Vulkan Upscaler Mod

DLSS 3.7 & FSR 3.1 for Minecraft

The Vulkan Upscaler Mod leverages Minecraft's new experimental Vulkan renderer backend to introduce industry-leading upscaling and frame generation technologies. Enjoy ultimate smoothness and stunning performance without ever compromising the sharpness of your user interface!

Key Features

NVIDIA DLSS 3.7: Native integration of Super Resolution and Frame Generation. Multiply your framerate if you own a compatible RTX graphics card.
AMD FSR 3.1: Full support for FidelityFX Super Resolution and frame generation, offering massive performance gains across a wide range of hardware (AMD, NVIDIA, and Intel).
Pristine Interface (HUD): Unlike standard resolution scaling, this upscaler intercepts the 3D world render output exclusively. Your hotbar, inventory, menus, and text are rendered over it at your pure native resolution for absolute clarity.
On-the-fly Configuration: Simply press the U key in-game to instantly open the Upscaler Configuration Menu. Tweak sharpness, swap upscaling modes, and toggle frame generation in real-time.

System Requirements

To ensure the mod runs correctly, your system must meet the following criteria:

Component	Requirement
Minecraft	`>= 26.2` (Must be a Snapshot/Alpha containing the Vulkan backend)
Mod Loader	Fabric Loader `>= 0.18.x` + Fabric API
Operating System	Windows 10/11 64-bit
DLSS Hardware	NVIDIA RTX 20-series or higher (RTX 40-series required for DLSS Frame Gen)
FSR Hardware	NVIDIA RTX 20-series+, AMD RX 5000-series+, or modern Intel Arc

Note: Linux support is currently in development and will arrive in a future update!

Installation Guide

We designed the installation to be completely "Plug & Play". The required native runtime is bundled directly inside the mod.

Download the latest vulkan-upscaler.jar file.
Drop the file into your .minecraft/mods folder.
Important: Make sure you also install YACL (Yet Another Config Lib) to access the settings menu.
Launch the game! The mod will automatically extract the necessary native resources on its first launch.

You can monitor the upscaler's runtime state and fallback messages directly in-game via the F3 debug screen.

Roadmap

Thanks to our hybrid JNI Bridge architecture, the mod is built to scale. Here is what we are working on next:

Native Linux Support: Production support validation and proper native artifact packaging.
Ray Tracing / Path Tracing: The central extension point is already in place. Once the Minecraft Vulkan backend stabilizes, the mod is structurally ready to support RT/PT capabilities!
