- Resolution: 8x8 world cells, 2x2 UI cells (UI_SCALE=4) - GPU lighting: vertex-shader computed, light source list buffer (max 64) instead of O(N×R²) grid scan, O(N×S) per cell - Viewport-aware CA: iterate only active chunks, not all 250×250 - Flat array entity/item/shadow maps instead of HashMaps - Flat 128-entry ASCII atlas array instead of HashMap lookup - Partial grid upload: viewport + 30-cell margin only - Pre-allocated viewport arrays in renderer structs (zero alloc/frame) - Skip CPU lighting for GPU modes (pass None) - Benchmark mode: --mode benchmark with per-subsystem timing - GpuLightSource struct, light_count in push constants - gather_sources_in_range() for viewport-scoped source gathering Benchmark (600 ticks, release): Graphics: 531 FPS (was 386, +38%), render 1013us (was 1699us, -40%) ASCII: 402 FPS (was 313, +28%), render 1502us (was 2346us, -36%) All 171 tests + 14 scenarios pass.
