Software

For the XM1r, Endgame Gear cooked up an entirely new software. Some functions have been added, but being Electron-based, resource usage has gone up a bit as well. Furthermore, the software is still in the beta stage and suffers from several bugs. In my case, the Ripple Control setting proved non-functional, and I had to run the software with administrator privileges to get the lift-off distance setting somewhat reliably working. Dragging the window around barely works in my case, too.

All settings are presented on a single page, with several extendable menus on the right side. Button remapping to mouse, media, and CPI functions is possible for all but the left and right main buttons, which cannot be reversed, either. CPI can be adjusted for up to four color-coded levels, in increments of 50 across 50 to 10,000 CPI and increments of 100 from 10,100 to 19,000 CPI. Unfortunately, values cannot be entered manually; instead, a rather short slider is used, which can prove finicky. Further options include LOD adjustment (1 or 2 mm), angle snapping (on/off), and ripple control, the latter of which wasn't working for me. If enabled, ripple control lowers jitter at higher CPI steps, but at the cost of increased motion delay. Additionally, a setting called "input selection" is present. As of now, only a single setting (raw input) can be selected, which is enabled by default. Endgame Gear plans to add an alternative mode which processes input differently: SPI data and USB polls will be synchronized to each other, but at the cost of up to an entire polling period (i.e., 1 ms at 1000 Hz) of added latency. This firmware solution is different from such a hardware solution as Razer's MotionSync, which utilizes the internal SPI clock and lowers motion delay instead of increasing it. Lastly, profile management is available, too. Settings are applied and saved to the on-board memory immediately, so the software does not need to be running (or be installed) all the time. On my system, the software had a RAM footprint of 124 MB on average. Upon exiting the application, all processes are terminated, as they should be.
