Makefile Options

VortexGE is optimized for Pentium 4 computers which utilize MMX, SSE, and SSE2. The default makefile options uses these compiler options to optimize VortexGE for Pentium 4 :
-march=i686 -mmmx -msse -msse2 -mfpmath=sse

If other processor than Pentium 4 is used, for instance Pentium 3 which does not have SSE2, those macros can be changed to :
-march=i686 -mmmx -msse -mno-sse2 -mfpmath=sse
and for Pentium 2 which does not have SSE nor SSE2 : 
-march=i686 -mmmx -mno-sse -mno-sse2 -mfpmath=387

Those options can be changed by editing the makefiles.
