MotionAssistant 1.1.83

V1.1.8.3 2023-11-30

1.    Added “Disable Turbo Boost” option in advanced settings. After checking this option, Turbo Boost cannot be adjusted. Please check this option if you are using AOC control for Turbo Boost.
2.    It is now possible to directly run the somatosensory assistant to call up the background. The previous prompt prohibiting repeated running has been cancelled.
3.    Fixed text display errors in some buttons.
4.    Optimized the XYZ axis simulation after dismantling the Lenovo split controller. Integrates acceleration, allowing any angle of rotation to point to the screen (split controller somatosensory).
5.    Added “Dedicated Configuration Lock” option. After checking, it does not switch back to the general configuration.

WinControls v1.14 + Firmware update for deadzone adjustment

WinControls v1.14 + Firmware update for deadzone adjustment

This update provides users the ability to adjust the dead-zones on devices that had them ie. Win4 6800u, 7640u, and 7840u.

Steps To Install:

1. update the firmware of the controller using the file name GPD.Gamepad.Win4.X408K407.exe (Controller has to be in gamepad mode).
2. once the update is complete, shutdown the device.
3. power on the device, install the new wincontrol app GPD.WinControls.V1.14.exe and restart device.
4. launch Wincontrol, go to mouse customization, deadzone adjustment sliders at bottom right of the mouse customization menu. (Current recommended settings by early users suggest to put both sticks to -8 on center; per Saracchini’s quick test, -8 gives about 6~8% deadzone and re-centers perfectly; -10 reduces to ~4% deadzone but causes slight jitter during re-centering)

Things To Note:

1. Version number on ZIP shows 1.14 but in Wincontrol UI shows v1.11 - this will be rectified in next update release; no impact to functionality.
2. Windows defender may falsely flagged it as malware, but as mod n1ckn4m3 has mentioned, per his checks yesterday, this is a false positive. https://discord.com/channels/243411108940087297/950574522011119707/1154484670260592651
