Performance — Client

Three drop-in tiers are provided: Low, Medium, and High. The Medium tier ships as the pack default (matches a Ryzen 5 5600X / 16-32 GB RAM / RX 580 8 GB machine). Full details and copy commands live in presets/README.md.

Tier	Target	Shaders	Render distance	Key trade-offs
Low	4 GB VRAM / iGPU	Off	4-6	Minimal effects, most CPU headroom
Medium	8 GB VRAM (RX 580-class)	On (Complementary, Performance)	8	Balanced 60 FPS — default
High	8 GB+ VRAM (RTX 3060+)	On (Complementary, Ultra)	10-12	Max visual quality

Applying a tier

# client configs → instance config dir
cp -r presets/low/config/* ~/.local/share/PrismLauncher/instances/<instance>/minecraft/config/

Restart the game after copying. See presets/README.md for the full file map.

Shader tuning (Complementary Reimagined r5.4)

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

In-game (Esc → Options → Shader Packs → Complementary → Shader Pack Settings):

Medium (8 GB VRAM)

Preset: Fast / Performance
Antialiasing: OFF, SSAO: Fast, Shadow Quality 1.0x
Shadow Distance: 64, Bloom: Low, Clouds: 2D Fast
Water Reflections: Screenspace Fast, Colored Light: OFF

High (8 GB+ VRAM)

Preset: High / Default
Antialiasing: OFF or FXAA, SSAO: High, Shadow Quality 1.5x
Shadow Distance: 128, Bloom: On, Clouds: 3D
Water Reflections: Screenspace, Colored Light: On

Low (no shaders, or "Potato")

Play with shaders off (Iris enableShaders=false).
If you want them on, use Complementary "Potato/Ultra" preset, shadows OFF.

If FPS is still low, lower Shadow Quality / disable Bloom before touching render distance.

Reload rules
