   Enable Enhanced Instruction Set in Visual Studios
  I'm trying to figure out how to enable SSE optimizations in my program.  I thought I saw an option under Code Generation in project settings once, but I don't see it anymore.  I've also tried /arch:SSE, but output tells me it's an unknown option.Anyone know?Thanks   
  Which compiler are you using?   ;  If you are using the full version of Visual Studio 8, you can go to the properties dialog of the project.  Under the Configuration Properties tree element, go to C/C++, then Code Generation.  There is a property in there called Enable Enhanced Instruction Set, that should be what you are looking for.Magius   ;  I'm using vc 7   ;  Unfortunately I don't believe VC++ 2002(7.0) supports /arch. I don't have a copy of '02 so I don't know specifically though.Both 2003 (7.1) and 2005 (8.0) fully support /arch   ;  Aww man, really?  Dang-it.  I must've seen that option at my work computer then.I have some old SSE code I wrote once to speed up my program.  I'm getting back into maintaining it and wanted to see how it compared to what the compiler generates.Thanks anyways.   ;  Well, you can always download the free VS2005 express edition. That uses the same compiler that's in the standard/pro editions and fully supports /arch:* options.   ;  Hmm, good call.  Maybe I'll check that out.Thanks   ;  You can also replace the compiler with the free Microsoft toolkit compiler.It supports /arch and you can find it here.
