Simply Shaded is an Iris shaderpack built for one purpose: delivering the absolute lowest performance hit possible while still providing a touch of visual polish. It skips shadow mapping, composite passes, and deferred rendering entirely, leaving only a bare‑minimum shader pipeline. In testing on a typical system, the framerate dropped from 134 FPS without shaders to just 121 with Simply Shaded — a loss so small most players will never notice it.

This pack solves a clear problem for anyone who wants the mod compatibility and rendering fixes Iris offers, but cannot afford the typical 30–60% FPS reduction of even “lightweight” shaderpacks. It achieves its speed by eliminating the two heaviest stages: no shadow pass runs at all, and no full‑screen post‑processing happens every frame. The remaining gbuffer shaders only sample a texture, multiply by vertex color, and multiply by the lightmap. Nothing more.

The result is a shader that preserves correct mob hit‑flash and glow effects, works with both Iris and OptiFine, and feels almost indistinguishable from vanilla in terms of performance. It is ideal for low‑end PCs, competitive PvP players who need every frame, and anyone who simply does not want shadows dragging their FPS down.

No shadow pass — the most expensive part of any shaderpack is completely absent.
No composite or deferred passes — zero full‑screen post‑processing overhead.
Minimal gbuffer shaders — every operation is reduced to the absolute essentials.
Preserved vanilla effects — mob hit‑flash and glow rendering work exactly as expected.
Works with Iris and OptiFine — drop the pack into your shaderpacks folder and select it.

Requirements: Iris (recommended) or OptiFine. Simply Shaded has no extra resource pack dependencies and requires no configuration — just install and enjoy the lightest shader pipeline available.
