Super Resolution Mod for Minecraft

Overview

This mod integrates multiple super-resolution algorithms into Minecraft to enhance performance or visual quality, with compatibility for most modern GPUs.

Built-in Algorithms

• AMD FidelityFX Super Resolution 1 (FSR1)
• AMD FidelityFX Super Resolution 2 (FSR2)
• Snapdragon Game Super Resolution 1 (SGSR1)
• Snapdragon Game Super Resolution 2 (SGSR2)

Compatibility

Hardware Requirements

• OpenGL 4.1+ required
• OpenGL Extensions: GL_ARB_direct_state_access GL_ARB_gl_spirv GL_ARB_clear_texture
• Game will exit if OpenGL <4.1 detected
• Always update GPU drivers, especially for older cards

OS Support

• Windows: Fully supported
• Linux: Fully supported
• macOS: Planned

Mod Compatibility

✅ Supported: Sodium, Iris, DistantHorizons, Embeddium
❌ Incompatible: OptiFine, Canvas, VulkanMod

Usage Scenarios

Performance Mode

• When experiencing poor FPS (e.g., <30 FPS)
• Set SR ratio >1.0 (e.g., 1.7×)
• Typical gain: 2-3× FPS boost with moderate quality loss

Quality Mode

• When targeting visual fidelity
• Set SR ratio <1.0 (e.g., 0.83×)
• Acts as advanced anti-aliasing
• Warning: Avoid extreme values (<0.6×) to prevent instability

Resolution Logic

For window size 1920×1080:

• SR Ratio 1.2× → Render Resolution 1600×900
• Quality = 1/1.2 ≈ 83.33%

FAQ

Q: Why still low FPS in benchmarks?

A: Tests used a 2014-era GTX 750 (1GB VRAM). The mod tripled FPS from unplayable 6 FPS to 19 FPS at 1080p with acceptable quality loss.

Q: Can this improve visuals?

A: At SR ratios ≤1.0, it enhances edge clarity through super-resolution algorithm while maintaining native resolution.

Q: Future DLSS3 support?

A: Planned after solving:

1. Motion vector generation
2. Vulkan/OpenGL texture sharing

Q: Stability status?

A:

• FSR1: Production-ready
• FSR2: Production-ready
• SGSR1: Production-ready
• SGSR2: Experimental

Q: Version support?

A: Currently 1.17+ only. Loader support:

• Fabric
• Forge
• NeoForge

Q: Ideal hardware?

A: CPU-bound systems with:

• Strong CPU + weak GPU
• Shader-heavy workloads
• Minimum: OpenGL 4.1-capable GPU (2012+ discrete GPUs)
