我只是說有新的技術可以使用,為何還要去用舊的技術??


Graphics rendering There are differences between the 32-bit and 64-bit Graphics Device Interface (GDI) that might have performance implications because of the lack of MMX support on 64-bit. Intel's MMX technology is an extension of the Intel architecture (IA) instruction set. The technology uses a single-instruction, multiple-data (SIMD) technique to speed up multimedia and communications software by processing data elements in parallel.


你可以參靠微軟的office2010 64Bit說明,


微軟的office2010 64Bit選擇使用MMX而不去使用SSE2,
結果在64Bit下效能不彰...
