Render Scale (for Sodium)

This mod is NOT a standalone utility! It requires the original Sodium mod to be installed in your game. This mod hooks directly into Sodium's settings UI and rendering backend; it will not load or function without it.

Render Scale is a client-side Fabric utility mod that allows you to change the rendering resolution of Minecraft's 3D world independently of your game window and HUD/GUI scale.

By downscaling the 3D world, you can significantly reduce the load on your graphics card (GPU) and boost your frame rates (FPS) while keeping text, chat, and inventory menus perfectly sharp at your monitor's native resolution. Alternatively, you can upscale the resolution to get high-quality super-sampled anti-aliasing.

Designed to work exclusively with Sodium, this mod integrates directly into the Sodium video settings screen.

How It Works

Normally, lowering your game resolution in the settings makes everything—including text and menus—blurry and hard to read.

Render Scale prevents this by splitting the rendering process:

1. It redirects the rendering of the 3D world (terrain, blocks, entities, skies, particles, and weather) to a custom-scaled internal buffer.
2. It copies (blits) the scaled 3D image to your screen using a direct, non-blended copy shader (TRACY_BLIT) to ensure the sky and horizon rendering remain flawless.
3. It draws Minecraft's 2D user interface (HUD, chat, hotbar, inventory, and menus) on top at your monitor's full native resolution, keeping them crystal clear.

Key Features

• Preset Profiles: Pick a configuration that suits your system instantly:
  • Ultra Performance: 3D rendered at 50% scale using the Nearest filter for maximum FPS boost.
  • Balanced: 3D rendered at 75% scale using the Linear filter.
  • Quality: 3D rendered at 100% scale (native rendering).
  • Super Sampling: 3D rendered at 150% scale using the Linear filter (reduces jagged edges and shimmering).
  • Custom: Unlocks full manual control over the render scale and filter sliders.
• Dynamic Resolution Scaling (DRS): Keeps your frame rate smooth. When enabled under the Custom profile, it automatically adjusts the 3D scale down (to your configured Min Render Scale, e.g., 50%) when performance drops to maintain your Target FPS (customizable between 30 and 240 FPS).
  • Uses an Exponential Moving Average (EMA) algorithm to smooth FPS tracking and prevent rapid, annoying resolution flickering.
• Reactivity: Seamlessly integrated into Sodium's settings. Changing profiles automatically locks/unlocks options and updates sliders visually in real-time.
• Two Upscaling Filters: Choose between Linear (for a smooth blend) and Nearest (for sharp, pixelated, or retro look).

Note 

This mod was built with a clear purpose: to bridge the gap between high visual clarity and high performance. I wanted to give players with lower-end hardware a way to enjoy smooth gameplay without making in-game text and menus unreadable, while simultaneously offering players with powerful rigs a premium super-sampling experience.
