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
