SEUS PTGI HRR
by Sonic Ether
The path-traced version of SEUS. PTGI HRR delivers near ray-tracing quality through advanced path tracing techniques, producing some of the most realistic lighting in Minecraft.
The SEUS PTGI HRR look, effect by effect
SEUS PTGI HRR ships 7 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.
Path tracing
Light bounces from surface to surface, so a red wall throws red light onto the floor beside it.
Ray-traced reflections
Reflections are traced rather than approximated, so they hold up even at grazing angles.
Ray-traced shadows
Shadows are traced per light ray, so contact edges stay sharp and far edges blur naturally.
Caustics
Sunlight bends through the surface and paints a moving net of light on the seabed.
Volumetric lighting
Light becomes visible in the air itself: shafts hang between trees and pour through cave mouths.
PBR
With a PBR resource pack, blocks gain real roughness and metalness: polished stone shines, wool does not.
SEUS PTGI HRR in short
SEUS PTGI HRR is a high-end Minecraft shader pack by Sonic Ether, 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 1.16.5 - 1.20.4.
The look is defined by full path tracing for physically accurate light bounce and colour bleed, ray-traced reflections on water and shiny surfaces, ray-traced shadows with accurate soft penumbra, and global illumination so bounced light fills shaded areas naturally. Together these effects reshape every scene, from the way morning light rakes across terrain to how water and glass catch reflections at dusk.
SEUS PTGI HRR suits enthusiasts with powerful graphics cards who want the very best image quality. Players highlight its near ray-tracing quality and accurate lighting as standout qualities. It runs through OptiFine on Minecraft Java, and its ultra-tier demands mean it pairs best with the hardware described in the requirements below.

- Ray-traced reflections: it adds ray-traced reflections on water and shiny surfaces.
- Ray-traced shadows: it adds ray-traced shadows with accurate soft penumbra.
- Global illumination: it adds global illumination so bounced light fills shaded areas naturally.
- Caustics: it adds underwater caustics that dance light across the seabed.
- Volumetric lighting: it adds volumetric light shafts streaming through gaps and trees.
- Overall direction: the result is maximum-fidelity, cutting-edge visuals, applied consistently across the whole world.

Performance and requirements
SEUS PTGI HRR 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 3060 / RX 6700 XT with 6 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 6 GB or more of VRAM.
SEUS PTGI HRR officially supports Minecraft 1.16.5 - 1.20.4. 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 SEUS PTGI HRR with little visible cost.
