Patch Adding Support for 3D Vision in Deus Ex: Human Revolution

October 20th, 2011 · 8 Comments · Stereo 3D Games

The latest patch for the game Deus Ex: Human Revolution (Build 643) is apparently what every stereo 3D gamer was waiting for as it not only improved support for 3D on AMD HD3D-based solutions, but also adds support for 3D Vision and 3D Vision Surround setups. Apparently the in-game stereo 3D controls have also been improved allowing you to get more convincing results and not to have the game looking “flat” when playing in stereo 3D mode.

Release notes for the patch:

* A fix for some players that get stuck on an infinity loading screen in Detroit.
* Fixes for some issues that caused crashes for players using specific firewall or proxy software.
* Additional improvements to counter stuttering in the game.
* Support for Eyefinity in combination with 3D when using interleaved stereoscopic monitors.
* Support for additional brands of stereoscopic interleaved monitors when using AMD graphics hardware.
* Support for Nvidia 3DVision.
* Support for Nvidia Surround, also in combination with 3DVision.
* Improved control over the stereo-3D display in the game.
– The allowed range for the stereo 3D Strength setting has been increased.
– A Stereo 3D Plane setting was added to provide additional control over the 3D effect.
* Various performance improvements.
* Fix for ‘moire’ issues seen on billboards in DX11 mode.
* Some changes to try to counter specific driver issues causing crashes in DX11 mode.

The patch should autodownload the next time you rung the game or it might have already installed, so if you try Deus Ex: Human Revolution with the new patch, then feel welcome to share your feedback about the improvements in stereo 3D support in the comments below…

Deus Ex: Human Revolution AMD HD3D to 3D Vision Wrapper (WiP)

September 7th, 2011 · 11 Comments · GeForce 3D Vision

Here is an interesting user project that is still work in progress by Rajko Stojadinovic (rajkosto). An AMD HD3D to Nvidia 3D Vision wrapper, that would allow games made to work specifically with the HD3D technology to also work with 3D Vision. So far the status of the project as can be seen on the video above shows an Over/Under split screen output from the game Deus Ex: Human Revolution with the next step to convert the Over/Under format to a Side-by-Side and activate the 3D Vision pageflipping mode. Seems as a quite useful piece of software especially if we continue to get more games with native stereoscopic 3D support in their engine that can only output the stereo 3D images to compatible AMD HD3D-ready hardware. And a good reason for 3D Vision owners to actually want to play the game in stereo 3D mode with proper stereoscopic 3D output coming right from the game engine and not generated by the 3D Vision software.

The Game Deus Ex: Human Revolution And It’s Stereo 3D Support

August 27th, 2011 · 16 Comments · Stereo 3D Games

The game Deus Ex: Human Revolution is an exclusive AMD HD3D technology title, meaning that the developers from Eidos-Montreal have partnered with AMD in order to make native stereoscopic 3D output mode compatible with the HD3D technology along with some other extra features. The game also supports AMD’s Eyefinity multi-monitor technology and is also a DirectX 11 title, although DX11 support is not exclusive for AMD-based hardware, but also works with Nvidia-based video cards. Now, what native stereoscopic 3D support means is that the game engine itself renders the slightly different left and right views that are used to create the illusion of depth in the virtual game world. Or with other words in order to have stereo 3D support in Deus Ex: Human Revolution on compatible AMD hardware you don’t need to use middle-ware such as the iZ3D Driver or the TriDef 3D software as you’d normally do in order to get a game work in stereo 3D mode with an ATI/AMD-based video card. The native stereoscopic 3D support sends the two views directly to the video driver using the quad-buffer support offered by the AMD HD3D technology, an example of what you can do by using the recently released AMD Quad-Buffer SDK.

