Precision Simulator is a fully customizable interactive VR experience in which a woman in your virtual space reacts as though she were alive.
There is no fixed story or scripted event sequence.
Give her the appearance you love,
choose your favorite positions,
and enjoy yourself at your own pace, for as long as you like.

9 positions / 68 animations / 28 eye colors / 12 hair colors / Skin tone slider / Nipple color slider / 6 environments / 6 lighting presets / 5 climax voices / 4 stages of moaning / 19 shape keys

Customization among the most extensive in the industry.
Enjoy your own character—and your own time together.

Even the demo is enough to get you off. You can literally “experience” it for yourself.

v1.0.1
- Fixed a bug that prevented the game from launching through SteamVR and similar setups.

v1.0.2
- Fixed the connection status incorrectly displaying “Disconnected” when a motorized masturbator was connected.
- Fixed bugs when applying slider adjustments.
- Fixed UI layout misalignment.
- Removed one hairstyle and added seven: two ponytails, Side Bun, Cat-Ear Bob, Uni Short, Cozy Bun, and Cat Low Twintails.
- Added a Quit button to the Environment tab.
- Added an option to automatically switch to the male viewpoint when changing positions. Available in the thumbstick-click mini menu and the Parameters tab. Pressing the primary button three times now also switches to the male viewpoint.
- Added an option for the UI to tilt with your viewing pitch, available in the Environment tab.
- Added a standing pose.
- Added saving for parameter and environment settings, allowing you to instantly restore your favorite setups.
- Added skin tone, nipple color, and makeup intensity sliders. Tanned skin is now available.

v1.0.3
- Improved brightness behavior. Previously, lighting became brighter every time the UI opened; lighting now stays at the selected level when the UI opens.
- Added lighting dimming controls.
- Added an Eye Glow slider, which makes a noticeable difference in darker lighting.
- Expanded candle controls: adjustable range, hue, intensity, and whiteness.
- Added more flexible scaling for the character, environment, and player.
Changing the player’s scale changes their position relative to the UI, which can make the controls considerably harder to use.
- Improved the UI. Scroll positions are now preserved when switching tabs, and additional panels reduce excessive scrolling.
- Improved character save slots. The slot limit has been removed, and each slot displays its hairstyle and hair color for easier identification.
- Added a Heartbeat Volume slider.

v1.0.4
- Fixed a bug that automatically saved gameplay screenshots locally. A debugging and recording feature had accidentally been left enabled. I apologize for this.
- Added support for huge breasts! The size range has increased from 0–100 to 0–400.
- Added a Settings tab at the far right to organize features.
- Added an option to enlarge only the outfit’s breasts to prevent clipping. Without this option, breasts can protrude through clothing and look unnatural.
- Added grip-based movement! The grip and primary button functions can be swapped in the Settings tab.
- Added a UI position reset. Hold the UI button—the secondary button—to bring the UI in front of your eyes.
- Moved options such as world movement and the arousal display toggle into the Settings tab, along with various other UI adjustments.

v1.1.0
- Major improvements to appearance.
- Major improvements to breasts. They now react when touched by your hands. With the UI closed, hold the grip near a breast to squeeze it, or near her head to stroke it. Both interactions increase arousal.
- Added English, Simplified Chinese, and Traditional Chinese support.
- Fixed arousal failing to increase during cunnilingus animations.
- Added support for rotary devices such as the A10 Cyclone.
- Added rapid, small movements for motorized devices during climax sequences.

A lot has changed. I’ll explain the details on Notion.
