Get more FPS without making Minecraft look like a blurry mess. FSR Upscaler for Minecraft brings AMD's FSR technology to Minecraft, allowing the game to render at a lower resolution and then upscale the image to your display resolution.
Normally, getting more FPS means lowering Minecraft's resolution. While that can help performance, it also makes the game look noticeably worse.
This mod takes a different approach. Minecraft renders internally at a lower resolution, then FSR reconstructs the image at a higher resolution. Temporal upscaling uses information from previous frames to help preserve detail and reduce jagged edges.
FSR includes RCAS sharpening, which helps keep things like blocks, leaves, items, and other fine details looking sharp instead of blurry.
Rendering fewer pixels means your GPU has less work to do. This can result in a significant FPS increase, especially when playing at higher resolutions such as 1440p or 4K.
The mod can be especially useful alongside LOD mods such as Voxy. You can keep large view distances while using upscaling to reduce the amount of work your GPU has to do.
The goal of this mod is to keep the implementation as lightweight as possible and work directly with Minecraft's rendering system without requiring a large collection of additional dependencies.
Installing the mod is pretty straightforward:
.jar file for your Minecraft version.mods folder. On Windows, you can press Windows + R and enter %appdata%\.minecraft\mods..jar file into the folder.The mod can be controlled directly in-game:
Most shaders work with FSR Reloaded however, it is experimental and expect visual bugs and preformence issues. Frame gen is currently not fully supported
You can also fine-tune settings such as sharpness and resolution scaling through the mod's configuration.
The mod uses modern OpenGL features, so your GPU needs to support OpenGL 4.3 or newer.
Generally, this means:
Dedicated GPUs will generally get the most benefit, but supported integrated graphics can also run the mod.
FSR 4 has additional requirements and currently requires Windows with DirectX 12 and Vulkan support.
This mod is currently not compatible with traditional OptiFine/Iris shader packs such as Complementary, BSL, or SEUS.
The reason is that both systems need to interact with Minecraft's rendering pipeline. Shader packs replace or modify parts of the rendering process for things like lighting, shadows, reflections, and other effects, while this mod needs control over the rendering pipeline to perform its upscaling.
Running both at the same time can result in visual glitches, a broken image, or crashes.
If your priority is cinematic lighting and visual effects, use a shader pack.
If your priority is higher FPS, lower GPU usage, and better anti-aliasing while keeping the vanilla look, use this mod.
FSR isn't simply stretching a smaller image until it fills your screen.
For the temporal versions of FSR, Minecraft renders each frame with slightly different sub-pixel information. The upscaler can then use information from previous frames along with the current frame to reconstruct details that weren't fully available in a single low-resolution frame.
The result is a higher-resolution image that can look considerably better than simply lowering the resolution and scaling it back up.
