What the TechTester gaming latency test measures
The TechTester gaming latency test combines four separate measurements that together tell you exactly why your gaming setup feels fast or slow. Here is what each section measures:
System input lag
Time between your click or keypress event and the next visual frame rendered on screen. Measured across 20 rounds in milliseconds. The most direct measure of how responsive your setup feels in game.
Network ping
Round trip time from your browser to major game server regions in milliseconds. Measured via WebSocket requests to Cloudflare, Google, AWS Singapore, US East, and EU West endpoints
Refresh rate confirmation
Your monitor’s actual refresh rate detected via requestAnimationFrame timing. Confirms whether your 144Hz monitor is actually running at 144Hz or defaulting to 60Hz due to a cable or settings issue.
Jitter measurement
Variation in ping over time more important than average ping for smooth gameplay. High jitter causes rubber banding and inconsistent hit registration even when average ping is low.
Min / Max / Average
All three latency statistics shown for both input lag and ping tests. The gap between min and max reveals how consistent your performance is wide gap indicates instability.
Controller polling guide
Reference table showing how your controller’s USB polling rate (125Hz to 1000Hz) directly translates to maximum input lag in milliseconds helps you understand your controller’s hardware limit.
How the input lag test works
The TechTester input lag test measures the time between a mousedown or keydown event firing in JavaScript and the next visual frame being painted to the screen via requestAnimationFrame. This measurement captures your complete system input processing chain browser event handling, JavaScript processing, GPU compositing, and display output all measured in milliseconds.
The test runs 20 rounds automatically. Click the large target area or press any key for each round. Your average, minimum, and maximum input lag appear after all 20 rounds complete, along with a rating based on the table below.
Input lag rating table what your score means
Use this table to understand where your system input lag sits relative to gaming benchmarks:
⚡ | Excellent | Under 8ms | Competitive grade. Equivalent to 1 frame at 120Hz. Top tier gaming setup. Common on wired peripherals with high refresh monitors. |
✅ | Good | 8 16ms | Great for all gaming. 1 frame at 60Hz. Most gamers will not notice any delay at this level. |
🟡 | Average | 16 33ms | Acceptable for casual gaming. Two frames at 60fps. May notice slight delay in fast FPS games. |
🟠 | High | 33 50ms | Noticeable in competitive games. Three frames at 60fps. Enable Game Mode or check display settings. |
🔴 | Poor | Above 50ms | Significant lag something is wrong. Check display post processing, Game Mode setting, and cable type. |
What affects your input lag score
- Display post processing: HDR, motion smoothing, blur reduction, upscaling all add processing time between input and display. The single biggest cause of high input lag on TVs and high end monitors.
- Wired vs wireless peripherals: wireless mouse and keyboard add 1 3ms of wireless transmission latency on average. Bluetooth adds more than 2.4GHz proprietary wireless.
- Monitor refresh rate: a 144Hz monitor shows a new frame every 6.9ms vs 16.6ms for 60Hz directly reducing how long you wait to see the result of your input.
- V Sync: locks frame rate to monitor refresh rate but adds up to one full frame of input lag as a buffer. G Sync and FreeSync reduce this while maintaining tear free output.
- Browser overhead: the TechTester test adds approximately 2 4ms of JavaScript processing overhead compared to native tools. Subtract 2 4ms from your result for a hardware accurate estimate.
How the ping test works
The TechTester ping test measures round trip latency from your browser to major server endpoints using WebSocket connections the same protocol used by most online games for real time communication. Unlike ICMP ping (the standard ping command) which runs at network layer 3, WebSocket ping runs at transport layer 4 and reflects the actual latency your game traffic experiences more accurately.
