Ten_perf.js – Performance & Graphics Quality Plugin for RPG Maker MV

Ten_perf.js is a lightweight performance plugin for RPG Maker MV that lets players choose between Low, Medium, and High graphics quality presets.

It is designed to help MV games run better on weaker PCs, laptops, and mobile devices by reducing GPU load, saving battery, and lowering render cost when the screen is idle.

The plugin does not edit RPG Maker MV core files. It only aliases standard engine methods, making it easy to install, remove, or integrate into an existing project.

Features

• Adds graphics quality presets: Low / Medium / High
• Reduces rendering load when the game is idle
• Supports idle FPS throttling to save battery and GPU usage
• Supports render-scale reduction for weaker devices
• Keeps game logic timing untouched
• Works on both PC and mobile builds
• Optional built-in Options menu entry
• No dependency required
• No core file editing
• Includes public API for custom UI or advanced integrations

Quality Presets

Low

• 30 FPS active rendering
• 30 FPS idle rendering
• 50% render scale
• Heavy effects disabled
• Ambient effects disabled
• Best for battery saving and low-end devices

Medium

• 60 FPS active rendering
• 30 FPS idle rendering
• 80% render scale
• Heavy effects disabled
• Ambient effects enabled
• Balanced mode for most players

High

• 60 FPS active rendering
• 60 FPS idle rendering
• 100% render scale
• Heavy effects enabled
• Ambient effects enabled
• Best visual quality

How It Works

Ten_perf.js skips unnecessary draw frames when the screen is idle, but it does not slow down game logic, input, movement, events, or battle timing.

This means the game still behaves normally, while rendering can be reduced when full visual updates are not needed.

The render-scale option lowers the internal rendering resolution while keeping the game window and UI size the same. This can reduce GPU workload significantly, especially on weaker hardware.

Built-in Options Menu Support

If enabled in the plugin parameters, Ten_perf.js adds a Graphics Quality option directly into the default RPG Maker MV Options menu.

Players can switch between Low, Medium, and High without needing a custom menu.

You can also disable the built-in menu option and control the plugin from your own UI.

Public API

Advanced users can control the plugin with:

window.TenPerf.apply("low"); window.TenPerf.apply("medium"); window.TenPerf.apply("high"); 

You can also inspect the current state with:

window.TenPerf.debug(); 

This makes it easy to connect Ten_perf.js to your own settings menu, launcher, or custom performance system.

Compatibility Notes

Ten_perf.js is designed for stock RPG Maker MV projects and should be safe to drop into most games.

It is also compatible with parallax mapping setups because render scaling does not change logical coordinates. Map-bound pictures and UI elements should remain aligned.

For pixel-art games, High quality is recommended if you want to keep crisp visuals, because lower render scale can make the image softer.

Installation

1. Copy Ten_perf.js into your RPG Maker MV project’s js/plugins folder.
2. Open the RPG Maker MV Plugin Manager.
3. Add Ten_perf.js.
4. Choose your default quality preset.
5. Enable or disable the Options menu entry depending on your project.

Recommended For

• RPG Maker MV games targeting low-end PCs
• Mobile MV builds
• Browser builds where GPU usage matters
• Games with heavy maps, parallax layers, or visual effects
• Developers who want a simple player-facing graphics quality setting

License / Usage

You may use this plugin in your RPG Maker MV project according to the license included with the download.
