question on ogre SIMD

Post by Nickak2003 »

I realize that ogre has been DODized, and makes use of some SIMD. Do i need to do anything in my projects to enable the SIMD? I am trying to learn more about SIMD, are there any ogre references?

As long as OGRE_SIMD_SSE2 is ticked in CMake (for x86/x64, this is the default), it should be working out of the box.

Only 32-bit float is implemented, if you use OGRE_DOUBLE_PRECISION, SIMD will be disabled.
