Here are the slides of an interesting presentation Nvidia had on Siggraph 2009 about 3D Stereo implementation and usage in games and other 3D applications. Some interesting things about S3D in general and of course a little bit about 3D Vision and 3D Vision Discover. The presentation covers more the technical part of how things work and are being designed with an emphasis on some key technology challenges and how many of them are easily addressed by some basic implementation patterns. The presentation also includes some good anaglyph Stereo 3D screenshots so if you have a pair of anaglyph glasses lying around you can try to see them with the intended depth perception. Still a good read if you were unable to be attending Siggraph 2009, but you are interested in the technology and how things work. The presentation was made by Samuel Gateau from Nvidia and there seems to be something from Capcom about their upcoming Resident Evil 5 that is supposed to be optimized for Nvidia’s 3D Vision hardware. Unfortunately the slides from Capcom’s presentation are still missing.

It seems that Nvidia has done a bit of a silent update to the requirements for using GeForce 3D Vision for some tasks. Of course for gaming and 3D applications such as CoolIris you still need to have a high end GPU, but if you plan to primarily play 3D Stereo images or 3D Stereo movies on your 3D Vision you can now go for a low end GeForce 8 or 9-series video card and you should not have any problems. This is a good news for Nvidia ION-based solutions that come with GeForce 9400M video, which along with their smaller sizes and low power consumption makes them a great addition to 3D Vision for watching 3D pictures and movies. The only problem you might face with these ION-based systems is the lack of DVI output for connecting directly to a Samsung 2233RZ (if you have bigger 3D-ready TV you might be Ok) and using an adapter to convert form one type of digital output to another still might bring problems. And I’m talking about having problems with all of the first ION-based PCs such as Acer Apsire Revo R3600, AsRock ION 330 or even the very slim and tiny Pegatron Cape 7. They all have HDMI outputs which you can easily convert to DVI with the help of a special conversion adapter, but the result will not be what you expect. By using the conversion adapter from HDMI to DVI you won’t be able to set the Samsung 2233RZ display to work with more than 60 Hz refresh rate and you still need at least 100 Hz. So before thinking of some great idea combining ION system with 3D Vision for viewing 3D Stereo movies and images you better check things a bit and then decide it if is going to be Ok.

By default the game Call of Juarez: Bound in Blood does not look very good when you try to play it with GeForce 3D Vision, because there is still no profile available for the title in Nvidia’s 3D Vision drivers. Normally this may disappoint you a lot, because the game looks very nice and is not a bad title at all, but if you take some time to play with the settings you can achieve a great depth and even a pop-out effect Call of Juarez 2. And by playing with it I mean adjusting the convergence level, not by just changing some settings in the game configuration menu – there won’t be any difference in depth perception even if you go to the lowest detail level or at maximum level. The key here is the convergence level and in order to be able to adjust it you need to enable the advanced in-game settings in Nvidia’s Control Panel from the Stereoscopic 3D settings. Then you can decrease and increase the convergence level with the help of CTRL + F5 and CTRL + F6 key combinations while you are in the game (don’t mind the in-game message that pushing F5 brings out). Now set the level of depth from the controller to the minimum and continue reading on what to do…
You can set all the details to the maximum level inside the game and just play with the Post Process Quality option, because it’s two options produce quite different results in terms of graphic detail in the game. Try it out and see which one do you like better, personally I’m Ok with both… although the Simple setting provides clearer looking objects in the background (far away trees for instance). Of course you can play with these as you see fitting depending on your personal preferences and your system’s capabilities… on GeForce GTX 275 the game works at max detail level with more than enough FPS.
The key moment in achieving astonishing results with Call of Juarez: Bound in Blood is setting up the right convergence level in order to achieve both a great pop-out of the screen effect and good level of depth. Just right after you start the game in some trench in the middle of a war you need to go to your left to the wooden shelter-like thing and stand right in front of it, then look at the roof like in the picture above and start adjusting convergence level (hitting CTRL will set your character in crouch position, but don’t worry). Now, what you need to do is set the convergence level so that the closest part of the roof is not doubled (you can take of the 3D Vision glasses to make it easier), but is just a single image with and without the glasses. The far parts of the roof and the trees in the background should have a shadow when looking without the glasses again like in the screenshot above, the important part is setting the no-double look of the front part of the roof. This should give you the best results in the game both in terms of pop-out of the screen and depth perception and will definitely change the first opinion you’ve had running the game with 3D Vision.
I’m also providing two Reg files that you can directly import in your computer, they contain only the custom convergence settings I’ve created and am using with Call of Juarez: Bound in Blood. They are from Windows Vista 32-bit and Windows 7 64-bit machines, but you should be able to use them in on both OSes if you maintain the 32 and 64 bit separation. Please feel free to report if they work for you or not, but even if they don’t work out on your PC you can always achieve the same result following the guide I’ve from above.
