Add drop-in performance presets tuned for three hardware tiers. Tier targets: - Low: 4GB VRAM/iGPU, 8-16GB RAM - Medium: RX 580-class 8GB, 16-32GB RAM (shipped as pack default) - High: RTX 3060+ 8GB+, 32GB+ RAM Client configs (per tier, presets/<tier>/config/): - sodium-options.json: chunk threads, cpu render-ahead, quality - iris.properties: shaders on/off, max shadow render distance - lambdynlights.toml: dynamic lighting mode + adaptive ticking - entityculling.json: culling tracing distance - cullleaves.json: leaf culling - soundphysics.properties: reverb/ray budget (CPU cost) - flywheel-client.toml: Create backend (BATCHING vs INSTANCING) Server configs (per tier, presets/<tier>/server/): - server.properties: view-distance, sim-distance, players, compression - jvm-flags.txt: heap + G1 GC flags per RAM tier Medium configs also copied to client_pack/config/ so they ship as the mrpack defaults (bundled into overrides/config/). Docs: docs/performance.md + docs/server.md rewritten for three tiers; presets/README.md explains how to apply each tier. Default (Medium) enables shaders with INSTANCING flywheel on the 8GB GPU tier; Low disables shaders + uses BATCHING for maximum FPS on weak GPUs.
