GeForce 3D Vision COD4

Does GeForce 3D Vision doesnot support laptops?
I went throught the website and couldnot see the mobile graphics card on the list. Any one have some info about this?

 

I think one problem would be the refresh rate of most LCD's on laptops... I believe for proper image quality (ie no flicker), you need to run the monitor at 120hz refresh rate as opposed to the normal 60... as for driver and or other issues not sure.

 

Not to mention even the 9800M GTX would get slammed running stereo. You'd have to turn everything to the minimum and even then it'd be choppy in some games.

 

Be77solo your right about the 120hz.

 

is there a LCD monitor that support 120hz refresh rate? i thought the maximum they can go is about 75hz?

 

They have 120HZ LCD televisions, so im assuming it wouldnt be to hard for them to port that into a smaller screen

 

lcds have a constant lightsource, so you shouldn't get any flicker... cathode ray tube monitors don't, so that's why you get flicker at low refresh rates....

 

Knew I read it somewhere, check this thread out, it mentions the 120hz problem:

"Stereoscopic 3D gaming actually took a step backward when PC manufacturers switched from CRT monitors to LCD monitors. The original 3D shutter glasses released years ago worked well with CRT monitors because the old displays had superior refresh rates that could handle stereoscopic gaming, but current LCD monitors don't work as well because they are locked at 60Hz. Fortunately, LCD-monitor manufacturers including Samsung and Viewsonic are preparing to release 120Hz displays that are able to supply the refresh rates necessary for flicker-free stereoscopic playback."

That appears to be the biggest issue I see other than possible poor performance frame rate wise as mentioned above.

 

To me, the whole design looks overly complicated and flawed. They could make 3D work with a simple IR receiver and emitter, I don't see the need for all of this. It could work with all hardware, any display and cost about 1-5$ to produce. A simple IR diode that you wear on your head that's tracked by a IR receiver, or webcam running 60Hz, and have the game's camera adjust according to head movement. Granted it would only work with one person, and games would have to support it, but I don't see why not.

Wouldn't this method that nVidia is trying to use require the GPU to render the game at 120FPS with vsync to match the refresh rate? Sounds like too much to me.. I guess I'll wait some more til it's publically available and see what those of you who bought it think..
