View Full Version : How to Adjust the Stereo 3D Convergence Setting in Battlefield 3

11-25-11, 08:30 AM

Since the release of the latest update for the game Battlefield 3 that added support for actually playing the game in stereo 3D mode there was a lot going on, with people liking or disliking how the game looks with the extra feeling of depth (or the lack of such). The ones that did not like the stereo 3D effect were complaining mostly that you cannot adjust the convergence in the game and the default value makes it quite flat even if you increase the depth level a lot. The reason of not being able to adjust the convergence in Battlefield 3 is that the game uses native stereo 3D rendering from the engine and does not rely to AMD‚??s HD3D technology or Nvidia‚??s 3D Vision for that, these are only used for the visualization of the stereoscopic 3D output. So hitting the Convergence hotkeys for 3D Vision for example does nothing as apparently they are not connected to the convergence adjustment of the game‚??s engine. But that does not mean you are not being able to change the convergence setting in the game, it will be just not as convenient at this moment as you will have to change a value in a config file then run the game to see the result.

Fortunately there is an interesting utility that can help you not only with the Convergence adjustment, but also with other useful settings for Battlefield 3. This free tool is called BF3 Config Utility v1.7 and you can download it from here (http://www.techpowerup.com/forums/showthread.php?t=154145) (you‚??ll need .NET 4 installed for the tool to work on your PC). But of course if it is only for the convergence adjustment you are free to do it by directly editing the config file with a text editor such as Notepad, you need to open up the file ‚??PROF_SAVE_profile‚?? that you can find in the folder ‚??Documents\Battlefield 3\settings‚?? (C:\Users\\Documents\Battlefield 3\settings).

GstRender.ShaderQuality 2.000000
GstRender.ShadowQuality 0
GstRender.StereoConvergence 1.000000
GstRender.Stereoscopy 0

In this config file you need to look for the setting called ‚??GstRender.StereoConvergence‚?? that by default is set to a value of 1.000000, you can experiment increasing it to a level that you find more acceptable and works best for you. And of course you are welcome to share what settings work best for you, so that it will be easier for other people playing Battlefield 3 in stereo 3D mode. Just don‚??t forget that the best stereo 3D experience could be achieved by a certain combination between convergence and depth (separation), so share what settings for both work best for you‚?¶
