The New Nvidia GeForce Experience 1.6 Is Now Available

The Nvidia GeForce Experience software has been out for a while and though not very useful for gamers using 120Hz displays to play in 2D or in stereoscopic 3D mode the software could prove helpful to gamers that are not too technical and just want to have the best possible performance that the hardware in their Nvidia GPU-based PC allows. Nvidia has just released a new version of the software, a version that a lot of people expected to have the new ShadowPlay feature that the company has promised a while ago to give the gamers ability to record gameplay videos using hardware acceleration from Kepler-based GPUs. A feature that would bring FRAPS or Dxtory-like video recording features with hardware accelerated video encoding with minor performance hit and H.264-encoded MP4 videos as output (not supporting stereo 3D video recording, you’d still have to use FRAPS for S3D video recording). Unfortunately the new version 1.6 of GeForce Experience does not come with the ShadowPlay feature, instead it brings the ability to stream PC games to the Nvidia SHIELD portable gaming device (starts shipping tomorrow where it was available for pre-order) over your home Wi-Fi connection. It seems that we should wait more for the release of the ShadowPlay feature…

Actually it is not only the Nvidia GeForce Experience software that is obviously targeted at not very advanced users, it seems that lately Nvidia is too focused on mobile gaming with their Tegra and Project SHIELD,
Nvidia Grid for Cloud gaming and bringing other new features such as support for tiled 4K displays (4K monitors look promising, but these require a lot more GPU processing power than Full HD). Not that this is a bad thing, but it seems that Nvidia is not very focused on 3D Vision and stereoscopic 3D gaming anymore, or at least this is the impression that we are getting. What we know for sure is that we’d hate to see 3D Vision following in the footsteps of the old stereoscopic 3D drivers that Nvidia had back in the day. If Nvidia is not actively working on their stereoscopic 3D game support as well as with game developers, we unfortunately cannot expect too much from AMD either as they were never that active into supporting stereo 3D gaming either.

Manufacturers of computer monitors are also kind of moving away from stereoscopic 3D support available on their products and form active 3D displays supporting 120Hz and 3D Vision they are kind of moving to just 120Hz monitors targeted at gamers willing to play in 2D at the higher refresh rate. What we are seeing is a lot of new 120Hz displays that are not supporting stereo 3D, though on the passive 3D front there are still quite a lot of 3D-capable products. Fortunately the guys at TriDef 3D are still actively working on improving their software that works on all GPUs, though it does not official support 3D Vision-capable displays. Hopefully we are going to see some new good for stereo 3D things finally happening after the summer ends…

Using a 3D DLP Projector in Stereoscopic 3D Mode with a PC

The 3D DLP projectors are one of the most affordable solutions to get a large screen with 3D support, whether it is for watching 3D movies at home or for playing games in stereo 3D with a better sense of immersion. There are a lots of models available on the market using various interfaces and having different resolutions and capabilities and all of these may cause a confusion and as a result you may end up with a 3D-capable projectors that does not work the way you wanted it. There are a few very important things that you should be aware of when considering buying a new 3D DLP projector or already have one, but you still haven’t used its 3D capabilities and you want to try them out. One of the most important advantages, besides the large projected screen of a 3D DLP projector is the fact that the technology does not suffer from issues with crosstalk, unlike 3D-capable monitors or 3D HDTVs. So let us see what is the most important information that you need to know.

When talking about a consumer level affordable 3D DLP projectors there are two main types of modes being used for providing support for stereo 3D, these are frame sequential input (can be over a VGA or HDMI interface) or HDMI 1.4 frame packaging. The interface and mode being used by a 3D DLP projector is very essential on what else will you need and how can you use the projector, so you must carefully choose the right interface based on what toy are going to be using the projector for and even depending on what other hardware you have in your PC. You should be well aware of the fact that there are still no affordable consumer level 3D DLP projectors capable of providing 1080p resolution in 3D mode with high-enough refresh rate for comfortable gaming. So regardless of the interface a 3D DLP projector uses and the native resolution it supports you can forget about being able to play games in stereo 3D mode at 1080p resolution for now, but you can still watch 3D movies at Full HD resolution if the projector is with 1080p native resolution. And this is just one of the examples of the limitations and features you should be well aware of when considering to use a 3D DLP projector, especially if you still haven’t purchased one. But there are a lot more specific things…


