The Mars Score for mice weights sensor + tracking (30%), shape + weight (25%), connectivity + battery (25%) and buttons (20%). Sensor quality plateaued — most flagship mice now share variants of the PixArt PAW3950 or 3395 — so shape and weight are the dominant decisions.

Sensor: DPI is mostly marketing

Any modern flagship sensor (sensor_dpi 26,000–42,000) tracks perfectly in real-world use. The 800–1,600 DPI band is where most pros actually play. Trust IPS rating (max tracking speed) and lift-off distance more than the headline DPI number.

Polling rate: 4 kHz vs 8 kHz

8 kHz polling halves input latency from 1 kHz. The competitive edge is small but measurable, and noticeable on 240 Hz+ monitors. Battery and CPU usage rise with higher polling.

Weight and shape

A 55–65g mouse (weight_g) feels effortless for low-sensitivity FPS players. 70–90g is comfortable for most. Above 100g, fatigue sets in quickly during long sessions. Shape — symmetrical vs ergonomic, hump position, length — matters more than weight for grip-style fit.

Wireless: 2.4 GHz lossless is now table stakes

Logitech G Pro X Superlight 2, Razer Viper V3 Pro, SteelSeries Aerox 5 Wireless, and Pulsar X2V2 all deliver wired-equivalent latency over 2.4 GHz. Bluetooth-only mice are productivity tools, not gaming tools.

Buttons and side scrolling

Optical switches (has_optical_switches) eliminate the double-click drift that kills mechanical-switch mice after 1–2 years. Side scroll and tilt-wheel are productivity essentials but rare on gaming mice.

How vsMars scores mice

Sensor and shape weight highest because shape is irreversible (you cannot adjust it like a keyboard's switches). See the formula on the methodology page and curated picks on best mice.
