Finally Doing Some 3D Vision Surround Testing on 3 Monitors in 3D

April 10th, 2011 · 7 Comments · GeForce 3D Vision

3D Vision Surround is a nice additional feature that you can take advantage of for more immersive stereoscopic 3D gaming if you have an SLI setup or a Dual-GPU video card and three 3D-capable displays – 3D monitors or 3D projectors. In the case of three Full HD 3D monitors you get a wider horizontal working area with a total resolution of 5760×1080, covering your peripheral vision better in games and giving you more working area. It sounds really promising and my impressions from the few demonstrations of the technology, where I’ve seen and tried it with a few games were quite positive, but of course sooner or later I had to make a 3D Vision Surround setup to dou some more extensive testing…

It has turned out quite hard to get three 3D monitors of the same model just for testing, so I invited a friend to bring his own 24-inch Acer GD245HQ and together with the other two monitors I’ve managed to get we started testing multiple games yesterday and it was a long day. Originally I planned to do the testing in 3D Vision Surround mode with the GeForce GTX 590 video card, but do to some hardware trouble with the test system used for the 590, I had to change the idea on the go and move to my test PC with dual GeForce GTX 580s in SLI. I’ve had a big table planned for the three monitor setup, and we barely managed to fit the monitors on it… 3D Vision Surround setups even with 24-inch monitors do need a lot of space for comfortable use, and if you plan to do it with the new 27-inch monitors, you should really have a lot of free space. Other than that the setup and installation was quick, easy and problem free in general, so we moved to the testing phase and sometime early in the morning today we’ve finished with going through about 30 games in 3D Vision Surround. During the testing there were some interesting, unexpected and surprising results, so you should be prepared that not every single game will work problem free, some require a bit of tweaking and a few just don’t work. In general however the experience when everything works out is great and you quickly start to not pay too much attention to the bezels of the screens and get fully immersed in the gaming.

You can expect more photos and the results later on, as now I need some more coffee, to disassemble the test setup and pack the monitors up for returning them. I can say I’m quite happy with the results, although the whole thing was not entirely problem free. But I’m still having a hard time judging which one I like better, a single 50-inch 3D HDTV or a 3D Vision Surround setup with three 24-inch 3D monitors, because both have their advantages and their disadvantages. In the end, I’m going back to my single 3D Full HD monitor for my gaming needs in stereo 3D mode with 3D Vision as a preferred choice for now…

3D Vision Best Practices Guide by Nvidia for Software Developers

October 17th, 2010 · No Comments · GeForce 3D Vision

Nvidia has released a best practices guide for software developers that is intended to help them deliver the best possible stereoscopic 3D experience to their users. The guide contains an overview of how the automatic 3D Vision technology fits into existing technology stacks, common problems that arise when using the solution for automatically providing stereoscopic 3D mode in games, and most importantly how to easily work around those issues. It is not that hard to make sure that the software you are working on, being a game or other 3D application, is going to be rendered correctly when displayed on a 2D surface such as a computer screen or projector or being shown on a stereo 3D capable display. And why not to devote some attention to the most common issues that people that already play games in stereo 3D mode on their PC do hate to see in new titles and this is making them not want to buy a game, just because it is not working well in stereoscopic 3D mode. Of course Nvidia is not the only player in the stereo 3D market for PCs, but their 3D Vision technology is still the most popular one and quite a lot of their recommendations to avoid certain potential problems do apply for other solutions as well.

Game developers are already starting to see the potential that stereo 3D gaming can bring and are slowly going in that direction, but besides titles that are specially worked on to ensure good 3D compatibility or to provide native stereo 3D support, still for most other games there is no attention whatsoever dedicated to ensuring that they can be comfortably played in stereo 3D mode. Nobody is talking to have them completely issue free as this also may require additional testing and development meaning more time to market, but by following some basic principles and not going through the “shortcuts” in making things faster or easier, just because nobody will notice in 2D does not mean that it will be the same when you play the game in stereo 3D mode… or at least when you try to. So if you take care of the basic stuff to ensure lets say good compatibility with the automatic stereo 3D solutions for PC gaming, then later on you can release patches to improve things for the constantly growing stereo 3D community by also getting feedback from them. This process of learning on the go from each other may help a lot in speeding and widening the adoption of 3D technology as well as getting more and better 3D content, so does it sound like a win-win situation to you? And as it is said “Content is King”, however 3D content is still lacking behind the big amounts of different 3D-capable hardware base that is constantly increasing and things should go hand in hand. But enough rambling on that, if you are interested in what tips Nvidia has for the developers wanting to ensure compatibility with 3D Vision you can check the guide in PDF format. You can also take a look at another new guide, also intended for developers, that is covering some specifics regarding the more recent Nvidia Surround technology that users three monitor or projectors in 2D or stereo 3D mode to provide bigger visual workspace which can lead to better productivity or more imemersive gaming.
