Photon Shaders 1.21, 1.19

Published on: March 29, 2026

Photon Shaders is a popular, gameplay-focused shader pack for Minecraft Java Edition. It uses a semi-realistic style that makes your world look much better without turning it into a full photorealistic game. Instead of flashy effects that hurt performance, it focuses on clean lighting, beautiful skies, realistic water, and smooth gameplay.

With over 15.5 million downloads on Modrinth, Photon has become a favorite for players who want nicer graphics while still being able to explore, build, and fight mobs comfortably. It feels natural and immersive — perfect for both vanilla players and those using big modpacks.

Features of Photon Shaders

Sky, Clouds, and Weather

  • Fully revamped sky with realistic colors and lighting.
  • Detailed clouds in multiple layers and many different types.
  • Immersive daily weather system — every day can have slightly different skies and moods.

Lighting and Shadows

  • Soft, natural shadows with variable-size penumbras (the soft edges around shadows).
  • Voxel-based colored lighting (only in Ultra profile and with Iris).
  • Detailed ambient occlusion (GTAO) that makes corners and edges look deeper and more realistic.

Water and Reflections

  • Revamped water that looks clear and natural.
  • Screen-space reflections so you see the sky, trees, and buildings bouncing on the water surface.

Atmosphere and Camera Effects

  • Volumetric fog that makes distant areas feel deep and atmospheric.
  • Bloom, depth of field (soft background blur), and motion blur for a cinematic feel.
  • Much better image quality thanks to TAA, FXAA, and CAS.

Other Highlights

  • Full support for labPBR resource packs (makes textures look more detailed).
  • Advanced temporal upscaling (helps low-end PCs run it better).
  • Huge customization menu — you can tweak almost everything.

It has Low, Medium, High, and Ultra profiles so you can match it to your PC.

System Requirements to Run Photon Shaders

Photon is well-optimized for gameplay and runs on a wide range of computers. There are no strict official minimum specs, but here’s a practical table based on player reports and developer notes:

Hardware LevelRecommended ProfileExample GPURAMExpected FPS (1080p)Best For
Low-endLow + Temporal UpscalingIntegrated graphics (Intel UHD/Iris Xe)8 GB40–70+ FPSOlder laptops — still playable and pretty
Mid-rangeMedium or HighGTX 1650 / RTX 3050 / RX 66008–16 GB60–120+ FPSMost players — smooth and beautiful
High-endHigh or UltraRTX 3060 / RTX 4060 or better16+ GB80–200+ FPSMax settings, high render distance, mods

Quick Tips

  • On low-end PCs, enable temporal upscaling — it helps a lot.
  • Apple Mac users (Metal GPUs) need to disable SH Skylight and Colored Shadows for best results.
  • Use Iris + Sodium for the biggest FPS boost.

FPS Performance

Photon is designed to be gameplay-friendly. Many players report that it runs smoother than similar realistic shaders while still looking excellent.

On mid-range hardware, you can easily stay at 60+ FPS with most effects on. High-end PCs often hit 100–200 FPS. The temporal upscaling feature is a big help for lower-end computers. Community tests on Reddit and YouTube show it performs very close to top shaders like BSL while feeling lighter during movement and combat.

Publish Date and Author

Photon Shaders was first published on Modrinth about 2 years ago (early 2024). The author, sixthsurge, spent nearly 3 years developing it before the public release. The latest stable version is 1.2a (released July 2025), with regular smaller updates since then. sixthsurge is known for listening to player feedback and keeping the pack focused on performance and beauty.

How to Install Photon Shaders

Photon Shaders Installation (Iris)

Compatibility

Photon works great with:

  • Iris Shaders (strongly recommended — needed for colored lighting in Ultra profile).
  • OptiFine (works well for most users).

It supports Minecraft versions from 1.17 up to the latest 1.21.x. It also plays nicely with Distant Horizons mod and most resource packs (especially labPBR ones). Not ideal for Apple Metal GPUs without tweaks.
