The concept of "Taxa de Polling" or polling rate is primarily associated with devices like mice and keyboards, where it refers to the frequency at which the device reports its status to the computer. In the context of Windows environments, understanding and optimizing the polling rate can be crucial for improving the responsiveness and performance of input devices, especially in gaming or precision-required tasks.

Understanding Polling Rate

Polling rate is measured in Hertz (Hz), indicating how many times per second the device sends data to the computer. For example, a 1000 Hz polling rate means the device reports its status 1000 times per second. Higher polling rates can result in more responsive inputs, but they can also increase CPU usage.

Checking and Changing Polling Rate on Windows

1. Checking Polling Rate:

   • While Windows itself doesn't provide a built-in tool to check the polling rate of a mouse or keyboard, third-party software like Mouse Rate Checker can be used. These tools typically display the current polling rate by tracking the frequency of input signals.

2. Changing Polling Rate:

   • Some high-end gaming mice come with software that allows users to adjust the polling rate. For example, Logitech's G HUB or Razer Synapse software can be used to change the polling rate settings.

3. Using Device Manager:

   • While Device Manager doesn't directly allow you to change the polling rate, you can ensure that your device drivers are up-to-date, which can indirectly affect performance.
   • Open Device Manager by pressing Win + X and selecting "Device Manager."
   • Locate your mouse under "Mice and other pointing devices."
   • Right-click and select "Update driver" to ensure you have the latest driver.

Practical Example

Suppose you have a gaming mouse that supports different polling rates. Here's how you might adjust it using the manufacturer's software:

• Logitech G HUB:

  1. Open Logitech G HUB.
  2. Select your mouse from the device list.
  3. Navigate to the "Sensitivity" or "Polling Rate" tab.
  4. Choose your desired polling rate (e.g., 125 Hz, 500 Hz, 1000 Hz).

• Razer Synapse:

  1. Open Razer Synapse.
  2. Select your mouse from the dashboard.
  3. Go to the "Performance" tab.
  4. Adjust the polling rate slider to your preferred setting.

Considerations

• CPU Usage: Higher polling rates can lead to increased CPU usage. It's essential to balance responsiveness with system performance.
• Device Capability: Not all devices support high polling rates. Check your device specifications before attempting to change the polling rate.
