Description:
Profile and optimize the complete cloud system to hit 2ms target consistently.
Tasks:

  • Add GPU profiling timestamps
  • Measure each cloud pass
  • Identify bottlenecks
  • Optimize: switch to cheap samples at alpha > 0.3
  • Optimize: early exit when alpha = 1.0
  • Optimize: skip regions with consecutive zero density
  • Tune march step counts (64-128)
  • Tune light sample counts (6 per step)
  • Reduce instruction count where possible
  • Test on target hardware
  • Create performance budget breakdown

Acceptance Criteria:

Full cloud system runs in ~2ms
No frame drops during normal gameplay
Optimization switches work correctly
Performance stable across different scenes

Related Issues: Depends on #30
Estimated Time: 3-4 days
