title: Compiling XNA to 64-bit
body: <p>I'm working on a simulator that models very complex interactions between many objects, and I mean millions.</p>
  
  <p>I've used XNA because of the useful things that it lets me do easily, especially with the rendering.</p>
  
  <p>My problem is that I'm running into <code>OutOfMemoryException</code>s after only a few seconds of simulation. I quickly realized that my program is only running in 32-bit mode, so I only get a few GBs of my somewhat larger amount of RAM.</p>
  
  <p>How can I run an XNA game in 64-bit mode?</p>
