![]() Generally to deal with the discrepancy, manufacturers add smoothing, which is a no-go for gaming, so making an accurate sensor was key. Jitter is the difference between a sensor's estimated movement and the physical movement the mouse itself and it tends to grow at higher DPI settings. The idea behind HERO is to give players the best of the best, an accurate sensor with 1:1 tracking, zero smoothing, and next to no jitter for the entire DPI range, while still holding onto the power efficiency. HERO is Logitech's shot at bringing both ideas together. And that's without the swank RGB lighting. ![]() In contrast, the PWM3366-powered G703 has a tracking resolution of up to 12,000 DPI, but its battery is only rated at 36 hours. The G602 (an M010 sensor mouse) has a tracking resolution of up 2,500 dots per inch (DPI) and is rated for around 250 hours of battery life in performance mode. It was more accurate and efficient than the M0 sensors, but it was a power hog. The PWM3366 became Logitech G's high-end model, going into the G403, G502, G703, G903, and the Pro. Logitech G wanted to push the performance envelope though, eventually creating the PWM3366 sensor with Pixart. Worked most of the time, but occasionally you'd be left with a dead or dyng mouse. ![]() When you're not playing, let your mouse charge. ![]() Manufacturers have gotten around this by providing different options like detachable cables and docks for charging. So, wireless mice that weren't made for gaming would have longer battery life, while wireless gaming mice had battery lives measured in a few days. In the past, there's always been a tradeoff when to comes to optical sensors: the more accurate your sensor, the bigger your power draw. Unfortunately, the power efficiency came at the cost of accuracy and performance. The M010 was designed to be more power efficient than the 9800 sensor, another Avago design which you'll find a large number of gaming mice from other companies. The M010 sensor powered subsequent Logitech gaming mice models, including the G100S, the G402, and the G602. It powered the first Logitech gaming mice quite nicely. The original 30 sensors were based on a sensor design requested by Logitech from Avago, a semiconductor company that many now know as Broadcom. While Logitech (and Logitech G) has released a ton of mice over the years, they've actually used only a few different sensors overall. Logitech principal optical engineer François Morier and gaming portfolio manager Chris Pate walked me through the technology, which was years in the making. While these first devices won't impress gamers who are looking for the latest bells and whistles, they're harbingers of bigger and better things in the future. Lightspeed wireless and the all-new High Efficiency Rated Optical (HERO) sensor are about improving teh technology underpinning Logitech G's products. While both products are quite nice, what's key here is really the technology behind them. "The new Hero sensor in our G603 wireless mouse and the new G613 wireless mechanical keyboard show our commitment to driving wireless performance even further across our product line." Performance a reality," said Logitech G vice president Ujesh Desai. "Lightspeed and Powerplay made the dream of untethered and uncompromised wireless Together both products allow for gaming performance without wires, while also attempting to provide longer battery life. Today, Logitech is kicking things off with the launch of two new products, the Logitech G603 Lightspeed Wireless Gaming Mouse and the Logitech G613 Lightspeed Wireless Mechanical Gaming Keyboard.
