Erik fcaff71352 docs(A.5): two-tier streaming + horizon LOD design spec ... Brainstorm output for Phase A.5. Locks key decisions: - Hardware target: 240 Hz / 1440p, 4.166ms vsync budget - Tier radii: N₁=4 (full detail, 81 LBs), N₂=12 (terrain only, 544 LBs) - Far-tier strategy: terrain-only + fog blend at N₁ (zero engineering cost) - Bucketing: tighten existing per-LB walk (Q5 Option A); persistent groups deferred to a later phase - Worker thread: single-thread mesh build off render path (Q6 Option A) - Hysteresis: existing radius+2 convention applied to both tiers - Visual ride-alongs: mipmaps + anisotropic + A2C/MSAA + depth-write audit - Acceptance: 240Hz standstill / 144 FPS walking (Q9 Option B) Spec at docs/superpowers/specs/2026-05-09-phase-a5-two-tier-streaming-design.md. Awaiting user review before transitioning to writing-plans. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>		2026-05-09 21:52:00 +02:00
