what is motionstabilizer fr?

Motion Stabilizer is a Windows desktop app that draws a visual overlay on top of 3D games to help reduce motion sickness. The idea is that giving your eyes a fixed reference point while the game world moves around you can make the effects of motion sickness less severe. It offers a few different overlay elements you can turn on: an edge overlay that draws a reference frame around the screen border in a box, dome, or flag shape, a center crosshair that gives your eyes a fixed focal point, and a draggable floating clock with several time formats and outlined text. All of these can be toggled on the fly using global hotkeys like F1 through F11, so you can adjust things without leaving your game. The app is described as safe and zero-intrusion. It works purely as an external desktop overlay window, does not inject any code into the game process, does not read game memory, and does not modify game files, which the author states makes it compatible with anti-cheat systems like Vanguard, EAC, and BattlEye. It does note that the overlay may not display correctly in a game's exclusive fullscreen mode, and recommends switching the game to borderless or windowed mode instead. Most users can just download a prebuilt release from the Releases page and run the executable directly, since the .NET runtime is bundled in. Building from source requires the .NET 8.0 SDK and a simple dotnet build command. Under the hood it's built with .NET 8 and WPF, using the Win32 API for features like click-through overlay windows, global hotkey registration, and the system tray icon. The project supports both Chinese and English in its interface, lets you save and load different configuration profiles, and is released under the MIT license by its author, shsr07.
