No, eS models that include an OLED screen are designed as mice for use without software.
The OLED display on the eS model allows easy monitoring of battery levels and adjustment of key settings, such as LOD, debounce time, motion sync, polling rate, and DPI, using dedicated mouse buttons. This eliminates the need for external drivers.
Additionally, there are no plans for eS software.
However, this does not apply to eS FS-1. Since that model doesn't include an OLED screen, it is compatible with software.
