run a Cat6 Ethernet cable directly from your router to your setup. This is the single most effective way to stop random session splits.
3. Fix Bufferbloat (Home Congestion)
The Symptom: Cars start floating or teleporting when someone else in the house streams Netflix.
Handling UDP packets from 29 different IP addresses is highly stressful for a standard home router. If someone is downloading a large file, the router queues your game traffic, causing massive P2P desync.
Fix Log into your router settings and enable QoS (Quality of Service). Prioritize your gaming device's traffic over everything else on the network.
4. FiveM Dedicated Server Routing
The Symptom: Normal GTA Online runs fine, but you have terrible ping and packet loss on a specific FiveM Roleplay server.
Unlike standard GTA, FiveM runs on dedicated servers (usually hosted by OVH or AWS). Sometimes your ISP takes a highly congested, inefficient route to that specific server host.
Action Use our server map above to test routing paths. If the route to the FiveM server is broken, use a gaming VPN to force your traffic down a cleaner, more direct backbone network.

Peer to peer: the one game here where your upload matters
GTA Online is the outlier in this catalogue. Rockstar publishes no tick rate - the 30 Hz here is an estimate and is labelled as one - but the more consequential fact is the topology: sessions are largely peer to peer, with Rockstar's services handling matchmaking and persistence rather than simulating the world. Your console or PC is exchanging state directly with up to twenty-nine other households.
That changes what a bad connection means. In a client-server game there is one path to worry about and one machine that decides the truth. Here there are as many paths as there are players, each with its own loss and jitter, and no authority to arbitrate between them. The player warping down the street may have a perfect line while yours drops packets, or the reverse, and neither client can tell you which.
It also makes upload capacity relevant in a way it is not anywhere else on this site. You are not sending one stream to a datacentre; you are sending your state to everyone in the session, so the traffic scales with the lobby. The packets are large by this catalogue's standards - around 350 bytes - and a household whose upstream is already busy will fail in a full lobby while behaving perfectly in an empty one.
The practical consequence is that a clean measurement here is worth more than in most games, because it lets you stop guessing about yourself and start looking at the session. If your line delivers steadily for a minute at the game's own rate, the warping is not yours to fix, and the useful move is a different lobby rather than another evening of port forwarding.
Frequently Asked Questions
Why did everyone leave my GTA session at the exact same time?
They didn't leave; you did. This is known as a Session Split. Because the game is Peer-to-Peer, your router must maintain a constant connection with everyone else in the lobby. If your internet drops packets for even a few seconds, the lobby's network severs your connection to protect the other players from lag, placing you into a solo public lobby.
Why do cars teleport and rubberband in GTA Online?
Rubberbanding is caused by High Jitter and Desync between peers. Since there is no central server dictating where the car is, your client has to guess based on the data it receives from the other player. If their internet (or yours) fluctuates, the car will visually teleport to correct its position.
What is a good ping for GTA Online?
Because the game is Peer-to-Peer, your ping changes depending on who the "Session Host" is. If you live in New York and the host is in Australia, your ping will be 250ms+, and the lobby will feel terrible. Ideally, you want a ping under 80ms to the session host to avoid hit-registration delays.
How do I fix "Saving Failed - Rockstar Cloud Servers Unavailable"?
While gameplay is P2P, your cash and progress are saved to Rockstar's dedicated cloud servers via TCP. If you get this error, either the Rockstar servers are physically down, or your ISP is struggling to resolve the connection to the Rockstar Social Club domain. Try changing your DNS to Cloudflare (1.1.1.1) or Google (8.8.8.8).
