I've used an 85Hz monitor for ages. When I look at 60Hz monitors, I can see the flicker and it drives me nuts.But with a 120Hz panel you would see 60Hz on each eye which is usually what most of our panels are now (60Hz) so I'm unsure what you mean about not being able to stand it in the long term.

Same here, 60Hz actually gives me headaches sometimes after longer periods of exposure.
75Hz is acceptable, but still noticably not as stable as it could be and 85Hz is fine for me.
Wrong forum.
This belongs in the Hardware forum.

This has little to do with programmers. DX9 already supports the tech and the programmers don't have to do anything. The *only* thing that has to be done is for the "camera point" to be split into two, and moved 4-5" away from each other - this is all done by enabling 3D in the API, not by programmers writing new code. Then two frames are rendered based on these two cameras.. the "left" and "right" eyes. The shutter glasses are sync'd to the monitor, which alternates between these two camera at each Hz. That's why 120Hz monitors = 60 fps with shutter glasses.

Getting the 3d engine to support the effect in a basic way isn't difficult- doing it in a way which minimises the confusion on the brain is as it's heavily dependant upon the content being shown. For medium-distance content the 4-5" separation may work, as long as you're careful to avoid outlying items which'll render for one eye and not the other which will confuse the brain, ideally you want to prevent objects disappearing from the left and right frame but often this isn't possible. For content at different scales the eye separation distance will often need adjusting to help maintain the effect of 3d without making the scene look unrealistically tiny, an effect which can also happen if there are problems with the heading of the two cameras which are normally are set to converge at a large distance but again this may need changing based on the content being shown.

We're writing programs that are 3D-enabled at work.. nothing "new" needs to be done on our side to be able to fully enjoy this technology. About the only thing we need to do is avoid sprite-based graphics (the billboarding you mentioned), which is outdated anyway. It helps to have everything rendered in 3D - gui, HUD, etc. We're using particle system and shader fire/explosion effects and they look awesome in 3D. Anyway, a sprite-based HUD doesn't look bad though - it looks like a picture frame hung 3 feet from your face, but the 3D effects happen both behind, through, and in front of it.

Billboarding is used a lot in the current generation of 3d technology, it's used to impersonate actual modelled geometry in places where it's impractical to render as many objects as would be needed (The game 'Oblivion' used this technique heavily to allow it to have the dense forests.. [url='http://en.wikipedia.org/wiki/Impostor_%28computer_graphics%29#Move_to_3D']http://en.wikipedia.org/wiki/Impostor_(computer_graphics)#Move_to_3D[/url] ), and the vast majority of particle systems are implemented by using billboards as each particle instance is a textured quad oriented towards the viewer (http://en.wikipedia.org/wiki/Particle_system).
With your use of particle systems displaying well in your tests either you're one of the few not using the textured quad technique, possibly using GPU instancing instead, or the display technology you're using is displaying them a lot better than lenticular or polarized displays are. Viewing content from the Source engine on both of these meant that the particle systems looked great when they were fast-moving such as fire, but really didn't work for the slower moving smoke.
The LCDs don't dim like CRTs do but the lenses in the glasses you're wearing do spend half their time blacked out. The brain does adjust to this as it does if you're wearing sunglasses, and the sudden brightness spike when the shutter clears will help a lot to prevent the eye from undergoing dark adaption- ultimately though each eye's only getting 50% of the light it would if you weren't wearing the glasses which for some people will result in a notable dimming effect.
My understanding is that TFT and CRT are a very different thing.But with a 120Hz panel you would see 60Hz on each eye which is usually what most of our panels are now (60Hz) so I'm unsure what you mean about not being able to stand it in the long term.
On CRT running at 60Hz, the whole image is "redrawn" 60 times per seconds (over simplifying, must be not that simple with interlacing and stuff). If you are sensitive to this kind of effect, you can somehow feel the screen "blinking".
On a TFT, leds that don't change status are just left on or off. The only thing the 60 Hz means is that the screen is able to display a whole new picture every 1/60th of a second. That is why 60Hz TFT are very confortable even to people who consider 60Hz CRT are unstandable.
Now, if you use a 3D system (can be simple obstructing, based on polarisation, or the simple blue/red filters), the strobing is re-introduced either by the goggles, or by the TFT screen that has to re-draw the whole image for each eye. Each eye gets a brand new complete image projected at 60Hz, and the strain is back.
So anyone got this - is it working well ? any feedback on it ? would you mind posting photos of your setup (I expect it looks blurry when screen picture is taken without glasses?) ?
2,3,5 boxing wow with Wow Open Box and MAMA, give them a try!
(was 8 Boxing Wow with HotKeyNet and ISBoxer)
Was streaming on twitch.tv/MooreaTv
This!
Looks amazing but after 3 hours the siezure wasn't!
j/k
Tryed it once at a friends house, got a projector set up for 3D.
Its awsome but after a houer of Colin Mcray i got sick. He can play it for houers whitout feeling anny misscomfort, so i guess its something to get used to.
If you got a video card that suport it, i would try it out.
