I'm sure you enjoyed our in-depth article on the progression of 3D technology, and in case you missed it, you can read it here. Gone are the dorky glasses that we've seen in the past, now say hello to a very trendy looking 3DVision goggles from NVIDIA. Yes, 3D gaming or 3DStereo, that's how NVIDIA likes to call it, has finally hit our shores bringing new life to old games and making newer games even more fun.
So how does it work?
There are three primary requirements you will need before you go 3D.
3D Glasses
First and foremost you need the glasses that will help you view images and video in 3D. Unlike the previous red and blue glasses, the Nvidia 3DVision sports liquid crystal (LC) lens that can each open and close 60 times a second. When I say open and close, there is no mechanical shutter but instead the lens goes on and off that many times.
But in order to draw 60 frames on each lens, we would require a monitor with a refresh rate of above 100Hz, which brings us to our second requirement, a 120Hz monitor.
120Hz Display
In order to display 60 frames per lens the monitor should have an effective refresh rate of 120Hz, which is where the Samsung 2233RZ comes in, as it's currently the only '3D ready' monitor available. We got the monitor along with the 3D glasses without which the 3D effect is not possible. This is a 22-inch LCD with a native resolution of 1680x1050. The response time of the LCD is a quick 2ms, which is perfect for gaming and of course it supports 120Hz.
Now that we have a 3D ready display, every frame is rendered twice just like the traditional 3D movies, but instead of seeing red and cyan videos, you get the full color spectrum, which is what distinguishes these glasses from home made ones. But in order to draw two frames simultaneously you need a beefy graphics card, which brings us to our third and final requirement, a powerful graphics card.
Graphics card
The third and final requirement to go 3D is a graphics card. The supported cards are 8800GT and above and 9600GT and above, including all the GTX series of course. Since you're going to render each frame twice, the graphics card has to do double the work, so if you want all the eye candy as well in 3D, then you better save up for a good mid-range card. We used a GTX260 (216 shaders) given by Nvidia but we also tried it with a 9600GT to see how it handles it.
