Mass Effect 3 Demo is Out, Not Great in Stereo 3D Mode with 3D Vision

February 15th, 2012 · 21 Comments · Stereo 3D Games

Just a few hours ago EA has made available the demo version of the upcoming game Mass Effect 3, you can download the demo through Origin, and as ME3 is among the games that I’m eagerly anticipating I was in a hurry to also try it out in stereo 3D mode with 3D Vision. Unfortunately as soon as the game started I was a bit disappointed with a few things that were not even stereo 3D related, like the lack of many graphics options or the fact that some of the textures in the game were quite low quality. For more graphics options you can find in the game folder an executable called MassEffect3DemoConfig.exe that will give you some more options, and considering the fact that this is just a demo, the actual game could be better… at least I hope that we get high resolution textures there as well. As for the stereoscopic 3D support with 3D Vision… another bigger disappointment as Mass Effect 3 suffers from pretty much the same issues as the previous game in stereoscopic 3D mode, so apparently not much done to improve it here.

There is an issue with the rendering of shadows in stereo 3D mode and more specifically the dynamic shadows that you can fortunately turn off from the options menu in the game, but that is pretty much the thing you can easily do to improve how the game looks in stereo 3D mode. The HUD contains quite a few 2D elements, and that goes not only for the crosshair, but for character and enemy target markers, some objective markers and texts as well. There are issues with some post processing effects such as fire, lights, fog, smoke etc that may not be rendered correctly in stereo 3D mode and that also can cause the appearance of transparent halos around characters. The latest beta drivers 295.51 from Nvidia still did not have a 3D Vision profile for the game, there was a SLI profile added in them for ME3. Convergence is not locked in the game, so one good thing, but also something that hints that stereo 3D support wasn’t even considered as a feature for Mass Effect 3. So things aren’t looking that good for everyone willing to play Mass Effect 3 in stereo 3D mode with 3D Vision. There is still some time, although not much, before the game gets released early next month, so there is high probability that we are going to be playing it in plain non-stereoscopic 3D mode.

The PC version of the game Mass Effect 3 is available for pre-order at $59.99 USD…

Make Your Passive 3D Monitor or 3D HDTV Work with 3D Vision

February 11th, 2012 · 184 Comments · GeForce 3D Vision

Not that long ago Nvidia has introduced their “Optimized for Geforce” program that allows some certified passive 3D monitors such as Acer HR274H and Acer GR235HA to work with the 3D Vision video drivers, allowing you to use the full 3D Vision functionality with a passive 3D display. Prior to that in the old stereoscopic 3D drivers Nvidia had support for passive 3D monitors from Zalman, and although the newer Zaman 3D monitors were bundled with the iZ3D driver and not anymore with 3D Vision, they actually do work with 3D Vision and get optimized for the Optimized for GeForce functionality. If you have a passive 3D LCD monitor or even a passive 3D HDTV that is not supported by 3D Vision (Optimized for GeForce) you can actually quite easily make it work by installing a monitor driver with EDID override that will tell Windows and the video drivers that you actually have a different compatible display.

Here is an example using LG’s D2343P passive 3D monitor with installed Zalman ZM-M240W 3D Monitor EDID Override and the LG gets recognized as a Zalman 3D monitor. You need to install the INF driver from the link over the monitor driver you currently have installed from the Windows Device Manager, using the Have Disk option and if when get a warning message just confirm that you want the driver installed anyway. After that you may have to restart Windows in order for things to start working and the Nvidia video drivers to be able to properly recognize and activate the 3D support.

Opening the Nvidia Control Panel and going to the Stereoscopic 3D settings page you should see the “Optimized for GeForce” logo if everything is working properly and clicking the Test Stereoscopic 3D button should bring the Nvidia 3D test on the screen that should be working just fine when you put on the passive 3D glasses that came with the monitor. After that you can the 3D Vision Photo and Video Player and even play games in stereo 3D mode just like you would with an active 3D display and with the 3D Vision glasses. Of course using passive 3D would mean that you would have some limitations like the half vertical resolution when in 3D mode, the lower vertical viewing angle etc., but still you will be able to use passive 3D displays with your Nvidia graphics card and with all the features that 3D Vision offers, an not only with the iZ3D or the DDD TriDef 3D drivers, so you will simply have one more alternative available. I’ve tested this method and it works just fine even with the latest 295.51 beta video drivers from Nvidia, so you should have no trouble making it work. If you try this on your passive 3D setup, feel free to share your feedback and how it works with your specific 3D hardware, thanks to Butmuncher for finding out about this method.

Update: Since the Zalman EDID override does not support audio for HDMI connection to the monitor, you should use this driver only for DVI connection to the passive 3D display. If you wan to use HDMI connection and have audio over the interface as well, then you should install the Acer EDID override driver. Both INF files are included in the archive below, and special thanks to Greg Gilbert for providing the dump from the Acer HR274H display.

Here you can download the EDID override INF files that you would need for this to work…

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.
