Software

Much like ASUS Armoury Crate, MSI Dragon Center is a UWP-integrated app for all things MSI. And much like Armoury Crate, Dragon Center has a bit of a bad reputation. However, and to anyone's surprise, my experience with Dragon Center wasn't all that bad. The installation went down smoothly, and although the number of processes running in the background and their RAM footprint isn't exactly to my liking, core functionality is pretty decent. Upon opening Dragon Center, one is first greeted by a login screen, but that one can be safely skipped without any resulting restrictions to functionality. On the home screen, three options are laid out at first: True Color, Mystic Light, and Gaming Gear. The first one is entirely unrelated to mouse functionality and merely allows one to apply custom Windows color profiles. Annoyingly, any already applied non-default ICC profiles will be reset on every system start-up and need to be manually re-enabled, which can get quite tedious. Mystic Light concerns lighting settings and is detailed below. Gaming Gear has all the mouse settings. Curiously, when having the latter option open, Dragon Center cannot be minimized directly; rather, just by clicking on its icon on the taskbar.

All settings are presented across two tabs. The first one has button remapping to mouse, macro, and media functions. The second tab includes options for polling rate (125/250/500/1000 Hz), angle snapping (on/off), and lift-off distance (high/low). In addition to that, an option called "Motion Sync" can be enabled, though doing so increases power consumption. Unlike Razer's MotionSync, which is at least partially a hardware-based solution, Motion Sync is entirely firmware-based and aims to tighten SPI timing. For more details, please refer to the appropriate section on the previous page. CPI adjustment is possible for five levels and at a range of 100 to 19,000 CPI, in increments of 100. If a box is checked, up to 20,000 CPI are possible. As the 3370 is capable of increments of 50 CPI up until 10,000 CPI, the restriction to 100 CPI increments is an artificial one. Lastly, profile management is available, too. When applied, all settings are saved to the on-board memory, so the software does not need to be running (or be installed) all the time. On my system, the software had a minimum RAM footprint of 107 MB. However, after having opened certain tabs (such as Mystic Light), this figure may go up by as much as 100 MB for an average of around 200 MB in total. When minimized to the system tray, a RAM footprint of 72 MB is averaged. Upon exiting the application, several processes with a RAM footprint of 67 MB keep running.

For uninstalling Dragon Center, I recommend using the official uninstall tool provided by MSI, which can be found in this not-so-official looking Google Drive. Using this tool, I was able to get rid of all remnants of Dragon Center.

Lighting

The Clutch GM41 Lightweight Wireless has but a single lighting zone, which is the logo at the back. Three pre-defined lighting effects are available: Steady, Rainbow, and Breathing, along with a custom mode. If other MSI devices are present, the lighting may be synchronized with them. Colors, transition speed, and brightness can be further customized. Of course, the lighting can also be disabled altogether.

Color accuracy and vibrancy are excellent throughout. Here's a short demonstration video in which I go through the Rainbow and Breathing lighting effects:

Battery Life

MSI states a maximum battery life of up to 80 hours. Unfortunately, the settings (i.e., RGB lighting and polling rate) that have been used to achieve this number aren't detailed. Dragon Center includes a percentage-based battery life indicator with single-digit granularity. Curiously, when plugged in, a charge level of 95% is erroneously displayed despite the battery no doubt being fully charged. After continually using the GM41 Wireless with a polling rate of 1000 Hz, no RGB lighting, and Motion Sync enabled for 11 hours, the battery life indicator stood at 78%. Assuming a near-linear consumption rate, an expected battery life of roughly 50 hours when using the settings indicated above can be estimated. The battery has a capacity of 300 mAh.

Using the included USB Type-A to Micro-USB charging cable, I've measured charging speed of the GM41 Wireless during the constant current (bulk) stage to be around 0.225 A. Using the charging dock, charging speed typically was around 0.235 A. When connected to the dock, the mouse lights up in a charge level dependent color.
