Here at the tail end of the Game Developers Conference in San Francisco, gaming accessory powerhouse Logitech is launching a new mouse in the family of G-series products, the G303 Daedalus Apex. That’s a hell of a name for a mouse to be sure, but the feature set and technology included in this $60 gadget will get some attention from PC gamers and enthusiasts.

Based on the same basic housing and design as the Logitech G302, the G303 is an incredibly lightweight mouse targeted at the gaming community that has such a metric in mind. It includes the same button and spring combinations as the G302, a metal-spring tensioning system, as well as RGB lighting that can be customized with 16.8 million colors.

The most important new feature of the G303 though is its upgraded optical sensor. Using the Logitech PMW3366, the same sensor found in the Logitech G502, the G303 brings the same level of accuracy and performance to a lighter weight mouse. The technical feature set of the sensor are impressive:

  Logitech PMW3366 Sensor
Sensor Features Exclusive Clock Tuning Technology
Delta Zero™ Technology
Zero Smoothing
Zero Filtering
No Pixel Rounding
No Pixel Doubling
Sensor Surface Tuning
Tracking Resolution: 200 – 12,000 dpi
Max. acceleration: >40G
Max. speed: >300 ips
Responsiveness USB data format: 16 bits/axis
USB report rate: 1000 Hz (1ms)
Microprocessor: 32-bit ARM

Obviously a 12,000 DPI rate is a bit much for any user to really utilize but the capability of the PMW3366 allows it as an option. Other features directly target the gaming market, like Zero Smoothing that guarantees no lag or latency in mousing due to comparisons of sensor data. Clock Tuning is based on Logitech’s inclusion of a crystal that maintains speed and acceleration characteristics despite traditional degradation of these traits over time or due to part-to-part variance. Each G303 should feel the same and the performance should be identical from day one through year one.

The G303, along with the G502, that utilizes the PMW3366 sensor, can take advantage of Surface Tuning – the ability for the mouse to tune itself to the texture of the plane it’s being used on. By enabling the feature in Logitech’s software then moving the mouse in a series of figure eights, surface-to-surface experiences should be similar.

G303 Daedalus Apex also has advanced Surface Tuning technology as an integral feature of the PMW3366 sensor. Surface Tuning is a technology used to tune mouse parameters to match a surface. Most gaming mice that have “surface tuning” optimize only for lift-off distance by adjusting LED intensity, which can sacrifice maximum speed. G303 Daedalus Apex optimizes the sensor dynamic range to match the properties of your mouse surface for maximum high-speed performance in addition to lower lift-off distance.

The same build quality and software infrastructure that sit behind the G302 and the rest of the Logitech G gaming mice follow to the G303 Daedalus Apex. Buttons rated at 20 million clicks, metal spring tensioning system, intuitive software to manage the DPI presets and 6 programmable buttons along with easy customization of the RGB lighting system create a total package that is beyond the $59 MSRP. As a direct comparison, the G302 will continue to sell for $49 using the older sensor controller while the G502 runs at $69 leaving plenty (maybe too many) options for gamers.

Logitech sent me at G303 and G502 for testing late last week and I am planning a short story on my experiences. It will be hard to beat the G402 for sheer speed (remember our video review trying to break the accelerometer) but a direct comparison is forthcoming.

Logitech G Announces Arx Control (+SDK) for iOS and Android

The Arx platform is created by Logitech G to deliver "second screen experience" to PC gamers through their iOS or Android devices. Arx Control will have the ability to adjust your mouse DPI, rebind macros, and see the status of their gaming machine. Logitech did not specify the system information that would be given by app, but it does not matter in the end because they are releasing an SDK for it.

The Arx Control SDK, along with the LED Illumination SDK and the G-Key Macro SDK, will allow game and application developers to interact with "Logitech G" devices and the Arx Control app. This could range from providing ammo meters and timers, to offers of in-app purchases. That last point is clearly aimed more at developers than customers because that sounds really scary to me. Then again, it can be done correctly -- such as Team Fortress 2, in my opinion.

What could be cool is if a friend, watching you play, could contribute to the gameplay in some way. Then again, if a developer wanted to put that much effort, they could probably create a mobile web app. This is probably more useful for small things, like the aforementioned ammo and health status indicators, that would otherwise not be worth a developer's effort, without Logitech's platform.

The Logitech G Arx Control SDK is available now for free and the Arx Control App will be available soon on the iOS App Store and Google Play.

Optical + Accelerometer

When I met with Logitech while setting up for our Hardware Workshop at Quakecon this year, they wanted to show me a new mouse they were coming out with. Of course I was interested, but to be honest, mice have seemingly gone to a point where I could very rarely tell them apart in terms of performance. Logitech promised me this would be different. The catch? The G402 Hyperion Fury includes not just an optical sensor but an accelerometer and gyro combo.

Pretty much all mice today use optical sensors to generate data. The sensors are, basically, taking hundreds or thousands of photos of the surface of your desk or mouse and compare them to each other to measure how far and how fast you have moved your mouse. Your PC then takes that data from the mouse at a USB polling rate, up to 1000 Hz with this mouse, and translates it into mouse movement on your desktop and in games.

There is an issue though - at very high speeds of mouse movement, the optical sensor can fail. It essentially loses track of where it is on the surface and can no longer provide accurate data back to the system. At this point, depending on the design of the mouse and driver, the mouse may just stop sending data all together or just attempt to "guess" for a short period of time. Clearly that's not ideal and means that gamers (or any user for that matter) is getting inaccurate measurements. Boo.

To be quite honest though, that doesn't happen with modern mice at your standard speeds, or even standard "fast" gaming motions. According to Logitech, the optical sensor will start to lose tracking somewhere in the 150-180 IPS, or inches per second. That's quite a lot. More precisely that is 3.8 meters per second or 8.5 miles per hour.
