* Only works on machines with a Qualcomm Snapdragon 8cx Gen3 or above. Older generation devices are not and will not be supported due to some driver issues * Requires VS2022 for building. * Uses new MSVC preprocessor for sse2neon compatibility. * SIMD is not enabled, waiting on conversion of blenlib to C++.