3D DLP Projector with frame sequential support:

– You can supply the frame sequential output over VGA or HDMI 1.3 interface.
– The projector is limited to 720p resolution in stereo 3D mode as maximum.
– In order to use the projector in stereo 3D mode it has to be in its native resolution (can be up to 720p).
– Besides being able to use stereo 3D mode at 60Hz per eye, you can also use 120Hz refresh rate in 2D mode.
– You can use any standard pair of DLP Link glasses with it, there is no need for any kind of emitter as the technology uses special kind of white light flashes embedded in the image being displayed.
– With DLP Link glasses you are good to watch 3D videos with the help of any software player capable of outputting 3D in frame sequential mode such as the Stereoscopic Player for example.
– With DLP Link glasses you are not able to directly play games in stereoscopic 3D mode or watch Blu-ray 3D movies without having to meet some additional hardware requirements and use extra software.
– You can use DLP Link glasses to play games in stereo 3D mode only if you have a compatible AMD-based graphics card supporting AMD’s HD3D technology (Radeon HD 5000 series and up) together with the TriDef 3D softare.
– You can use Nvidia’s 3D Vision active shutter glasses together with their specific IR emitter to play games in stereo 3D mode if you have a compatible Nvidia-based graphics card (GeForce 8×00 series and up), you can’t use DLP Link glasses with 3D Vision.
– Have in mind that both AMD and Nvidia have a list of officially supported 3D DLP projectors, so any model out of that list may or may not work, so there is no guarantee that you would be able to use it.
– If you want to be able to play Blu-ray 3D movies then DLP Link glasses are not an option and if you have AMD-based graphics you are out of luck, all of the software players supporting Blu-ray 3D playback on PC such as PowerDVD have support only for 3D DLP projectors using Nvidia’s 3D Vision technology.


3D DLP Projector with HDMI 1.4 frame packaged support:

– You need to use the HDMI 1.4 interface on the projector
– The projector should be either 720p or 1080p native resolution, you will be limited to respectively 720p or be able to use both 720p and 1080p resolutions for stereo 3D, but wit the limitation of using 720p resolution at only 50/60 Hz 3D mode or 1080p at 24Hz 3D mode.
– Even if the projector is with 1080p native resolution, the refresh rate supported at it in 3D mode is limited to 24Hz which is good on for 3D movies, for games you still have to resort back to 720p resolution where you can use either 50Hz or 60Hz in 3D mode.
– With HDMI 1.4 3D DLP projectors you are not able to use 120Hz refresh rate in 2D mode as you can with the frame sequential models.
– These projectors still rely mostly on the standard DLP Link glasses, though there are some models available offering RF glasses as well, but due to the specifics of the HDMI 1.4 3D support the type of glasses used is of not much concern as long as the projector is compatible with them.
– The 3D DLP Projector with HDMI 1.4 frame packaged support do not have support for frame sequential input.
– You cannot use the Nvidia 3D Vision active shutter glasses with these projectors, you either need a generic DLP Link glasses or any other specific model designed for the particular projector (RF glasses for example).
– You can play any kind of 3D videos and movies, including Blu-ray 3D movies as long as you have a software 3D video player and a video card capable of supporting HDMI 1.4 frame packaged output.
– All software players with support for Blu-ray 3D movie playback such as PowerDVD will be able to play 3D movies if you have at least an a second generation Intel Core processor (Sandy Bridge) in order to have support for Intel’s InTRU 3D technology, and this means Intel Core i3, Core i5 or Core i7 CPU, Pentium processors won’t do as they don’t feature InTRU 3D support. For owners of AMD-based video cards the minimum is Radeon HD 5000 series (all AMD HD3D capable video cards should work, though some may not support GPU acceleration for Blu-ray 3D) and for owners of Nvidia-based GPUs the minimum is GeForce GTX 260 or GeForce GT 320 according to Nvidia (some of supported GPUs might not have GPU acceleration).
– When talking about gaming in stereo 3D mode, using Intel’s integrated GPUs is out of the question as they are simply not powerful enough and regarding the AMD and Nvidia-based GPUs the limitation is the same as with Blu-ray 3D movie playback above – you need ca graphics card supporting either Nvidia’s 3DTV Play or AMD’s HD3D technology that can supply HDMI 1.4 frame packaged output.
– Owners of compatible AMD-based hardware with AMD HD3D technology supported need to use the TriDef 3D software (the same as frame sequential users would), owners of Nvidia-based graphics cards need to use Nvidia’s 3DTV Play software (instead of the 3D Vision for owners of frame sequential capable projectors).
– Have in mind that both AMD and Nvidia have a list of officially supported 3D DLP projectors, so any model out of that list may or may not work, so there is no guarantee that you would be able to use it.
– Projectors relying on HDMI 1.4 frame packaged input do tech do have more input lag than models using frame sequential input for stereo 3D and while this isn’t an issue for watching 3D video on them it can be a bit of a problem for some (not all) gamers playing in stereo 3D mode.

