More Interesting Information About the Upcoming 3D Vision Surround

June 5th, 2010 · No Comments · GeForce 3D Vision

There are interesting things happening over at Nvidia’s forums in the topic discussing the leaked 32-bit version of the 265.76 drivers that have support for 3D Vision Surround. It turns out that if you have a triple-SLI system like the 3x GTX 470 in the picture above (the fourth GTX 465 is for PhysX and not in SLI) you can connect each monitor to a single video card for the 3D Vision Surround configuration…

The drivers seem to recognize the configuration and users are reporting that 3D Vision Surround works that way too. So if you need more processing power, and you need that for playing on 3 monitors, then you can go for 3 Fermi cards in SLI configuration and connect each monitor to each card. I’m not sure how well the 3x SLI performs compared to just 2 cards in SLI for 3D Vision Surround and I cannot test that. But more interesting is the fact that this may open a possibility to have 3D Vision Surround on 6 displays with three video cards in SLI, it will just be a matter of software support as it is now for the 3x monitor/projector mode. And three Fermi cards in SLI should give you much better performance than a single Radeon driving lets say 6 displays, although even with three cards for some games the combined resolution of six Full HD displays may still be too much, so make room for these dual-GPU Fermis that are most likely on their way already. Just a reminded, the official 25x driver that will come with 3D Vision Surround is expected by the end of this month and it should be also available in x64 version, not just in 32-bit like the leaked earlier beta.

Official 3D Vision Surround Driver R256 Launch Timeline from Nvidia

May 19th, 2010 · No Comments · GeForce 3D Vision

We now have some additional information from Nvidia, regarding the 3D Vision Surround support in the new GPU drivers version 256. It seems we are going to get an early 256 video driver in a few days (May 24th), but without support for the 3D Vision Surround, just with performance improvements for Fermi-based GPUs (GTX470 / GTX480) and then hopefully by the end of June a new driver release to introduce the much anticipated 3D Vision Surround functionality. Meanwhile all the people that already have bought 3x 120Hz gaming 3D-capable monitors for a Surround experience should have some more patience. The good thing is that when the 3D Vision Surround support comes out it should be stable enough and should work just fine, because Nvidia will have enough time to work out all the possible issues, right?

“I have been talking to a lot of our customers over the last few months and many of the most enthusiastic among them are asking when we’ll have our driver update to support 3D Vision Surround. We’re also get the same inquiries from press folks looking to do reviews of 3D Vision Surround. The fact is we are not ready yet – the surround driver needs some final improvements. When we first showed this technology live at CES in January, we expected this to become available with the first release of our 256 branch driver which was then targeted for April. Our new target for 3D Vision Surround is the end of June in a follow-on release of this 256 driver branch. Our first 256 based driver is planned to post to nvidia.com on May 24th and will enable new SLI setup controls and improve performance on several key applications for GTX 400 GPUs. When we launch the 3D Vision Surround driver at the end of June, we will provide a game list and guidance on how to get the best experience with this cool new technology. I am looking forward to it!” – Tom Petersen, Director of Technical Marketing at NVIDIA.

My First Impressions After a 3D Vision Surround Demonstration

April 26th, 2010 · 12 Comments · GeForce 3D Vision

The video above is from a 3D Vision Surround Demonstration at the Fermi Launch event in Bucharest, Romania. 3D Vision Surround Demo running on PC with dual GeForce GTX 480s in SLI, EVGA Classified Motherboard, Core i7 965 CPU, 6GB DDR3 Memory, 1200W PSU and 3x Acer GD245HQ displays. Demonstrated on the 3 monitors in stereo 3D were the games Battlefield: Bad Company 2, Just Cause 2 and Need For Speed: SHIFT, and they really looked much more immersive than when played on a single display.

The two additional displays besides the central one in a 3D Vision Surround setup are mostly covering your peripheral vision that does not get as much detail in terms of color and shape recognition and even the 3D effect is seen with less accuracy as with the central vision. But still our peripheral vision should not be neglected as it helps you detect moving objects for example and turning your attention to them if needed by turning your head towards them and getting the “full picture”. And with the 3D Vision Surround you can at any time move your central vision towards the left or right display to see the picture being displayed there if something caught your attention in the peripheral vision, like a moving object that can be an enemy or a friend unit for example. The coverage of the central vision of a normal person with no any eye issues should be somewhere around 75-95 degrees (giving you the best clear and detailed image perception) and that is enough to cover not only the central screen, but also a part of the two additional screens on the left and right in a 3D Vision Surround setup. Then the peripheral vision is extending up to almost 180 degrees and can be divided in lets say three different levels: para-central (near-peripheral), mid-peripheral and far peripheral with each of them providing different level of detail in general towards the far end of the peripheral vision. Anyway, enough with the more scientific explanation why and how our vision works, the thing is that when having three displays to cover the peripheral vision (even in stereo 3D) too the end results is much better in terms of general perception and also in terms of better immersion into the virtual game world.

And so the 3D Vision Surround was running on non-final drivers, we are waiting for the official ones to be available any time now, but the performance was Ok and there were almost no issues considering these were still beta drivers. Of course two GeForce GTX 480 Fermi cards were used to provide optimal performance and you’ll really need that in order to play the latest games on 3 displays and in stereo 3D mode. You can of course go for the bit slower GTX 470 or even high-end models from the previous generation, but you might have to consider lowering some details or the resolution in order to achieve optimal performance in the most demanding games. The setup steps and usage of the Surround looked easy to use and the bezel correction worked just fine with about 100 pixels correction needed for the left and the right side, but that also depends on the monitors being used. I also saw a demo using ViewSonic VX2268WM monitors instead of the Acer GD245HQ/GD235HZ displays and the experience did not differ much between the two.

If I have to rate the games in terms of immersion with the 3D Vision Surround setup than I’ll start with Need For Speed: SHIFT that looked simply great with the camera from inside the cockpit of the car (less impressive with an outside car view camera). Then it was the Battlefield: Bad Company 2 that also looked great and actually might give you a bit of a competitive advantage while playing with the additional two displays (at least in single played mode). And although I was least impressive with Just Cause 2 in general, it also had some scenes that were really impressive in 3D Surround and in general was more immersive than when playing in stereo 3D mode on a single display. I just hope that the 3D Vision Surround will be able to provide the same level of immersion in all other games, already available and new, and not just in the ones that were demonstrated.

Besides the stereo 3D Surround the new feature also supports the usage of 3 displays in 2D mode for work and for gaming in lets say “plain 3D” mode on all the displays, there is no need to go for 3D-ready displays if you don’t intend to play games. You can also use even 30-inch non 3D-ready monitors with resolution of up to 2560×1600 into a 3 display setup to achieve 7680×1600 or 4800×2560 resolutions (if you rotate them in 90 degrees), but most impressive is of course the availability of the stereo 3D mode with three 120Hz displays.

I hope to soon have a 3D Vision Surround system prepared for more testing and with the final 3D Vision drivers and a newer GPU drivers that would be able to squeeze even more performance from the new Fermi architecture. So stay tuned for more information about the 3D Vision Surround soon…
