Gaming mice use either optical or laser sensors to track movement. Today most gaming mice use optical sensors. Here is how they differ.
Last updated: October 30, 2026.
Optical sensors
Optical sensors use an LED and a small camera to track the surface. Modern optical sensors are accurate and widely used in gaming mice, including the PixArt sensors named in many listings.
Laser sensors
Laser sensors use a laser and can track on more surfaces, including glass, but can be less consistent on cloth pads. They were common on older gaming mice.
Which is better for gaming?
Most gamers choose optical sensors for their consistency on cloth and hard pads. Some newer optical sensors also track on glass, according to makers.
Sensor quality matters more than type
Look for tracking accuracy and low smoothing rather than the maximum DPI figure. See our gaming mouse buying guide.
Your mouse pad
The surface affects tracking. See XL mouse pads and hard mouse pads.
Frequently Asked Questions
Are optical mice better than laser?
For gaming, most players prefer optical for consistency.
Can a gaming mouse work on glass?
Some newer sensors list glass tracking. Check the product page.
Does DPI depend on the sensor?
The sensor sets the maximum DPI, but you use a modest value. See best mouse DPI for gaming.
Bottom Line
Choose a good optical sensor and a suitable pad.
