Wait, wasn't it just one year ago that Logitech released the G500s, the rebirth of its venerated G5 line of gaming mice? Hold on for just a second while I check my review. Yep, that was just last March. But here we are, with another new high-end gaming mouse, the G502. And this year, Logitech's given it a fancy moniker: the Proteus Core. I'm not sure if that's meant to evoke a certain StarCraft faction in gamers' minds, or simply a take on the SAT-friendly word 'protean', meaning versatile or adaptable. The latter's likely the case, given the G502's ability to be calibrated for different mousing surfaces (glass and mirrors notwithstanding). Regardless, Logitech's new flagship is an aggressive product, an $80 mouse that not only succeeds last year's G500s, but revamps the design of Logitech's gaming mouse line. That curvy G5 design that I was so hot on last year has once again been retired (at least temporarily).
I've been testing the G502 for about a week, in first-person shooters, real-time strategy games, and lots of desktop imaging work. I'm not a MOBA player, so my perspective may not reflect those playing the dominant PC gaming game type today. And as I've said before, a gaming mouse is an accessory that most people rarely change--they find the one that works for them and stick with it. If you like the Razer DeathAdder, Mad Catz R.A.T., or even Logitech's own previous G-series, mice, there's really not a lot of reason to spend another $80 on a new gaming mouse unless your current one breaks. Gaming mice technology has really reached a point where every new generation of product offers fewer new benefits; product engineers really feel like they're reaching when they push the boundaries of sensor DPI or add more configurable buttons. And the G502 has plenty of those new back-of-box features, for sure. Let's run through them and evaluate whether they truly add any benefit to your gaming experience.
Arguably the most important component in a gaming mouse is its sensor, and the G502's optical (IR) sensor was apparently designed from the ground up to introduce two notable features. The first is DPI (dots per inch, or technically counts per inch) sensitivity that ranges from 200 to 12000. You read that correctly: this mouse is sensitive to past 10,000 DPI, which I believe is a first for a gaming mouse. (Consider that the G5, circa 2005, topped out at 2000 DPI). At that maximum setting, the tiniest flick of the wrist will send the cursor all the way across a 1080p panel; it's meant for gamers who want to make extremely large movements quickly, or desktop users running multiple monitors spanning many thousands of pixels wide. Of course, high DPI doesn't denote accuracy, just sensitivity. A mouse set to 10,000 DPI isn't useful if it isn't accurate at that "resolution"--the trick is testing the mouse's accuracy at the sensitivities that you find most useful.
