Performance Presets — SCICRAFT

Three drop-in tiers for client (and server) tuning. The Medium tier is the pack default — it ships inside the mrpack (overrides/config/) and matches a Ryzen 5 5600X / 16-32 GB RAM / RX 580 8 GB class machine.

To use a different tier, copy the files from the matching folder into the .minecraft/config/ directory (client) and the pack's server/ directory (server), then restart.

Tier targets

Tier	CPU	RAM	GPU	Use case
Low	4-core / older	8-16 GB	4 GB VRAM or iGPU	Integrated graphics, laptops, weak desktops
Medium	6-8 core (5600X-class)	16-32 GB	8 GB VRAM (RX 580-class)	Default. Balanced 60 FPS.
High	8+ core	32 GB+	8 GB+ VRAM (RTX 3060+)	High FPS at high render distance / shaders

What's included per tier

Client (`presets/<tier>/config/` → `.minecraft/config/`)

File	Effect
`sodium-options.json`	Terrain renderer: chunk threads, culling, quality
`iris.properties`	Shader loader: on/off, max shadow render distance
`lambdynlights.toml`	Dynamic lighting quality / adaptive ticking
`entityculling.json`	Entity/block-entity culling distance
`cullleaves.json`	Leaf culling on/off
`soundphysics.properties`	Reverb/ray budget (audio CPU cost)
`flywheel-client.toml`	Create/Flywheel render backend (batching vs instancing)

Note: sodium-mixins.properties is left at default on all tiers. Hand-editing Sodium mixin flags can cause crashes, so we tune the safe, supported options (sodium-options.json) instead.

Server (`presets/<tier>/server/`)

File	Effect
`server.properties`	view-distance, simulation-distance, compression
`jvm-flags.txt`	Recommended JVM heap + GC flags for that RAM tier

Applying a tier (client)

# Example: switch to LOW
cp -r presets/low/config/* ~/.local/share/PrismLauncher/instances/<instance>/minecraft/config/

Then restart the game. Shader-pack in-game settings (Complementary) still override a few visual options — see docs/performance.md.

Applying a tier (server)

# Example: switch to LOW
cp presets/low/server/server.properties server_pack/server.properties
# use the jvm-flags.txt line when launching

Notes

Shaders are disabled on the Low tier — this is the single biggest FPS win. On Low, either play without a shaderpack or use an "Ultra/Performance" preset of Complementary with shadows off.
Medium is the shipped default — the mrpack already contains these configs, so players who do nothing get the balanced experience.
enableShaderCompatibleRendering is on for Mekanism Covers on all tiers so covers render correctly with shaders.
