title: SSE2 option in Visual C++ (x64)
body: <p>I've added x64 configuration to my C++ project to compile 64-bit version of my app. Everything looks fine, but compiler gives the following warning:</p>
  
  <pre><code>`cl : Command line warning D9002 : ignoring unknown option '/arch:SSE2'`
  </code></pre>
  
  <p>Is there SSE2 optimization really not available for 64-bit projects?</p>