Server targets and what they represent
Server | Location | Best for |
Cloudflare 1.1.1.1 | Global anycast | Universal baseline lowest possible ping to Cloudflare edge |
Google 8.8.8.8 | Global anycast | General internet latency baseline |
AWS ap southeast 1 | Singapore | Valorant, PUBG, ML:BB most popular Asia Pacific game servers |
AWS us east 1 | US East | Fortnite, Call of Duty, Apex Legends US servers |
AWS eu west 1 | EU West | European game servers relevant for EU and Middle East players |
AWS ap south 1 | India / South Asia | Gaming servers serving South Asia including Pakistan, Bangladesh, India |
Ping rating table what your score means
| Excellent | Under 20ms | Near instant response. Ideal for all competitive games. Common on fibre connections with nearby servers. |
| Good | 20 50ms | Smooth for all gaming including competitive FPS. Most players will not notice any lag at this level. |
| Average | 50 100ms | Fine for casual gaming. May notice slight delay in fast paced competitive games. |
| High | 100 150ms | Noticeable lag in FPS and battle royale games. Hit registration may feel inconsistent. |
| Poor | Above 150ms | Significant lag visible in all online games. Fix your connection before competitive play. |
How the refresh rate test works
The TechTester refresh rate test uses requestAnimationFrame timing to measure how many frames your browser is rendering per second. This directly reflects your monitor’s actual operating refresh rate. A 144Hz monitor that is running correctly will show 144fps in the test. A 144Hz monitor incorrectly configured will show 60fps revealing a hidden performance limitation.
Common reason your monitor runs at 60Hz despite being rated higher
- Wrong cable type: DisplayPort supports 144Hz+ at 1080p and 1440p. HDMI 1.4 (the most common HDMI cable) only supports 144Hz at 1080p not 1440p. If you have a 1440p 144Hz monitor connected via HDMI 1.4 it will default to 60Hz.
- Windows display settings: Right click Desktop then Display Settings then Advanced display settings then confirm the refresh rate matches your monitor’s rated Hz. Windows sometimes resets this after updates.
- GPU driver settings: NVIDIA Control Panel or AMD Radeon Software may have a separate refresh rate setting that overrides Windows. Check both.
- Monitor firmware: some monitors ship with 60Hz as the default and require a manual setting change in the monitor’s OSD (On Screen Display) menu to enable the higher refresh rate.
How controller polling rate affects input lag
Your controller’s USB polling rate determines how often it reports its state to your PC measured in Hz. Higher polling rate means more frequent updates and lower maximum input lag from the controller itself.
Polling rate | Max input lag | Report interval | Common controllers |
125Hz | 8ms | 8ms | Most standard USB gamepads, some Xbox controllers |
250Hz | 4ms | 4ms | Xbox Series X/S via USB |
500Hz | 2ms | 2ms | PS5 DualSense via USB C, some gaming mice |
1000Hz | 1ms | 1ms | High end gaming mice, some keyboard/gamepad hybrids |
Bluetooth | 10 40ms | Varies | All Bluetooth controllers higher and less consistent than USB |
Input lag too high? 7 fixes to reduce it
Fix 1 Enable Game Mode on your TV or monitor (biggest impact for TV users)
Game Mode disables all post processing on your TV or monitor motion smoothing, upscaling, HDR tonemapping, local dimming adjustments reducing input lag by 20 80ms on TVs and 5 15ms on gaming monitors. On most TVs: Settings then Picture then Picture Mode then Game. On Samsung: Settings then General then External Device Manager then Game Mode On. On LG: Settings then All Settings then Picture then Additional Settings then Game Mode.
Fix 2 Disable HDR when not needed
HDR processing adds 10 30ms of input lag on most displays even when the content is SDR. If you are not watching HDR mastered content or playing an HDR optimised game, disable HDR. Windows: Settings then System then Display then HDR then turn off. Also disable in your monitor OSD menu.
Fix 3 Use DisplayPort instead of HDMI for PC monitors
DisplayPort supports higher refresh rates and lower latency than HDMI 1.4 at most resolutions. If your gaming monitor is connected via HDMI and not reaching its rated refresh rate, switching to DisplayPort often both increases Hz and reduces input lag. DisplayPort 1.4 supports 144Hz at 4K, 240Hz at 1440p.
Fix 4 Switch from wireless to wired peripherals
A wired mouse eliminates 1 3ms of wireless transmission latency. A wired controller eliminates 3 10ms compared to Bluetooth. For competitive play, use USB C cable for PS5 DualSense and USB A to USB C for Xbox Series controllers. The TechTester latency test will show a measurable improvement after switching from wireless to wired.
Fix 5 Disable V Sync in game settings
V Sync adds up to one full frame of input lag as a buffer to prevent screen tearing. At 60fps that is 16.6ms of added lag. Disable V Sync in your game settings and use G Sync (NVIDIA) or FreeSync (AMD) instead these provide tear free output with significantly less input lag than V Sync.
