How to enable stereoscopic 3D in Deus Ex: Human Revolution?

Solution 1:

I Couldnt get it to work by stock either, but the solution given in this forum post worked.

But, be very careful. This involves registry editing, which can be very dangerous if you get it wrong.

Click on Start button, type regedit, then click OK. Navigate to the following place in the registry (Windows 7, 64BIT. Should work in most OS's) ...

[HKEY_USERS\S-1-5-21...\Software\Eidos\Deus Ex: HR\Graphics]

and edit StereoMode, setting the value to 4.

You may have to repeat occasionally these steps, the game may reset the value back to 0 if you change any of the gfx settings.
