Nvidia has introduced their new flagship GPU, namely the Nvidia GeForce GTX 780 Ti that has yet again taken the throne of the fastest single GPU video card taking the place of the GTX TITAN and according to the reviews out there beating the competition in the form of the AMD Radeon R9 290X. The video cards based on the GeForce GTX 780 Ti may not be the best in terms of price performance ratio, but they are the fastest ones and if you are looking for a solution that you might not want to upgrade for a while, then they are a great choice, especially if you are going to be using them to play in stereoscopic 3D mode using 3D Vision or playing games in 120Hz/144Hz 2D mode. Again based on the first reviews of the GTX 780 Ti that were released the card is pretty capable for playing in 2560×1600 or 2560×1440 resolution, but 4K for a single card is still a bit too much. And gaming in 4K is something that although may be very cool is still a way too expensive in terms of displays and hardware required to support it properly, so you better wait and don’t yet go investing in multiple GTX 780 Tis yet.

* The superscript numbers in green and red show the change as compared to the specs of GTX 780.

The new GeForce GTX 780 Ti is essentially a maxed out GK110 GPU with all the CUDA cores present and all 15 SMX blocks active. Comparing the GT 780 Ti spec wise to the GTX 780 you can see that the clocks of the GPU are a bit lower, but the significantly increased number of CUDA cores compensates well for that and the memory is clocked higher offering a good increase in the bandwidth. So essentially with the GeForce GTX 780 Ti we are getting a faster than GTX TITAN video card that is more affordable than the TITAN, though if you already got a GTX TITAN earlier this year there is no much need to upgrade. The recommended end user price of the GeForce GTX 780 Ti is $699 USD and it also comes with three free games as a part of Nvidia’s PIRATES, HEROES & SPIES promo bundle, the games in this bundle are Assassin’s Creed IV: Black Flag, Batman Arkham Origins and Splinter Cell Black List.

Up until a few days ago I was considering to finally upgrade my stereoscopic 3D gaming rig using 3D Vision with a GTX 780, but now that the GeForce GTX 780 Ti is out, I’ll be getting a 780 Ti card. A single card should be good enough to handle gaming in stereo 3D mode at 1920×1080 resolution and I’ll probably be sharing some benchmark results after I get to see what is the performance you will get from the GTX 780 Ti in stereo 3D mode…

The New Nvidia G-SYNC Technology Will Support 3D Vision as Well

October 19th, 2013 · 10 Comments · GeForce 3D Vision

Some good news for 3D Vision users, the just announced Nvidia G-SYNC technology will also work in stereoscopic 3D mode when playing games with 3D Vision as well by eliminating screen tearing, input lag, and stutter. All you will need to do is have a Kepler-based graphics card like at least GeForce GTX 650 Ti Boost and get a G-SYNC-enabled monitor or get a DIY Upgrade kit for an ASUS VG248QE monitor if you already have the monitor available. Nvidia says that the first DIY Upgrade modules will be shipping later this year for the most eager users willing to try the new technology. The Nvidia G-SYNC Do-it-yourself kit will cost approximately $175 USD and come with 1 year warranty. And next year we are supposedly going to see new models coming out on the market with built-in G-SYNC modules from Asus, BenQ, Philips and ViewSonic with displays even going up to 4K resolution.

Nvidia G-SYNC requires Microsoft Windows 7, 8 or 8.1 and apparently older versions of the OS will not be supported and of course it will only work with compatible Nvidia-based GPUs and G-SYNC enabled monitors, so no go for AMD graphics with a G-SYNC monitor. Multi-monitor surround configurations will also be supported if you have all G-SYNC-enabled monitors, as well as SLI setups with multiple Kepler-based GPUs that meet the minimum requirements for G-SYNC to work. G-SYNC is supposed to work with all games, though apparently some games might have issues and Nvidia will be giving the user the ability to disable G-SYNC from the control panel of the drivers on per game basis. Also games that Nvidia discovers that have trouble with G-SYNC will be disabled by default in the driver (more game profiles) and the video driver needs to be version 331.58 or higher (not yet publicly released) in order for you to have G-SYNC support available.

Note that after installing an Nvidia G-SYNC module in the ASUS VG248QE monitor and this should be also true for the upcoming monitors with the module built-in you are going to be able to use it only through the DisplayPort interface with no audio being transmitted along the video signal. Apparently only the Display Port interface allows for the tear-free, faster and smoother variable fps to be achieved when synchronizing the monitor to the output of the GPU, instead of the GPU to the monitor. Also note that the minimum refresh rate with the G-SYNC module will be 30 fps, so apparently even at 30 frames per second thing should feel very smooth and responsive all the way up to the maximum refresh rate of the monitor with in the case of the ASUS VG248QE is 144Hz.

