As news of the 3D version of the Batman: Arkham Asylum hit, Kotakuite deanbmmv pointed out that people who bought the PC version of the game don’t need to re-buy it because there’s already a way to play it – and other PC games – in 3D for free… as long as you have an NVIDIA graphics card.
The NVIDIA driver will use anaglyph images – red and cyan, as shown above – to produce the 3D effect, and of course you’ll need to wear glasses with red and cyan filters to see the effect. If you’re not okay with that, then skip the rest of the article. If you’re fine with that, the first thing that you should do is to make sure that you have the latest NVIDIA drivers.
You can go to NVIDIA’s website to download the drivers. Once you’ve done that, restart your computer, then navigate to “Start>All Programs>NVIDIA Corporation>3D Vision and click on “Enable 3D Vision Discover.” All that’s left to do is to test it on your games; deanbmmv says that if your game uses DirectX, then it can probably be played in 3D.
