Usually when you want to play games in stereo 3D mode you get all the required hardware and software in order to be able to play as many games as available and working well in stereo 3D mode, however there are exceptions. One such exception is if you only play an online racing simulator such as iRacing and you need to make it more realistic by playing in stereoscopic 3D mode. DDD has released a special limited version of their TriDef 3D package that is especially meant only for players racing in the iRacing online racing simulator. The TriDef 3D for iRacing will only support tht game and is available for $4.99 USD, it will work with Line Interlaced (FPR) displays, HDMI 1.4 3D TVs/monitors (if your graphics card supports AMD HD3D) and Anaglyph glasses. Of course if you already have a full TriDef 3D license you can also play the game in stereoscopic 3D mode, furthermore the online racing game iRacing is also supported by 3D Vision with an Excellent rating for the stereoscopic 3D compatibility it offers. Have in mind that the iRacing online racing simulator is not a free game, it is a subscription-based title.
