Atmospheric Rendering Performance Matrix

Scope: offline fixed-scene pack diagnostics. Final receiver CPU authority requires connected identical pack-off/on A/B.

  • Result: PASS
  • Source commit: fe56b6cf32c5ec0fc46fc2b5c1645d39098c1d60
  • Binary commit: fe56b6cf32c5ec0fc46fc2b5c1645d39098c1d60 (source match: True)
  • Vulkan adapter: AMD Radeon RX 9070 XT|vendor 0x1002, device 0x7550, driver 2.0.395 (raw 0x0080018B)|0
  • Frame pacing: uncapped
  • Pins: warmup 45000 ms; day group 0; world day fraction 0.5; sky phase 0 s; MSAA 0; orbit 0 m
  • Evidence window: explicit presets reset diagnostics after warmup; Auto preserves its hysteresis-owned rolling window. Every active row waits for a complete 2048-sample CPU / receiver / GPU window (300000 ms timeout).
