In short: Speed test ping is usually under 20 ms when idle to a nearby server your ISP hosts, but game ping measures sustained latency to a possibly distant game server under load. This difference makes speed test ping unreliable for diagnosing high ping in games.
Part of our guide on udp loss detection commands
Idle speed test pings hide real game latency—testing under upload load reveals your true ping problems.
| Speed test ping | <20 ms idle |
|---|---|
| Game ping range | 30-150 ms typical |
| Bufferbloat latency spike | +50 ms under load |
| Upload saturation needed | ≥70% of link |
| Traceroute hops | 5-15 typical |
| Ping test servers | nearby, ISP-hosted |
| Game servers | varied, often distant |
The short version
- Speed test ping measures idle bursts to a nearby server.
- Game ping is a sustained measure to a game server during active play.
- Test loaded ping by saturating upload bandwidth to spot bufferbloat.
- Compare traceroutes to speed test and game servers to find routing issues.
- Use tools or services to optimize connection paths if route issues persist.
Why a speed test's ping and a game's ping are not the same measurement
Speed test ping usually measures a short burst sent while your internet line is idle. It targets a nearby server, often hosted by your ISP, resulting in low latency figures under 20 milliseconds.
Game ping measures the round-trip time to a game server while gameplay actively sends and receives data, often to servers far away geographically or routed differently. These pings are sustained and fluctuate more.
The speed test server and the game server are rarely the same. The test server is near to minimize ISP transit delays, while game servers might be hundreds or thousands of miles away, causing higher ping.
Also, speed test ping reflects idle line conditions, while gaming ping happens while your connection is busy carrying game data, voice chat, or uploads, which affects latency. It helps to understand pc lag test for packet loss before going further.
- Speed test ping: burst, idle line, nearby server
- Game ping: sustained, busy line, distant server
- Different routes: ISP-hosted vs game network
- Latency affected by upload and download load
How to run a speed test while the connection is loaded, and what delta between idle and loaded ping points at bufferbloat
To reveal if your high game ping stems from bufferbloat, saturate your upload bandwidth while running a ping test. Upload at least 70% of your maximum upload speed to create congestion.
Compare the ping times in two tests: first with no other traffic, second while the upload is maxed out. A large increase in ping, often 50 ms or more, signals bufferbloat: the router or modem queues packets, causing lag.
If ping remains stable under load, bufferbloat is less likely. Your high ping may come from routing issues or game server distance instead. If that sounds like your situation, read up on troubleshooting gaming performance issues next.
Several free tools let you run these tests. Use them to measure your connection under load before applying fixes.
- Find your max upload speed using a standard speed test.
- Start saturating the upload bandwidth by uploading a large file or using an upload speed tool.
- Run continuous ping tests to a stable server during upload saturation.
- Observe the difference between idle ping and loaded ping.
How to find the game server's IP and compare a traceroute to it against a traceroute to the speed test server
Locate the game server’s IP address by checking the game’s network logs, using command-line tools, or third-party websites dedicated to your game.
Run a traceroute to the game server IP: this shows the path packets take through the internet and the latency to each hop. The other half of this decision is steps to fix modem packet loss.
Run a traceroute to your speed test server IP (shown in the speed test result). Compare the two paths for differences in hop counts, delays, and routing.
Long or unstable routes to the game server, many hops, or high latency at specific hops explain high game ping.
This comparison helps you distinguish if the problem lies in ISP routing, game server location, or external networks. It helps to understand separating driver bugs from network issues before going further.
- Find the game server IP or hostname via game network info or tools.
- Open a command prompt or terminal.
- Run 'tracert <game-server-IP>' (Windows) or 'traceroute <game-server-IP>' (macOS/Linux).
- Run the traceroute command again using the speed test server IP.
- Compare the number of hops and latency values.
What to do first when the loaded ping spikes versus when it stays flat and the game ping is still high
If your ping spikes under upload saturation, you have bufferbloat. Fix it by implementing upload shaping or using Smart Queue Management (SQM) on your router. This smooths the packet flow and lowers latency under load.
If loaded ping stays flat but game ping remains high, the issue likely lies in network routing or server location. Your ISP’s routing policies or distant game servers increase latency, which you can’t fix by shaping alone.
In routing issues, try changing game server regions if possible, or use services like GearUP to optimize your route to the game server. GearUP reroutes your game traffic via faster, more stable paths without changing your download or upload speeds. We go through udp packet loss measurement techniques step by step elsewhere on the site.
Identify the problem type by measuring ping under load first, then apply the corresponding fix.
- Loaded ping spikes: bufferbloat, fix with upload shaping or SQM.
- Loaded ping flat, game ping high: routing or server distance problem.
- Try different game servers or optimize route with software like GearUP.
Why a fast download speed does not rule out a saturated uplink during voice chat or game updates
Download speed tests don’t measure upload saturation. Your uplink can be congested during game updates, voice chat, or cloud backups, causing delay spikes even if downloads look fast.
Upload congestion delays outgoing packets, increasing your game ping and causing lag or rubber-banding. This explains why speed test ping looks fine but game ping is high.
Check upload bandwidth use during gaming by monitoring your router or task manager. If it’s near 100%, expect ping spikes.
Prioritize game traffic or reduce background upload tasks to keep uplink clear for gaming.
- Fast download ≠ free uplink
- Uploads block game packets causing high ping
- Monitor upload usage during play
- Limit background uploads and voice chat bandwidth
Which single figure to record before and after a fix so the change is checkable
Record your loaded ping to your game server, ideally as an average over several minutes or game sessions.
Use continuous ping tests or the game’s in-built network stats to find this value.
Compare that number before and after applying fixes like upload shaping or route optimization. A reduction of 20 ms or more is typically noticeable in gameplay.
Also track packet loss and jitter if your tools allow it, as these impact game stability too.
Keeping a log of these stats helps you confirm improvements or spot regressions.
- Start continuous ping to game server during gameplay or simulated load.
- Note average ping, packet loss, and jitter.
- Apply your chosen fix (upload shaping, route optimization).
- Repeat test under similar conditions.
- Compare before/after results to verify impact.
Questions people still ask
Why is my game ping higher than my speed test ping even with a fast connection?
Speed test ping measures an idle burst to a nearby server, while game ping is sustained to often distant servers under load. Network congestion or routing can increase game ping despite fast speed tests.
What is bufferbloat and how does it affect my game ping?
Bufferbloat occurs when your router or modem queues packets too long under upload congestion, causing large latency spikes visible as high ping during heavy upload use.
How do I find my game server's IP address?
Check your game’s network logs, use command-line tools, or third-party websites dedicated to your game to find the server IP your client is connecting to.
Can changing game servers reduce my ping?
Yes. Different servers are located in different regions with varying routes and distances. Choosing a closer or better-routed server can lower your ping.
Will a faster download speed improve my ping?
No. Download speed does not affect ping directly. Upload saturation and routing matter more for latency in online games.
Is using a game booster like GearUP safe and effective?
GearUP optimizes game traffic routing without altering gameplay or frame rates. It is safe, does not cause bans, and can reduce ping and connection instability by selecting better internet paths.
