Logitech this week rolled out a firmware update for its popular G Pro X Superlight 2 mouse that enables a 4kHz response rate. The higher polling rate is designed for high DPI/low gaming sensitivity players who play eSports PC games, which is the target audience of Logitech’s Superlight series of mice.
A higher polling rate on the mouse essentially means that when a frame is rendered, you have an updated and accurate cursor position on the screen. The higher the polling rate, the shorter the time delay between the cursor and its position on the screen.
High polling rates sound great, but they only kick in when your mouse needs to hit that rate. Therefore, a 4KHz polling rate does not mean that your mouse is continuously providing 4,000 updates per second; it means that your mouse is providing 4,000 updates per second. Rather, it simply means that it has the ability to do so.
How all of this translates into perceptible differences is still up for debate, though. YouTuber Optimum, who makes some very in-depth PC gaming tech videos, saw higher poll numbers a few months ago. Optimum found that you need to set the DPI to 1,600 or higher to hit the peak saturation point to force the mouse to update enough to take advantage of 4kHz mode, and even then, there’s no obvious sign of improved smoothness or response.
If you do want to enable 4kHz mode on your G Pro X Superlight 2, a firmware update is now available via the G Hub app. You’ll need to plug your mouse into your computer as both the mouse and wireless receiver will get updated firmware. The new 4kHZ mode eats up a bit more battery life, though, but that’s the price you have to pay to land those crucial head shots faster.
