Logitech has released a firmware update that unlocks a bonkers 25,600 DPI resolution on select mice from its lineup. The company is leveraging its HERO in-house developed sensor to demonstrate its capabilities, achieving a "sub-micron level sensitivity" as a testament to its hardware prowess. Granted, Logitech knows users will be hard-pressed to actually gain anything from this DPI resolution compared to, say, the 16,000 DPI that is more common amongst high-end mouse solutions. More than anything, this serves as a sort of "achievement unlocked" for the company.

The 25,600 DPI do mean that the mouse doesn't need any external corrections on its way to 98% tracking accuracy though - no mouse smoothing or acceleration is required. Users who have chosen to partner with Logitech and acquired a G903 Hero, G502 Lightspeed, Pro Wireless, G703 Hero, G604, G502 Hero, G403 Hero, or a Pro mouse all can have this latest firmware installed, which will increase the selectable DPI settings in Logitech's G Hub. Just use the hub to download and install the new firmware revision and you should be all set to go.

Logitech has announced an upgraded, improved model of their legendary G502 mouse, in a Lightspeed edition. Ignoring the quantum implications of having a mouse that moves at lightspeed on your palm, the new, updated G502 features Logitech's Latest, in-house Hero 16K sensor: up to 16,000 DPI processed by a 32-bit ARM Cortex-M-based SoC. Logitech says their wireless performance in their proprietary Lightspeed technology is comparable to that of a wired solution, offering 1 ms lag through special, purpose-designed features of the mouse.

Magnetic charging technology available in Logitech's mouse mats mean you'll never be out of juice, with the G502's battery supporting 800 charge cycles before degradation starts to set in. 11 programmable buttons, adjustable weight (starting at 114g up to 130g) and quality of life additions to the mouse's structure, such as rubberized compounds and the G502 Lightspeed's RGB lighting bring this particular rodent up to a $149 pricing.
