New Approach In Making Games Work Better in Stereo 3D Mode

February 6th, 2012 · 5 Comments · Other S3D Tech

How often does it happen that when you run some new game in stereo 3D mode it looks almost perfect, but there are just one or two small things that don’t look Ok in stereo 3D and this ruins all the experience, so you have to revert back to playing in 2D mode? The answer to this question is very often and just a few games make things better by offering you an advanced options menu or config file that you can use to turn off some of the extra details or effects in order to get rid of the problematic things in stereo 3D mode, so that the game can be fully enjoyed with the added perception of volume. Moreover not a lot of game developers do address issues in their games related to stereoscopic 3D rendering in their patches, so the ever growing community of stereo 3D gamers is left alone to find alternative ways to fixing things…

One new such alternative, made by the user -=HeliX=- in the Nvidia Forums, is a DirectX 9 wrapper DLL file that can give you the ability to modify the pixel and vertex shaders in games using DirectX 9. The wrapper comes in two versions, one a Debug to find and save the problematic shaders and another Release version for when you just need to run a game with the modified shaders. Now, the idea is that when running a game in stereo 3D mode using the Debug wrapper and you find something not rendered properly in stereo 3D, you would be able to save the problematic shader and then you have two options – either fixing the shader yourself (not something most people can do) or deleting the contents of the shader, so the next time you run the game via the Release wrapper you will either have the shader rendered properly or it will not be shown anymore and the game will look better in stereo 3D mode, and after finding the few pixel and vertex shaders that are causing the issues in the game it might become much more stereoscopic 3D friendly. The author has also provided an example fixes for some of the issues inside Assassin’s creed Brotherhood and Dead Space along with the two versions of the DLL wrappers, so you are ready to go and try this solution. There is a more detailed explanation on how to use it in the dedicated topic in the Nvidia Forums, you can read all the details following the link below. Since this wrapper has been developed for use with 3D Vision, it might not work well with other solutions for rendering games in stereoscopic 3D mode such as the iZ3D driver or DDD’s TriDef 3D Ignition.

User Fix For The Stereo 3D Crosshair in Battlefield: Bad Company 2

August 6th, 2010 · 6 Comments · Stereo 3D Games

Battlefield: Bad Company 2 is an official 3D Vision Ready game title which in theory means that the game should play perfectly fine in stereo 3D mode with 3D Vision and look great on top of that. However the road that the game needed to go through was a bit long and hard, there was a day 1 patch to address some issues in stereo 3D mode and after that a few more patches that improved the stereo 3D experience making the game better…

However for a bit over a month now there has actually been a regression in that since the latest update version 553292 that as been out for over a month already actually brought back some issues when the you play the game in stereo 3D mode. Mainly the issue of the crosshair being rendered in 2D mode again, although with earlier patches it was working perfectly fine being rendered in stereo 3D mode. And since this is a quite serious problem for a lot of users playing in stereo 3D mode (and something you will not expect from a 3D Vision Ready title), the fact that it is not being addressed with a proper patch in a timely manner is actually very strange. The good thing is that there is a working workaround that fixes the problem by replacing one of the game files with a version from a previous patch that brings back the crosshair rendering in stereo 3D mode.

You need to download the file package.mft from the link below and replace the currently present file in the folder where you installed the game under \Dist\win32 for example if you installed the game in the default folder it should be C:\Program Files (x86)\Battlefield Bad Company 2\Dist\win32) and that is it, you are ready to go. The file is from the game patch version 529843 and you can thank the user metti from the Nvidia forums for discovering this fix and sharing it with us, so you should try it out now while waiting for the game developers to address the issue with a new patch. Have in mind that this is for single player mode, and although it will work in multiplayer too it may create some issues in multiplayer mode!

Workaround Solution for Viewsonic PJD6531w Users with 3D Vision

June 20th, 2010 · No Comments · GeForce 3D Vision

Nvidia has provided a temporary solution for the owners of the Viewsonic PJD6531w 3D DLP projectors and 3D Vision running into problems when setting up 3D mode using the 3D Vision wizard.Have in ind that what they’ve published is just a temporary workaround until a fix is made available (probably with the release of the next driver update). The step by stem guide available as a knowledgebase article will give you directions for configuring the Viewsonic PJD6531w with the Nvidia 3D Vision glasses and it is available here: I am having trouble setting up the ViewSonic PJD 6531w using CD v1.29 (v257.21)?

The cause of the bug is that the software is choosing the optimal mode reported by the projector which in case of the Viewsonic PJD6531w is 1280×800. However, the projector needs to run at 1280×720 rezolution @ 120Hz and thus the wizard will report an error. Nvidia is hoping to have a fix for that issue ready by the next 3D Vision driver update and meanwhile if you already bought Viewsonic PJD6531w projector, then you can use the temporary workaround for the time being…