So far, so good, however what about everyone that is using the more popular and more available alternative called 3D Vision by Nvidia? Well, they are pretty much screwed since there is no official support for stereoscopic 3D output for 3D Vision and the game does not render that well if you manage to make it work using the 3D Vision software to “convert” it in stereo 3D mode. But since the 3D Vision driver can also work in a similar way like the AMD’s HD3D quad-buffer works, it would’ve been very hard to also implement official stereo 3D output for 3D Vision. After all the game engine apparently already renders everything in proper stereo 3D mode, so it only needs to send the images to the 3D Vision for displaying on the screen. And since Nvidia apparently did not partner with the developers we get no such support, so the stereo 3D support in game becomes not so appealing feature as a lot of people already having 3D Vision are not able to take advantage of it. Or even worse, they get the game expecting it to work with 3D Vision as it is being advertised and they get disappointed, of course not reading carefully enough before pre-ordering or purchasing the game is their own fault, but still. And if you take a look at the official game forum you can notice a lot of people asking about 3D Vision support… So was the move to make the game limited to supporting only AMD’s HD3D technology while at the same time developing a native stereoscopic 3D rendering game engine? Financially probably yes during the development process, however considering the fact that the game supports stereo 3D only for PC it is a strange decision, or maybe the stereoscopic 3D support was never intended to be one of the main features of the game. However the constantly increasing number of 3D-ready PC gamers have made the stereoscopic 3D support a big topic of discussion, and that goes not only for the unhappy 3D Vision users…

A lot of gamers using ATI/AMD-based video cards and relying on middle-ware solutions such as the iZ3D Driver or the TriDef 3D software also are complaining of trouble making the game work in stereo 3D mode. And a lot of people using these solutions have ATI/AMD-based hardware, but use it with different kinds of 3D display solutions that are not supported by the use of AMD HD3D technology getting the direct S3D output from the game engine. So the situation with these users is pretty much the same as with people with 3D Vision, they don’t get that great stereoscopic 3D output as instead of getting the perfect S3D output from the game engine, they need the middle-ware solution to create the stereoscopic 3D output for them. So as a result even more people with stereo 3D solutions are left out, just because they are not AMD HD3D ready, although they may have the perfectly capable ATI/AMD-based video cards. Makes you wonder if the game developer ever think about the gamers that will be using this stereo 3D features or they think they can just say they’ve made something fancy to boost their sales. Stereoscopic 3D support for gaming on the PC is still far from perfect, there are multiple solutions available and no industry wide support present, so that you can easily make a game supporting stereoscopic 3D output for all of the available 3D displays. But most developers that are making games promoted as stereo 3D capable do try to add support for at least most of the available solutions and to ensure that this stereoscopic 3D support looks good and works well with all of them, like in the game Avatar for example.

So what can you do if you are one of the gamers with a stereoscopic 3D capable computer, but are left out by the game’s native AMD HD3D only support? Well, you need to either play the game in 2D mode or do some things in order to make it somewhat playable in stereo 3D mode. You need to start by running the game in DirectX 9 and not DirectX 11 mode, so that you would be able to use your middle-ware stereo 3D solution (3D Vision, iZ3D or TriDef 3D) with better, but far from perfect results. Another thing that you should be aware of is the fact that by default the game has its convergence preset at a specific level and you are able to only adjust the depth level. This is something that a lot of the game developers making a stereoscopic 3D title tend to do in order to provide decent level of depth and minimal to no pop-out of the image. And while this has some advantages, especially for people new to stereo 3D gaming, the more advanced users and people that have already played for a while in stereoscopic 3D mode literally hate when this happens. The reason is that they want to be able to make the adjustment of the convergence as they wish as they can easily handle more pop-out and usually want to be able to make the game pop-out, so completely locking out convergence adjustment is indeed another not recommended thing. You can warn the users not to play with it if they don’t know what they are doing and provide an easy option to reset it to the default value for example, but not completely lock it out to a preset value that you may think is the best. Now, there may be some good news for owners of 3D Vision systems as Andrew Fear has reported in the Nvidia forums earlier this month that Nvidia is cooperating with Eidos to bring proper 3D Vision support, would’ve been nice to have that right from the start however. It won’t however hurt if you mention in the official Deus Ex: Human Revolution forums that you’d like to have proper stereoscopic 3D support added to the game, not only for 3D Vision, but also for iZ3D or TriDef 3D if you are using these. But remember, in order for your post to have effect you should not use rude tone or demanding something, just say you’d like to see that support in a future update, so that the game developer can see there is actually a big demand in proper stereo 3D support from the gaming community that plays in stereo 3D mode.
