A SIMD-accelerated frustum culler that evaluates 8 bounding box corners against 6 frustum planes using AVX2 vector registers in under 15 clock cycles.

Extracting plane equations from the combined View-Projection matrix and evaluating dot products with _mm256_fmadd_ps allows testing hundreds of entities per microsecond.

Skipping draw calls and animation updates for culled meshes keeps frame rates pegged at monitor refresh rate.
