Razer Mouse Polling Rate Test

Change your Razer mouse polling rate in Synapse 4, then compare the movement update rate received by your browser. Use this page before and after changing 1000Hz, 4000Hz, or 8000Hz settings, with the same measurement method as our main mouse test.

Measurement notes

Change Razer Polling Rate in Synapse 4

Razer's current support instructions use Synapse 4. The available presets depend on the mouse, firmware, and whether you are using a compatible HyperPolling dongle.

1. Open Synapse 4

Dashboard

Select your Razer mouse from the dashboard. If it does not appear, reconnect the device and check firmware or dongle pairing first.

2. Go to Performance

Mouse -> Performance

Razer lists the polling rate controls under the Performance tab. Some models show more presets than others.

3. Pick a preset

125Hz to 8000Hz

Choose the target rate, then return to this page and retest. The setting label and the measured result are not always the same.

How to Verify a Razer Mouse After Changing Hz

Test before and after changing Synapse

Run one baseline test before changing anything. Write down the average rate, lowest 500 ms rate, and stability when available. Then change the polling rate in Synapse 4 and run the same movement pattern again. This makes the result easier to trust because you are comparing your own setup against itself.

Use movement that can saturate higher polling rates

High polling rates need enough movement to produce enough updates. For 4000Hz or 8000Hz, slow cursor movement often under-reports because there are not enough pointer changes to sample. Use fast circles or figure-eights for 6 to 10 seconds, and compare the average and lowest 500 ms rate. Keep moving until you stop the test; pauses remain part of the average.

Read the result like a stability check

Stability describes the consistency of sample counts in complete 500 ms windows. Movement speed, browser delivery, and system load can all affect it. A low score alone does not diagnose a mouse fault or predict gaming performance. Peak is a single-interval maximum and may be unavailable when timestamps are too coarse.

Why browser results can differ from desktop tools

This page counts browser-visible movement samples, including coalesced samples when available. It cannot verify every USB poll. Desktop tools can observe a different input layer, so results may differ, especially at higher rates. Use repeated tests under the same conditions for comparisons.

Razer Polling Rate Reference

Use this table to interpret what each preset means and when a lower rate may be the better setting.

Preset Interval Good for Watch for
125Hz 8 ms Battery saving, office use, basic troubleshooting. Noticeable input delay for competitive games.
500Hz 2 ms Casual play and stable wireless behavior. Less responsive than 1000Hz on high refresh displays.
1000Hz 1 ms The safest competitive baseline for most Razer mice and games. Usually the best fallback when higher rates stutter.
2000Hz 0.5 ms A moderate step up for 240Hz+ displays when stable. Higher CPU and USB load than 1000Hz.
4000Hz 0.25 ms High-refresh competitive play on compatible hardware. Game engine stutter, wireless interference, browser delivery variation.
8000Hz 0.125 ms Top-end wired or compatible HyperPolling setups. USB path quality, CPU load, dongle placement, browser under-reporting.

If Razer 4000Hz or 8000Hz Does Not Show

Use this checklist before assuming the mouse is defective.

Check model support

Not every Razer mouse exposes every polling rate preset. Some 4K and 8K modes require specific mice, firmware, or a HyperPolling dongle.

Use a direct USB path

For wired mice, plug into a native motherboard USB port. For wireless, keep the dongle close to the mouse and avoid hubs.

Reduce 2.4GHz noise

Razer recommends keeping the HyperPolling dongle within 30 cm and away from active USB 3 hubs that can generate 2.4GHz interference.

Update firmware

Firmware updates can affect available presets and dongle compatibility. Update the mouse and dongle before troubleshooting deeper.

Retest with faster movement

Slow movement can under-report high rates. Move continuously for 6 to 10 seconds and compare average plus lowest 500 ms rate when available.

Try a lower stable rate

If a game stutters at 4000Hz or 8000Hz, use 1000Hz or 2000Hz. Stable input often matters more than the highest preset.

Razer Mouse Polling Rate FAQ

Short answers for common Razer Synapse and HyperPolling questions.

How do I change polling rate on a Razer mouse?

Open Razer Synapse 4, select your mouse from the dashboard, open the Performance tab, and choose the polling rate preset. The available options vary by model.

Why does Synapse show 8000Hz but an online test shows less?

Browser tests count the movement samples they receive, and high rates can be limited by movement speed, browser processing, CPU load, USB stability, or wireless conditions. A low reading alone does not establish a device fault. Compare with a suitable native tool if you need lower-level input measurements.

Do all Razer mice support 4000Hz or 8000Hz?

No. Razer's available presets depend on the specific mouse, firmware, connection mode, and whether a compatible HyperPolling dongle is used.

Should I use 8000Hz for every game?

Not necessarily. 8000Hz can reduce input intervals on compatible hardware, but it also raises CPU and USB load. If a game stutters, compare its behavior at 1000Hz or 2000Hz under the same conditions. For a deeper breakdown, compare 1000Hz vs 4000Hz vs 8000Hz polling rate.

Does Synapse need to stay open after changing polling rate?

Razer devices often store core performance settings on the device, but behavior can vary by model and profile. If your result changes after closing Synapse or waking from sleep, reopen Synapse and retest.
