Vjoy Mouse Steering Today

is a niche but powerful technique that allows PC gamers and sim racers to emulate a steering wheel axis using their computer mouse. While hardware wheels (like Logitech or Fanatec) offer force feedback, they are expensive. A keyboard offers only binary input (full left/full right), which is unrealistic. Gamepads offer analog sticks, but lack precision.

| Parameter | Effect | Recommended Range | |-----------|--------|-------------------| | | Higher = less mouse movement for full lock | 8–20 (relative mode) | | Smoothing | Low-pass filter on mouse input | 0–2 frames average | | Deadzone | Ignore tiny mouse movements at center | 1–3% of axis range | | Return-to-center | In relative mode, manually drag mouse back | Not auto (use absolute mode for auto-center) | | Non-linearity | S-curve steering response | Use game’s built-in steering curve | vjoy mouse steering
