Hysteria Shaders
by ElocinDev
A high-end voxel-based path-tracing shader that combines multiple cutting-edge rendering techniques for near-photorealistic results.
What Hysteria Shaders looks like in-game
Hysteria Shaders ships 8 headline effects. Each preview below is a hand-drawn illustration of what that effect does to a Minecraft scene, not a screenshot of the pack itself - the screenshot at the top of the page is the real thing.
Voxel GI
The world is sampled as voxels so bounced light and colour bleed resolve accurately.
PBR
With a PBR resource pack, blocks gain real roughness and metalness: polished stone shines, wool does not.
Volumetric clouds
Clouds gain real thickness, catch the sun on one side and cast shade below.
Ray-traced reflections
Reflections are traced rather than approximated, so they hold up even at grazing angles.
Bloom
Bright sources bleed light into the pixels around them, so glowstone and lava actually glow.
Caustics
Sunlight bends through the surface and paints a moving net of light on the seabed.
Colored lighting
Torches burn orange, lava burns red, sea lanterns burn blue, and the room takes on that colour.
Compatibility
What you need to run Hysteria Shaders
Baseline card: RTX 3070 / RX 6800. Meters are scaled against a 12 GB VRAM / 32 GB RAM reference build.
An overview of Hysteria Shaders
Hysteria Shaders is a high-end Minecraft shader pack by ElocinDev, aimed at maximum-fidelity, cutting-edge visuals. It rebuilds the game's lighting engine to deliver ray-traced or path-traced light that resolves accurate bounce lighting and reflections, transforming flat vanilla blocks into a world with real light and shadow. It carries an extreme performance cost and supports Minecraft 1.20 - 1.21.
The look is defined by voxel-based global illumination for accurate indirect light, full path tracing for physically accurate light bounce and colour bleed, PBR support so compatible texture packs gain real reflectivity and depth, and thick, volumetric clouds with real depth. Together these effects reshape every scene, from the way morning light rakes across terrain to how water and glass catch reflections at dusk.
Hysteria Shaders suits enthusiasts with powerful graphics cards who want the very best image quality. Players highlight its incredible visual quality and advanced voxel GI as standout qualities. It runs through Iris on Minecraft Java, and its ultra-tier demands mean it pairs best with the hardware described in the requirements below.
Hysteria Shaders against vanilla Minecraft
Unlike a texture pack, Hysteria Shaders does not repaint blocks - it replaces how Minecraft lights and renders the scene. Here is what it adds to your game:
- Voxel GI: it adds voxel-based global illumination for accurate indirect light.
- Path tracing: it adds full path tracing for physically accurate light bounce and colour bleed.
- PBR: it adds PBR support so compatible texture packs gain real reflectivity and depth.
- Volumetric clouds: it adds thick, volumetric clouds with real depth.
- Ray-traced reflections: it adds ray-traced reflections on water and shiny surfaces.
- Bloom: it adds bloom that makes bright sources glow.
- Overall direction: the result is maximum-fidelity, cutting-edge visuals, applied consistently across the whole world.

How to install Hysteria Shaders
- 1Install Fabric (or Quilt) for your Minecraft version, then add the Iris Shaders mod - Hysteria Shaders is an Iris-targeted shader and needs it to run.
- 2Download the Hysteria Shaders .zip from the official source linked above. Keep it zipped.
- 3Launch Minecraft with the Iris/Fabric profile, open Options, then Video Settings, then Shader Packs.
- 4Click "Open Shader Pack Folder" and drop the Hysteria Shaders .zip into the folder that opens.
- 5Select Hysteria Shaders from the list and click Apply. The shader compiles and loads after a short pause.
Running Hysteria Shaders smoothly
Hysteria Shaders sits in the ultra-impact tier, meaning an extreme performance cost over vanilla Minecraft. It targets high-end GPUs and is demanding even on them; lower-end cards will struggle at default settings.
As a baseline it lists RTX 3070 / RX 6800 with 8 GB of VRAM and 8 GB of system RAM. Those are minimums for a playable experience - for a steady 60 FPS at a reasonable render distance, aim well above them, ideally a modern dedicated GPU with 8 GB or more of VRAM.
Hysteria Shaders officially supports Minecraft 1.20 - 1.21. Running it on a version outside that range may cause visual glitches until the author updates it, so match your client to a supported release.
If frame rates dip, lower the shadow resolution and render distance first - both reclaim large amounts of performance on Hysteria Shaders with little visible cost.
Hysteria Shaders FAQ
What do I need to run Hysteria Shaders?
Hysteria Shaders is an Iris shader, so you need Fabric (or Quilt) plus the Iris Shaders mod. On the hardware side it lists RTX 3070 / RX 6800 with 8 GB of VRAM as a baseline.
Is Hysteria Shaders good for low-end PCs?
Not really. Hysteria Shaders is an ultra-impact shader built for capable hardware. Low-end machines can technically launch it but will struggle to hold a smooth frame rate.
Which Minecraft versions does Hysteria Shaders support?
Hysteria Shaders officially supports Minecraft 1.20 - 1.21. For the smoothest experience, run a Minecraft client within that range alongside a matching version of Iris.
What are the downsides of Hysteria Shaders?
The trade-offs worth knowing before you install are extremely demanding and iris only. For most users the visual payoff outweighs these, but they are the points players raise most often.
How do I install Hysteria Shaders?
Add Fabric and the Iris mod, then drop the Hysteria Shaders .zip into your shaderpacks folder and select it under Video Settings, Shader Packs. Full steps are above.
What is Hysteria Shaders best for?
Hysteria Shaders is a high-end shader that delivers ray-traced or path-traced light that resolves accurate bounce lighting and reflections. It is ideal for enthusiasts with powerful graphics cards who want the very best image quality, and like other Minecraft shaders it is free to download from the official source linked above.
