The safest all-round pick is Complementary, which looks great and stays reasonably light. Run any shader pack through Iris and Sodium for the best performance. Below are the packs worth knowing, from balanced to heavy, so you can match one to your hardware and taste, and they all run fine alongside Opal.
- Complementary is the safe default: good looks, sensible performance.
- BSL, SEUS, and Sildur's Vibrant scale from light to heavy.
- Run every pack through Iris on Sodium for the best framerate.
- Shaders run with Opal; only Lithium is incompatible.
Complementary
The popular default. Balanced lighting, good colors, and sensible performance, with profiles that let you trade looks for frames. A safe first shader for most players.
BSL
Clean, bright, and highly tunable, with a big settings menu. A long-standing favorite that scales from light to fairly heavy depending on how you configure it.
SEUS
Known for a polished, cinematic look. The heavier variants lean realistic and demand a stronger GPU; lighter versions exist for weaker machines.
Sildur's Vibrant
Comes in tiers from very light to high. The lite profiles add color and shadows without a big frame cost, which makes this a go-to for mid-range setups.
How to run them
Install Iris and Sodium
Iris runs the shaders, Sodium keeps the framerate. Put the Fabric loader and Fabric API in first.
Add the pack
Drop the shader pack in the shaderpacks folder and select it in video settings.
Opal users
Sodium and Iris both run with Opal, so you can keep shaders on with the client installed. Leave Lithium out, since it is not compatible with Opal.
Shaders plus a client
Opal is a Fabric mod for Minecraft 1.21.10, so it sits in the same mods folder as Iris and Sodium. Its glass UI is built to read clearly over a shader-lit world, so a good shader pack and the client complement each other: the world looks the part, and the interface stays crisp on top of it.

FAQ
A lighter pack or a low profile of Complementary or Sildur's Vibrant.
Yes. Run them through Iris and Sodium, both of which work with Opal. Only Lithium is the exception.
No. Iris runs shader packs and pairs with Sodium for better FPS.
