Logitech G9x Closer Look
Gamers usually demand ultra-high performance out of their PCs, their game software, and their input devices. For these reasons, Logitech installed a 5700 DPI laser on their G9x USB gaming mouse. The original Logitech G9 laser mouse enjoyed a full two year product cycle prior to the G9x refresh, which translates into plenty of user feedback (in addition to Logitech's development process, which used gamer-tested prototypes and provided valuable feedback).
One of the most prominent innovations to the G9-series mouse design is interchangeable grips. The G9x Laser Mouse includes two interchangeable grips that let you adjust the comfort and design to your personal needs.
Because I have large hands (go ahead and read into that), the wide load grip works best for me, which has been coated with Logitech's DryGrip technology to wick away sweat during long, intense gaming sessions. To remove the grip shell, press the release button on the rear of the mouse to swap between the included Wide Load and Precision grips. Logitech also offers a Comfort Grip (P/N 993-000218) and Angular Grip (P/N 993-000222) available for direct purchase from the Logitech Replacement Parts website.
At the very heart of the Logitech G9x is the ultra-sensitive laser sensor. This mouse is a lot like a camera: as you move the mouse, the sensor takes successive snapshots of the surface medium and compares the differences among the snapshots to calculate movement and distance. The laser engine in the G9x mouse illuminates the surface medium and enables the "camera" to take its snapshots.
The Logitech G9x has the fortune of being one of the very few laser mouse products to feature an adjustable 200-5700 DPI range. This provides hardcore gamers with greater pointer precision, accuracy, speed, and smoothness. While the laser precision is available on-the-fly without Logitech's SetPoint software, additional features are unlocked with the software installed.
At 5700 DPI, all of that laser sensitivity takes serious bandwidth. The best way to get it from the mouse to the computer with minimal delay is with HiSpeed USB-2.0. Although not quite SuperSpeed USB-3.0, USB-2.0 allows the mouse to have a higher report rate - the number of times per second the mouse sends information to the operating system. More reports per second means smoother, less-jerky cursor movement. Most mice generate 125 reports per second. The G9x mouse can report up to 1000 times per second. With Logitech's SetPoint software, the report rate (polling speed) is also adjustable. (Keep in mind that as the report rate increases, more PC resources are used). Logitech recommends 500 reports per second to conserve system resources, but gamers can set the rate higher using SetPoint.
The Logitech G9x mouse boasts a 5700 DPI maximum resolution (dots per inch) with a programmed SetPoint profile. The higher the number of dots per inch (DPI), the more pixels the pointer on your screen moves for every inch you move your mouse. If you move your mouse one inch with a 1000 DPI sensor, the pointer moves 1000 pixels on the screen. If you move the same one inch with a 2000 DPI sensor, the screen cursor moves 2000 pixels (or twice the distance) moving the pointer across the screen faster.
Why does DPI matter? The higher the DPI, the faster the cursor moves across the screen. A low DPI setting means players need to move their hand farther to get a movement on the screen. With a high DPI setting, players need only move their hand a small distance to get a big screen movement. Also, as screens get larger, a higher DPI is necessary to navigate across the larger screen expanse.
Most gamers belong to the extreme end of the DPI spectrum, but many games benefit from sensitivity switching during play. In the FPS game Battlefield: Bad Company 2, a high-DPI mouse sensitivity setting helps control the tank cannon turret. However, in Call of Duty: Modern Warfare 2 a low-DPI sensitive setting may be preferable while sniping (for a slow, precision aim). A low-DPI setting is also preferred for professional applications such as Adobe Photoshop, where a measured precision movement is more desirable.
The MicroGear Precision Scroll Wheel technology offers dual modes for different types of navigation.
Some gamers believe 1600 DPI is too much, while others say there's really no limit. Gamers may never need the extreme 5700 DPI sensitivity from Logitech's G9x mouse, but the available settings are always there whenever the gamer needs them.