Fix 6 Confirm monitor refresh rate in Windows settings
Right click Desktop then Display Settings then Advanced display settings then Display adapter properties then Monitor tab then Screen refresh rate. Confirm it matches your monitor’s rated Hz. Also check your GPU control panel NVIDIA Control Panel then Change resolution and confirm refresh rate. Run the TechTester Refresh Rate Test before and after to confirm the change.
Fix 7 Update GPU drivers and monitor firmware
Outdated GPU drivers can cause frame timing issues that increase measured input lag. Update via GeForce Experience for NVIDIA or AMD Adrenalin for AMD. Some monitors also have firmware updates that improve input lag check your monitor manufacturer support page for firmware downloads.
Ping too high? 6 fixes to reduce network latency
Fix 1 Switch from WiFi to Ethernet (most impactful)
WiFi adds 10 30ms of latency compared to a wired Ethernet connection, plus significantly higher jitter due to wireless interference. A Cat 5e or Cat 6 Ethernet cable from your PC or console to your router eliminates this immediately. Run the TechTester ping test before and after to measure the improvement most users see 15 25ms improvement after switching to Ethernet.
Fix 2 Choose the correct game server region
Every major online game lets you select which server region to connect to. Always select the region geographically closest to you. Pakistani players should select South Asia or Middle East servers where available. Singapore players should select Southeast Asia. Using the TechTester ping test to compare AWS ap south 1 (India/South Asia) vs AWS ap southeast 1 (Singapore) shows you which region is closer to your connection.
Fix 3 Close background downloads and cloud sync
Active downloads from Steam, Windows Update, Google Drive, OneDrive, or Dropbox consume bandwidth and increase latency. Close all background applications that use the internet before gaming. Check Task Manager then Performance then Ethernet or Wi Fi to see current network usage.
Fix 4 Disable VPN during gaming
A VPN routes your traffic through an additional server before reaching the game server almost always increasing ping by 20 80ms. Unless your VPN is specifically designed for gaming and routes to a server closer to the game server than your ISP does, disable it during gaming sessions.
Fix 5 Restart your router
Routers accumulate routing table bloat over time which can increase latency. A simple restart clears this. If your ping is consistently higher than it was when you first set up your connection, restart the router and run the TechTester ping test again. If ping improves after a restart and then gradually increases again over days, your router may need a firmware update or replacement.
Fix 6 Change DNS server
Your ISP’s default DNS server may be slow. Switching to Cloudflare (1.1.1.1) or Google (8.8.8.8) can reduce DNS lookup time by 20 50ms which improves loading times and reduces initial connection latency. Windows: Settings then Network then Ethernet or Wi Fi then DNS server assignment then Manual then enter 1.1.1.1 as primary and 8.8.8.8 as secondary.

FAQ
Input lag is the delay between your physical action (mouse click, key press, controller button) and the visual response appearing on your screen measured in milliseconds at your local machine. Ping is the round trip travel time of data from your device to a game server and back measured in milliseconds over the internet. Both affect gaming responsiveness but from different directions. Low input lag makes your local setup feel responsive. Low ping makes online multiplayer feel responsive.
Under 8ms is competitive grade equivalent to one frame at 120Hz. Under 16ms is good for all gaming. Under 33ms is acceptable for casual gaming. Above 50ms is high and you should enable Game Mode on your display and check your peripheral connection.
Under 20ms is excellent for competitive gaming. Under 50ms is good for all gaming. Under 100ms is acceptable for casual games. Above 150ms causes noticeable lag in all online games.
Enable Game Mode in your TV settings this disables post processing and typically reduces input lag by 20 80ms. Also disable HDR if not needed, use a direct HDMI connection without going through a receiver, and select the correct HDMI port (some TVs only support Game Mode on specific ports).
High ping with fast internet usually means you are connected via WiFi instead of Ethernet (adds 10 30ms), your chosen game server region is geographically far from you, a VPN is active (adds 20 80ms), or background downloads are consuming bandwidth. Switch to Ethernet and select the nearest server region to solve most high ping issues.
Yes. The TechTester refresh rate test works on any monitor connected to a PC running Chrome or Edge. It detects the actual refresh rate your system is currently using which may differ from your monitor’s maximum rated Hz if settings are not configured correctly.
Wired is always better for latency. A wired mouse adds 0ms wireless transmission time vs 1 3ms for 2.4GHz wireless vs 10 40ms for Bluetooth. A wired controller via USB adds 0ms vs 3 10ms for Bluetooth. For competitive gaming always use wired peripherals where possible.
