DERCODE is a realistic and fantasy shader pack for Minecraft Java, built on the Derivative shader and run through Iris or OptiFine. DureXXX and Skeeder461 author it, with M1zore, Frs0n and _Sone4ka_ credited as recoders. The stated goal is better graphics performance and effects overall. Bedrock cannot run it.
Shader loaders and versions
- Iris: Minecraft 1.16.5 to 26.1.2.
- OptiFine: Minecraft 1.20.1 to 26.1.2.
Performance and settings
The creators publish their own frame rate figures for Minecraft 1.21.11 with Sodium and Iris, at Full HD and 22 chunks, with 4 GB of RAM as the stated baseline. They are one team's measurements, not a promise for your hardware.
- GTX 1650 laptop (4 GB) reaches 100 to 130 fps.
- GTX 1660 Ti (4 GB) reaches 80 to 100 fps, and the creators blame its limited VRAM.
- RTX 2060 (8 GB) reaches 100 to 130 fps.
- RTX 3090 reaches 130 to 170 fps, and RTX 4090 reaches 210 to 270 fps.
- RTX 5060 (8 GB) reaches 120 to 150 fps, which the creators flag as a weak result for that card.
How to install DERCODE
- 1.Install Iris on Fabric or NeoForge, or install OptiFine instead.
- 2.In Iris, open Video Settings, then Shader Packs, and select DERCODE. OptiFine uses its own shader menu.

Questions about DERCODE.
4 questions
How do I install DERCODE?
Install Iris (on Fabric or NeoForge) or OptiFine, then drop the DERCODE .zip into the shaderpacks folder. Open Video Settings, choose Shader Packs, and select it. Sodium alongside Iris is the setup the creators use for their published frame rate figures.
Does DERCODE work with Iris and OptiFine?
Yes. The pack lists builds for both loaders. The newest release, DERCODE 2.2, requires no other mods or libraries. It is a Java Edition pack, so Bedrock players cannot use it with either loader.
Is DERCODE good for low-end PCs?
The creators report 100 to 130 fps on a GTX 1650 laptop with 4 GB of VRAM at 22 chunks and Full HD, using Sodium and Iris on 1.21.11. A GTX 1660 Ti with 4 GB drops to 80 to 100 fps. Treat these as the creators' own measurements.
Is DERCODE the same as the Derivative shader?
DERCODE is based on the Derivative shader and recoded by DureXXX and Skeeder461 with other contributors. Its stated focus is graphics performance and effects overall, and its changes are documented in the changelogs. It is a Java Edition pack that runs on Iris and OptiFine.
