• Andy Edinborough VC2005 %50 Slower then VC2003

  I just migrated a graphics application from VC2003 to VC2005.  After building it, I ran a small benchmark & found that VC2005 code was about %50 slower. The Application does a great deal of floating point and integer calculations.  It also converts doubles to int quite a bit (the VC2003 version used SSE to handle this). The VC2003 version used /G7 and /Ow (which are not available in VC2005) Compiler Switches Used: (vc2003)/arch ...Show All
