Comments on: Nvidia 3D Vision First Take: So far, so buggy

When playing a 3D Vision-compatible game with the glasses on, the intent is to give the game additional depth.

It's not adding "additional depth", it's adding depth where there was none before.

If you hold your finger up to your nose then close one eye at a time, you will see your finger moving back and forth, because each eye gets a different perspective. The closer to your face an object is, the bigger the perspective difference. Your brain uses this to judge how far away objects are. That's how depth perception works.

So-called "3D" games are actually viewed in 2D. You can't have any real depth perception, because both eyes are seeing the same perceptive of the game world. If you close one eye, you don't lose anything.

These types of glasses let a 2D monitor display *real* stereoscopic 3D. They work by rapidly darkening to cover one eye at a time, while the game renders a unique perspective for each eye. To play a game at 60 FPS, the game must actually render at 120 FPS, rendering two perspectives for each frame. That's why you need a 120Hz monitor.

That "shadow" you are seeing is the one eye getting the perspective of the other (which is why it's more pronounced as the object gets closer to the camera, just like when the finger gets closer to your face). It could be because the monitor is ghosting, or possibly something else. This article would be more useful if you diagnosed what was causing the issue.

I've used shutter glasses on a 120Hz CRT and it's phenomenal. I can hardly wait for this stuff to really go mainstream, so competition can push improvement of the technology.

Yes I agree with someone's story above what he said. I think 3D Vision can be possible harmful to our eyes and brain to look on games all times. Not good for people. Bad news. Many people prefer old ways and like it. I stick old ways.

I stick with Windows XP for many years. No want Vista. Vista have bugger softwares fault inside and make people angry & upset.. Windows XP is stable and more important than Vista. Microsoft is careless making on Vista due to mistake making for rush time.

There are other 3D capable monitors. My 50" samsung does 3D as well. Although I have not tried it the Nvidia glasses should work with it.
