More On: Lachesis
Razer announced a new mouse today called the Lachesis and it features a new laser capable of 4000DPI. That's a true 4000DPI folks and not using any software interpolation to achieve this feat. Some other improvements include a much lower lift-off level so the cursor doesn't move as much when you lift the mouse up from the surface. If you don't install the drivers you can switch the DPI which is nice if you take the mouse to be used in other computers. It comes in at $80 joining the Microsoft SideWinder Mouse as another $80 mouse announced recently. The Logitech G9 is the most expensive upcoming mouse of the three though at $100.


Razer Lachesis™ utilizes the Razer 3G Laser Sensor, achieving unheard-of precision, speed and tracking
Leipzig, Germany – August 23, 2007 – Razer™, the leading manufacturer of high-end precision gaming and lifestyle electronics peripherals, announced the Razer Lachesis™ high-precision 3G laser gaming mouse at Games Convention in Leipzig, Germany. Utilizing the brand new Razer 3G Laser Sensor™, the Razer Lachesis is the pinnacle achievement in gaming mice.
Complementing the highly acclaimed Razer 3G Optical Sensor, Razer incorporated similar groundbreaking advancements in sensor technology, creating the Razer 3G Laser Sensor. Combining incredible precision of true 4000DPI and superior tracking speeds of up to 100 Inches Per Second (IPS), compared to other laser mice, the Razer 3G Laser Sensor provides vast improvements in tracking performance over any other laser sensor. The precision laser technology and the unprecedented speed at which the Razer 3G Laser Sensor tracks make it the optimal laser sensor for low and high sensitivity gamers. The Razer 3G Laser Sensor also stops tracking at much lower lift-off levels* than any other laser sensor, preventing tracking errors when the Razer Lachesis is lifted off its tracking surface.

With the introduction of the Razer 3G Laser Sensor, Razer unveils the first mousing sensor to offer true DPI increments modified by hardware, as opposed to other sensors that use smoke and mirrors via software interpolation to estimate the user’s defined DPI. Additionally, since the Razer 3G Laser Sensor is housed within the Razer Lachesis, gamers can also make the most of Razer Synapse™, allowing users to switch DPI on-the-fly, without drivers.

"None of the DPI numbers on our mice are interpolated figures, which other mouse makers’ achieve by enabling tweaking of the software included with their mice. Our DPI specifications are all hardware-based, which essentially means what you see is what you get – true DPI," said Robert “Razerguy” Krakoff, president of Razer. "We’ve also included two more buttons right below the scroll wheel with which gamers can cycle through pre-determined DPI stages. We’ve heard the communities’ requests for true on-the-fly DPI switching and we’ve designed the Razer Lachesis to make it possible."

The Razer Lachesis’ ambidexterity is favorable to gamers who prefer a “claw grip” on their mice for faster and more precisely controlled swipes. The Razer Lachesis features a rubberized non-slip matte finish, with a glowing scroll wheel and pulsating Razer logo.
