The Good The Nvidia 3D Vision 2 glasses have a snug, comfy fit, hold a long charge, and sport the best 3D performance on any PC.

The Bad There's still noticeable crosstalk during games and the $85 price is asking a lot.

The Bottom Line Thanks to its bright images and minimal crosstalk, the Nvidia 3D Vision 2 glasses with Lightboost are the current best 3D solution for gaming and watching movies on the PC.

A few years back, Nvidia released its 3D Vision Kit active 3D solution. At the time, it was the only real choice for 3D PC gaming, but its crushingly dark images and abundant crosstalk were problems. The Nvidia 3D Vision 2, along with Lightboost technology, attempts to address those issues.

Design and features
The Nvidia 3D Vision 2 glasses look less like actual glasses and more like goggles. This can be attributed to the thick brim and endpiece that surround the lenses, as well as the more angular edges compared with the first-gen 3D Vision glasses. In fact, the second-gen glasses sport an almost complete redesign from the first-generation specs. Gone is the glossy, piano-black finish, replaced with a matte, dark gray look that thankfully uses a much more comfortable, softer-feeling plastic.

Also, the handles don't squeeze my head as tightly, but still feel suitably snug when wearing the glasses. The nose pad seems to be slightly wider, with the rubber padding covering more surface area. The first-gen glasses sported a thinner, circular-shaped temple that became really uncomfortable when wearing headphones. On the second-gen glasses, the temple is wider and flatter, with a rubber cushion at the ends, making for a much more comfortable experience.

The power button is now located on on the left endpiece, right in the middle of the gray Nvidia logo. The endpiece is also about twice as long as it was before and the Micro-USB port is still located on the underside of the endpiece.

On my model, the right side of the bar wouldn't stay connected and I had to constantly reconnect it. Very annoying, but a minor quibble.

The 3D Vision 2 glasses are just as heavy as the first-gen model, but thanks to some smart design choices, they feel more comfortable when worn and like any good pair of glasses, you can easily forget they're on your face after a while.

Games performance
I used the Asus VG278H to test the 3D Vision 2 glasses' 3D performance and the Samsung SyncMaster S23A750D as a comparison, using Sasmung's active-3D solution. I set each monitor to 200 candelas per square meter (cd/m2) and used Dragon Age 2 as the chief test game. Initially, the 3D depth on each monitor was adjusted to 50 percent.

Right away I noticed how much brighter images on the Asus' screen were compared with the Samsung, a fact that can be attributed to Nvidia's Lightboost technology. The technology is compatible with both first- and second-gen glasses, but requires a monitor that features Lightboost.

Lightboost controls both the backlight of the display and shutter behavior on the glasses. With non-Lightboost monitors, shutter behavior is less efficient, exemplified by times when each shutter would be closed at the same time during operation. Also, the content being shown on the monitor displays each frame, sequentially, with no pause in between. These characteristics of non-Lightboost tech cause images to both appear dark as well as display noticeable crosstalk.
