After waiting for months for my new 3D Vision-ready monitor, it finally arrived the other week. The monitor is an Alienware OptX AW2310 23″ wide screen with a resolution of 1920×1080 (Full HD). The colors are absolutely beautiful on it.
So what about the 3D? Well, to sum it up, my impression is that it is as immature as many new technologies tend to be, but an extremely cool technology nonetheless.
For those of you who haven’t heard of it, the nVidia 3D Vision system uses a fast display (120 Hz) and active shutter glasses that alternate what eye sees the image in sync with the display updates. This means that the 3D mode is only available in full-screen mode.
I had a fair bit of trouble getting the whole kit to work. The driver on the CD simply complained that my graphics card driver was too new, and left me hanging. nVidia’s product page wasn’t all that friendly either, and it took a while to figure out how to download the new drivers (while there’s a direct download link to the movie player, you’ll have to select 3d Vision as the product type for drivers).
Once in the installation and setup procedure for the driver, there was a very friendly and helpful guide that told you most things you needed to know, which was a big plus.
Getting some movies running in the movie player required installation of a codec pack, which is was completely unhelpful in not suggesting, causing a fair bit of time wasted scouring the Internet for a solution. K-Lite Codec Pack eventually came to the rescue.
Setting up 3D for games was reasonably simple for most games — simply set the refresh rate for half of the maximum (60 Hz rather than 120 Hz). Borderlands was an exception as it started completely blacked out, forcing me to find the config file and manually edit the resolution in there. I imagine this isn’t a problem if you haven’t played the game before, on a different display.
All in all, the installation process could be made a lot smoother.
My first experience with 3D came just after the installation had ended. The last screen in the setup guide had a check box titled “Show 3D image slide show after setup”. I checked it, and then proceeded to be shown a few images side-by-side in a complete failure to do anything even remotely 3D-related. In fact, the glasses never even activated.
This was, mildly said, a bit of a let-down.
The movie viewer worked a lot better, providing a very smooth experience. Sadly, you have to specify what format videos are in quite often, which would be incredibly much easier if the viewer could have shown the first frame. This leads to a guessing game, which is a fairly minor problem in the end though.
Another problem with the movie player is that it becomes unhappy if I run certain applications. In general, anything running on my second monitor or in specific anything attaching itself to the edge of the screen like an application toolbar will cause it to simply flicker and refuse to work. This problem is even worse for the 3D Photo Viewer, which simply refuses to work at all if I have the second monitor active.
Considering that most games start without a problem, writing a working photo viewer really shouldn’t be that much of a problem.
So games then…? Almost any game can be run in 3D vision mode, but nVidia has classified games into different categories depending on how well they work. Some games have a problem where certain items aren’t rendered correctly for both eyes, which can be a bit of a strain on the eyes.
The worst problem tends to be “ghosting”. Ghosting is, simply described, a shadow of the image for one eye that “leaks” into the second eye. This is said to be due to an imperfect shutter synchronization between the glasses and the monitor and due to the monitor pixels not switching colors quickly enough. I don’t believe that explanation fully — ghosting seems to be restricted to only games (movies don’t have much ghosting problems).
In addition, some games are much better than others (more on that later). My impression is that much of the ghosting effects come from a mismatch between the rendering world size and the real world, making depth effects extaggered. This means that for many games, left-eye and right-eye images differ much more than they will for a properly tweaked game or for a movie. I also wonder if V-sync has anything to do with it.
So I’ve got this amazing 3D vision rig… what do I do with it? You can watch some example photos or download a few more from nVidia’s site. The same goes for movie clips. There are a few trailers out there, but far fewer than there should be. Youtube supports 3D content, but there is no easy way to view the youtube 3D videos using a stereoscopic viewer like 3D vision.
The best 3D movie clips I’ve seen this far are trailers, like the trailer for How to train a dragon, which is absolutely spot-on. I look forwards to watching 3D movies on this setup. The problem right now is that it’s virtually impossible to get your hands on some true stereoscopic 3D movie content. The folks behind Avatar have said it will not be released in 3D “before November”… which could mean just about anything.
Which means that if you buy a 3D vision kit right now, it really has to be for the games. When it comes to games, the support really differs between games. There is some ghosting in some games, and it really depends on the game if it bothers me or not. In Dragon Age: Origins, it really did, so I will be playing through the rest of that game in 2D. I guess that style of game really means you spend a fair bit of time watching the environment, and that’s where you’ll see the most ghosting.
In Trackmania United, one of my favorite racing games, there was a fair amount of ghosting of distant things, but it really didn’t matter a single bit. The experience of mad racing in 3D totally made up for the ghosting, and when you’re driving at high speed you don’t even notice it.
Other games hardly manifest any ghosting at all. Borderlands was absolutely awesome in 3D, as the combination of the comic-book art style and 3D creates a really cool effect. Battlefield: Bad Company 2 has been certified with nVidia and received their top grade for 3D vision ready games and works just as well as that implies.
One more game to mention is Left 4 Dead 2. There is hardly any ghosting going on there either, and 3D in that game added a layer of immersion to an already immersive game. The full list of game support is available on nVidia’s site. I personally look forwards to playing Metro 2033 with it.
There are some things to note with active shutter glasses. One thing is that when they activate, things go a slight bit darker than usual, since basically your eyes will be staring at a blackened glass half of the time. You also effectively half the refresh rate of your monitor. The result is something hard to describe, almost a flicker, but not quite. This takes a bit of getting used to, but is not really any worse than watching a 3D Movie at the cinema.
The shutter glasses themselves are fairly bulky but fit nicely over normal glasses which is a plus. I’ve wore them for fairly extensive periods of time without feeling tired of wearing them. The insides of the glass reflects some light though, so if possible I recommend using them with the lights off.
It is very clear that this technology is in its infancy. I’m sure we’ll see a great development of this going forwards as it picks up momentum. The most crippling hindrance right now is the lack of movie content and the glitches in some games.
That said, playing games in 3D adds a lot of immersion for me, especially for fast-paced games like racing games or shooters. If you are looking at buying a new monitor, I definitely think you should consider buying a 3D vision capable one. The Alienware model I got was fairly expensive, but has an absolutely incredible picture when used normally as well.
