With Lightboost, the shutters on each lens alternate more precisely and both are never closed at the same time. Also, in between each frame of the content being shown, the monitor backlight shuts off. These two changes, in conjunction with each other, allows for brighter images with less crosstalk.
However, the proof is in the pudding. With Dragon Age 2, crosstalk was difficult to notice most of the time, but it did rear its head when viewing dark images on light backgrounds. Comparatively, the Samsung displayed much more crosstalk, with consistent and apparent ghosting on the edges of character models. Also, when looking at 3D images on the Samsung, my eyes got fatigued much more quickly. Through the Nvidia lenses there was also a much more dramatic and convincing 3D parallax effect when I viewed the display from different angles.
3D works when it can successfully trick your brain into believing two images are actually one and is usually most successful with polygonal images; however, 2D images that aren't in the actual game environment, like cursors, are usually less convincing. Not surprisingly, viewing the cursor as one image was problematic, causing my eyes to strain and adjust to the new image.
After lowering both monitor's 3D depth down to 25 percent, hardly any ghosting was noticeable on the Nvidia, but I continued seeing double on the Samsung.
I also tested Crysis 2 and Black Ops, and both delivered similar results.
Using the Nvidia solution, the "Three Musketeers" 3D Blu-ray looks bright and sharp and with the 3D depth level set at one, showed virtually no crosstalk. With the depth increased to four, fast moving images are a lot blurrier and I felt more strain on my eyes.
Running the same movie, images on the Samsung were darker, blurrier, and more stressful (on my eyes) to watch.
In order to take advantage of Lightboost, you’ll need a compatible monitor. The Asus VG278H comes with the 3D glasses, as well as a built-in emitter, and is available for about $650. There's a more expensive Acer model as well as a BenQ that’s actually really hard to find in the states from major retailers.
If you already have the first-gen Vision Kit, these glasses will only make a difference in comfort and their ability to block out ambient light -- advantages that may not be worth the extra $85.
3D Vision 2 with LightBoost is the best 3D solution for 3D games. Now we just need to see more monitors made that take advantage of the technology.