You should note that the newer 3D DLP projectors using HDMI 1.4 for 3D support are not suitable for some owners of older Nvidia-based hardware that would work with frame sequential models for example such as the GeForce 8800 which although old is still quite popular and widely used product and quite capable for gaming in the not so demanding 720p resolution even in stereo 3D mode. And with regards to the increased input lag required for the processing of the frame packaged 3D input and the lack of support for 120Hz 2D mode the frame sequential models might still be more attractive for people that are going to be using them mostly for gaming. On the other hand 3D DLP projectors using frame sequential mode are more restrictive and hard to setup for users that are going to be using them mostly for watching movies in 3D whereas the HDMI 1.4 interface makes it much easier. For gaming in stereo 3D mode on a 3D DLP projector there is still not way to get 1080p resolution, so the far that some 3D DLP projectors with HDMI 1.4 interface are with native resolution of 1080p does not help at all as you’d still have to resort to 720p resolution when playing games in stereo 3D mode anyway due to the limited refresh rate at the higher resolution.

DDD is offering a trial version of their TriDef 3D software and Nvidia also does offer you to download a 14-day trial version of the 3DTV Play software from their website, so you can get these to try things out and if everything works then you can buy a license for the software. There is no trial version of the 3D Vision software as it is a part of the Nvidia graphics driver now and it includes only free anaglyph 3D mode, the 3D Vision functionality is tied to hardware requirements as well anyway. If you already have the IR emitter of a 3D Vision kit connected to a PC you get free 3DTV Play functionality, so there is no need to buy a separate license for that.

As you can see 3D DLP projector support overlaps quite a bit in the frame sequential models, though there are some models and brands covered by official support only by either AMD or Nvidia. Unlike Nvidia however AMD is much more open to support for projectors supporting HDMI 1.4 frame packaging as there is no official list of devices on their website. Now, if you already own a 3D-capable DLP projector that is not on the list don’t worry, there is still some chance that you might be able to make it work via a workaround solution, however you should be warned that things like IR emitter emulators, or EDID override drivers may or may not work in your case and even if they tend to work you might face different issues or problems and you never know if they won’t stop working soon. So resort to trying the different workarounds (some of which are also being discussed on this website) as a last resort if you already own a device that is not on the officially compatible list, if you are making the decision on what to buy now, better choose a compatible model fitting your needs and requirements, as this can save you a lot of trouble later on.

Nvidia’s Forums are Finally Back Online and Are Working

November 1st, 2012 · 1 Comment · General 3D News


It has been already a few months since Nvidia had some trouble with their official online community forums covering their products and services and during this time the forums were offline. The good news is that apparently the forums are now back up and working, or almost working as you still cannot login with your old username, but that should hopefully be fixed soon as well. You should get a password reset email to change the older password with a new more secure one and you will be able to login after that. The Nvidia forums have been moved from nvidia.com to geforce.com and come with a new look and feel, all of the posts and information prior to when the problems were discovered should still be there, though there could be some loss of data as well. So if you’ve missed the Nvidia forums, and especially the 3D Vision section, they are now back…

To check out what the just brought back to live Nvidia Forums look like…
