-// *NOTE: We do not support SSE acceleration on Windows builds.
-// Our minimum specification for the viewer includes 1 GHz Athlon processors,
-// which covers the Athlon Thunderbird series that does not support SSE.
-//
-// Our header files include statements like this
-//   const F32 HAVOK_TIMESTEP = 1.f / 45.f;
-// This creates "globals" that are included in each .obj file.  If a single
-// .cpp file has SSE code generation turned on (eg, llviewerjointmesh_sse.cpp)
-// these globals will be initialized using SSE instructions.  This causes SL
-// to crash before main() on processors without SSE.  Untangling all these 
-// headers/variables is too much work for the small performance gains of 
-// vectorization.
-//
-// Therefore we only support vectorization on builds where the everything is 
-// built with SSE or Altivec.  See https://jira.secondlife.com/browse/VWR-1610
-// and https://jira.lindenlab.com/browse/SL-47720 for details.
-//
-// Sorry the code is such a mess. JC