The good news for 3D Vision users is that since the new G-SYNC technology will be compatible with 3D Vision and will also benefit from being available on monitors able to deliver 120Hz and 144Hz we are also going to see more new displays with 3D Vision supported being released. And hopefully Nvidia will start pushing 3D Vision again along with the G-SYNC technology instead on focusing only on G-SYNC. I don’t know about you, but I’m already eager to see the G-SYNC in action with 3D Vision…

Will 4K Gaming Replace Stereoscopic 3D Gaming or Not

October 3rd, 2013 · 7 Comments · Other S3D Tech

nvidia-4k-gaming

If you are already a gamer playing in stereoscopic 3D mode or are at least following what has been happening with stereo 3D you have probably noticed that lately stereo 3D gaming is being left aside and both AMD and Nvidia are focusing on 4K gaming as the next big thing in gaming. The question here is if 4K gaming will become the norm in a few years or it will have fate that stereo 3D gaming does currently have – not supported and left to the community hoping that it will keep it alive. Nvidia has done great by reviving its old stereoscopic 3D drivers and pushing both hardware manufacturers and gamers to go and try stereoscopic 3D gaming a few years ago and thus creating the big market for stereoscopic 3D gaming itself. Of course there were also other solutions already available at that time, but they did not have the needed resources and the interest in general in stereo 3D was not that strong back then. AMD on the other hand also supported kind of stereoscopic 3D, but it was “outsourced” to partners such as iZ3D and DDD, because the company never did have very strong interest in stereoscopic 3D gaming. With the boom of the interest in stereo 3D after Cameron’s movie Avatar and because Nvidia already had strong positions in the stereoscopic 3D gaming market that it has helped create, AMD had to do something more and the HD3D technology has been introduced. The problem is that AMD did not try to push game developers to support this technology (this often happens with the innovative technologies they announce) and while Nvidia has done a better job at first, lately they give the impression as they are not considering their 3D Vision technology as something they need to push anymore. So at the moment only DDD are actively developing their TriDef 3D solution and are pursuing not only stereo 3D on the PC, but also on other markets such as mobile devices and they are even offering a beta support for the Oculus Rift.

Meanwhile what happened to the market is that people yet again got interested in VR technology and gaming in VR environments mostly thanks to the Oculus Rift project and the really good feedback it got not only by consumers, but by developers as well. And just like stereoscopic 3D the Head Mounted Displays are nothing really new, they are just something that got revived yet again thanks to the recent huge boom in technology for mobile devices that allows you to pack good enough hardware in a small package and most importantly at an affordable price. The revival in the interest in VR gaming has also helped the development of various non-traditional controllers, but while the hardware is here or will soon be available the biggest issue that remains is the availability of software that will support it. With the Oculus Rift things are already moving quite well and with the introduction of the consumer version of the device in 2014 it could really be the next big thing in gaming and not 4K. Even the lower resolution development kits of the Rift have demonstrated that the resolution is not the most important thing for gaming, though it helps, it should not only be all about the resolution. The experience you are getting while gaming is way more important than to have some more pixels and that goes not only when talking about the hardware you are using, but also for the games you are going to be playing.

Let’s get back to 4K gaming and see what is happening there and why. Hardware companies already started promoting the new technology supporting 4K as 1080p or Full HD has apparently gotten old and widely adopted, so the industry needs to provide something new. Obviously increasing the resolution of a display is a good choice as you will need more powerful hardware that is capable of supporting the higher resolution, and before the technology starts to become widely adopted the prices will be high and the profit will be good. Both AMD and Nvidia will want you to buy not just one high-end video card, but two or even three in order to be able to play in 4K resolution at maximum detail levels in the latest games. And it is not only the video card, you will also need a high-end CPU, more memory, faster disk drives etc. so this will be driving the hardware market forward obviously. At the moment however not that many people are readily giving 3-4K USD for a PC and then again that much for a 4K display like the Asus PQ321QE (there are not that many options available yet) just to be able to got higher resolution.

The truth is that you can get much more realism and fun while gaming with either VR or stereo 3D and that can happen at a fraction of a cost that 4K would require at this point, so undoubtedly the question that arises here is if 4K is the next step in gaming or not? This depends a lot on how things move in the following year or two, so we need more 4K monitors becoming available and at a much lower price in order for normal consumers to start buying the hardware. For the moment 4K gaming is only for enthusiasts with deep pockets that love to brag about their PC being top of the line and it will be like that for some time. Sure it was a similar situation with stereoscopic 3D when it was reintroduced with the 3D Vision technology a few years back, it was more expensive, but not as what 4K costs at the moment. With Stereo 3D gaming it was the experience that it provided compared to playing a game on a normal 2D monitor that quickly drove people into adopting it and with 4K it is just more of the same – you get more pixels. And more pixels and higher pixel density just make the image look smoother and hard edges not so apparent even when not using AA filtering, so it does not add that much to the immersion inside the game atmosphere and making the experience more realistic like when playing a good game in stereoscopic 3D or in VR mode. So the future of 4K gaming for now is a bit cloudy and unsure and while you should not totally ignore it for the moment, you should not also jump immediately on the 4K boat either. The industry is not yet completely ready with the technology required for 4K, so it is best to wait and see what happens in 2014 before making a decision, and let us see if the sequel of the movie Avatar in 2016 will bring back the interest in stereoscopic 3D technology or maybe the wide availability of good autostereoscopic 3D solutions (glasses-free) in a few years or…
