Phase 1 profiling: hooks transformMatrix4x4 (0x714260) to measure call frequency, early-exit rate, cycle cost, bone counts, and recursion depth. Dumps stats every 500 calls. Decompiled and analyzed all 11 inner functions. Key findings: - findInterpolationIndices already has good temporal coherence (linear scan) - Matrix math (scale, translate) uses x87 FPU — SSE candidates - Game already has SSE matrix multiply used by rotateMatrixByQuaternion - interpolateAnimationKeyframes does 4-component lerp — textbook SSE
