About CaveTunnel AntiMotion
What is CaveTunnel AntiMotion? CaveTunnel AntiMotion is a lightweight Windows utility that reduces motion sickness (3D眩晕) while playing 3D games — and doubles as a powerful window-scaling tool for stretched-resolution play styles. It draws a one-point-perspective "tunnel" mask around the center of your screen: the center stays fully transparent so you see the game, while the surroundings fade into a soft dark tunnel with converging depth lines. This stable visual frame anchors your peripheral vision, which is exactly what your brain needs to stop feeling sick during fast camera movement. Key Features Perspective tunnel mask — fully customizable: mask opacity, soft edge, corner radius, line color/width, corner lines, inner frame, 5 center shapes (rounded rect / circle / ellipse / arch / octagon), and multi-layer depth sections with gradient. Window scaling & stretching — scale any windowed game to any size or aspect ratio without touching in-game resolution. Perfect for the classic CS stretched look, vertical stretching, or filling your whole monitor. 24-inch esports simulation (beta) — replicate the exact geometry of a professional 24-inch monitor on your 27-inch (or any) display. The tool scales the play area by physical monitor size, so the crosshair geometry feels identical to what pros use. Free drag-resize — drag the 8 handles on the mask to resize your game window in real time, like resizing a webpage. The internal resolution never changes. Presets & game profiles — 10 built-in presets (deep anti-sickness, light, cinema vignette, esports, night ops, retro arcade, and more), save your own, import/export, and auto-apply per-game profiles by window title. Global hotkeys — toggle the mask, open settings, and switch presets instantly. Fully rebindable. Full gamepad support — navigate settings, virtual keyboard, and color picker entirely with an Xbox controller. Breathing guide (beta) — gentle synchronized brightness waves on mask elements to calm your focus. Custom image masks — overlay a crosshair PNG or use a full-frame image (e.g. cockpit) as your mask. Available in 30+ languages — switch anytime from the tutorial welcome page or settings. How to use Run the game in windowed or borderless mode (fullscreen cannot be scaled). Press Ctrl+Shift+O to enable the tunnel mask — it auto-locks onto the active window. Adjust everything live from the settings window (Ctrl+Shift+P).
