滑鼠回報率 1000Hz vs 4000Hz 有差嗎？
近年來電競滑鼠進入了「軍備競賽」，從標準的 1000Hz 一路飆升到 4000Hz 甚至 8000Hz。這些高規格真的能讓您變強嗎？還是只是行銷噱頭？
什麼是回報率 (Polling Rate)？
回報率單位是 Hz，代表滑鼠每秒向電腦回報幾次位置數據。
1000Hz： 每 1ms 回報一次。
4000Hz： 每 0.25ms 回報一次。
高回報率的優點與代價
優點： 理論延遲降低，滑鼠移動軌跡更「綿密」，微小操作更精準。
缺點： 極度消耗 CPU 資源。若您的 CPU 不夠強 (例如舊款 i5)，開啟 4000Hz 反而會導致遊戲掉幀 (FPS Drop)。此外，無線滑鼠的耗電量會大幅增加。
如何測試穩定性？
好的滑鼠不只要快，還要「穩」。使用 GearLab 的測試工具快速移動滑鼠，觀察波形圖：
- 穩定的波形： 點與點之間間隔一致，這代表傳輸品質好。
- 抖動的波形： 如果 1000Hz 測出來在 500Hz~1200Hz 之間劇烈跳動，代表感應器或傳輸不穩，容易造成遊戲中「準心亂飄」。

Mouse Polling Rate: Is 4000Hz Worth It?
In recent years, gaming mice have entered an "arms race," jumping from standard 1000Hz to 4000Hz or even 8000Hz. Do these specs make you a better player? Or is it just marketing?
What is Polling Rate?
Measured in Hz, it indicates how often the mouse reports its position to the PC.
1000Hz: Reports every 1ms.
4000Hz: Reports every 0.25ms.
Pros & Cons of High Polling Rate
Pros: Lower theoretical latency, smoother cursor micro-movements, better precision.
Cons: Extremely high CPU usage. If your CPU isn't powerful enough (e.g., older i5), using 4000Hz can actually cause FPS drops. Also, wireless battery life drains much faster.
How to test stability?
A good mouse isn't just fast; it must be "stable." Use GearLab's tool to move your mouse quickly and watch the waveform:
- Stable Waveform: Consistent gaps between dots indicate good transmission quality.
- Jittery Waveform: If a 1000Hz mouse jumps wildly between 500Hz-1200Hz, the sensor or transmission is unstable, leading to inconsistent aim.
