DOOM & PUBG
In faster paced FPS titles like DOOM, the G903, whether wired or used wirelessly, we have not a single complaint. It tracks well, the DPI range allows us not to have to lift the mouse to spray all of the hellspawn, no matter which direction those evil bastards attack from. When game slows down, such as hiding in a house in PUBG, or in a gold match, or somewhere where the mouse could be allowed to rest, in wireless usage we did notice that this mouse can be too smart for its own good.
We feel like even though the sensor can be tracking movements when used without the cable, the buttons would need to wake before use. Easy to alleviate for those wanting to go wired, but in something like PUBG, you can pull the trigger, and have nothing happen until the button was pressed again. We liked the options to set various profiles, so that we can fine tune the looks and settings for visual queue to select the appropriate onboard file, and get the movement and button arrangement you want most for said title.
Movement is smooth an all pads we tested on, and once tuned to each profile, the movement and accuracy of the sensor got even better. Comfort wise, we have no qualms, and after three months of using this G903, we have no pains, ailments, discomfort, not even a new callous.
Windows and Productivity
A lot of what we mentioned in the gaming section applies to the productivity end as well. For us, using a 4K screen, a higher DPI range is welcomed. Clicking around on various folders and favorites in our browsers went as expected, no overshooting, not jittering, and best of all, not funny stuff going on with the sensor. What we mean by this is that Logitech left the sensor in its natural state, so any movement, no matter how big or how minute, it moves the cursor to your exacting specifications.
Wireless mode shows us that the sleep mode works well. Previously when you worked at desktop level with Logitech mice and walked away, our advice was to turn off the mouse. In the G903, it sleeps well, and the timer is short. So if in something like writing this, and then clicking or scrolling to move to the next section, you may have to jiggle the mouse a bit, and it is possible that the initial click only activates the mouse, but the action is not always read when doing so.
