- Load the proper delay-loaded dll depending on instruction support of the current platform.
- Replaced reciprocal approximation with proper division.
- This improves performance as the division is faster than a reciprocal with refinement on recent CPUs.
- This improves quality as the division provides higher precision.
- It fixes a nasty non-determinism in the DDC because reciprocal yield different results on different CPUs.
- Configured so that AVX2 and SSE2 results are exactly the same (see config.h).
- More details can be found in config.h
- 80.773s -> 47.547s for single-threaded 8k texture compression
- 18m34s -> 14m50s for recompressing all textures of Reverb P_World during level loading.
