Why doesn't ATI support stereoscopic 3D?

[Magnulus]

Being as NVidia supports this natively (shutter glasses and anaglyph
red-green glasses)?

ATI says this isn't a priority, so they don't support it. But I think
this is mostly because 3D has gotten so little exposure, it could
potentially be very popular. Also, display that can show 3D images without
glasses are now workable, though not inexpensive.

I have been fooling around with a pair of red-blue glasses and an old rig
with a Geforce 4 MX. It works fairly well for Serious Sam, Quake III, etc.
The color is slightly washed out, but if you work up to a higher 3D setting
and configure the filters to match the glasses you are using, alot of color
can still be seen. The computer is so anemic, though, it cannot play newer
games. I use an LCD monitor, and the shutter glasses I tried were somewhat
flickery, even at the highest monitor refresh settings (sort of a "ghosting"
pattern rolling up the screen, and some blurring- CRT apparently works
better for shutters, at least until the response time on LCD's comes up).

I'm interested in 3D glasses because I have strabismus and my optometrist
told me that using 3D glasses with games would strengthen the eye muscles
necessary to see stereoscopicly, without having to spend alot of money on
"vision training". Another option would be to use a red and green or
red-blue filters on the screen coupled with the same color glasses, but I
have had alot less luck finding plastic screens to stick onto a monitor,
without causing the image to look very blurry (I tried some colored
cellophane, but it didn't work well).

the red and blue, and the shutter glass's are different way of doing the
same thing
the red blue trick is the old way, the red side can't see the blue and the
blue can't see the red, so you can have 2 images on 1 screen
the shutter idea is basicly, open left, show image, open right, show image,
however this needs high refresh rate (i can't see them working properly with
LCD's)

most poeple want to use these glass's to improve the game play expeience,
but have never been popular due to lack of support all around really

if you use the shutter glass's which i think came with some nvidia cards you
need a CRT running at high refresh rate (120hz minimum, since it's divided
into to, in effect 60hz, which is kinda sucky, so you want 150hz or better)
not such a huge problem with todays monitors, you just run a low res
