# Performance — Client

## Shader Tuning for 4GB VRAM

Shader loader is **Iris** (native NeoForge). Recommended shaderpack:
**Complementary Reimagined r5.4** (`client_pack/shaderpacks/`, see README).

Preset for 4GB VRAM:
- Preset: **Fast / Performance**
- Render Distance: **8** (server view-distance)
- Antialiasing: **OFF**
- SSAO: **Fast**, Shadow Quality **1.0x** (0.5x if <30 FPS)
- Shadow Distance: **64**
- Bloom: **OFF/Low**, Clouds: **2D Fast**
- Water Reflections: **Screenspace Fast**
- Colored Light / Block Light: **OFF**

If still under 60 FPS: reduce Shadow Quality to 0.5x, then disable Bloom,
before touching render distance.

## Reload rules

- Server scripts / recipes / advancements: `/reload`
- Client tooltips / JEI / textures / lang: `F3+T`
- New items/blocks (`registry_blocks.js`): **full restart**
