The HyperX Pulsefire Haste 2 and Haste 2 Pro use the latest and greatest sensor, the same as all of their competitors, capable of up to 26,000 dots per inch. That means far greater sensitivity (or resolution) than the previous model. While that might be this mouse’s most important upgrade in this generation, the main difference between the Haste 2 and the Haste 2 Pro is the polling rate.
To match the higher dpi, this is the first HyperX mouse with a 4,000-hertz polling rate. This is how many times a mouse reports its position to a computer—the higher the number, the more responsive cursor movement. Most mice have a 1,000-Hz polling rate, but esports mice can go up to 8,000 Hz.
There’s been a lot of talk about whether such a spec is even useful. Plenty of tests show that the difference between 4,000 and 2,000 Hz is visually imperceptible, even on monitors with extremely high…
