3d vision

ok, i have had a look on nvidia site and it says my 9800gtx+ has this feature, so i wondered do you need their 3d vision kit or would standard red/blue 3d glasses give the same effect, maybe a little poorer but still 3d.
this then led me to read a bit more into it, never finding the answer to my original question

, and finding out you need a 120hz screen for it to work.
now this then led me to another thought. we have a few films in 3d, some blue ray and some standard dvds, which in all fairness are rubbish. the 3d is there, but 99% of the time there is a horrid green tint on everything, occassionally the true color flashes in and out. which made me wonder, is this down to the fact my tv isnt 120hz and all 3d technology requires this kind of refresh rate.
so in essance, i have tried these films both on my ps3 and pc and get the same problem. so if anyone can answer any or all of my questions i would be really greatfull. cheers

The 120hz is required on 3d systems that use shuttered glasses so that even displaying alternate frames for each eye, you still get an effective refresh rate of 60hz.

This does not apply with the red/blue glasses as the both frames are displayed at once, but in different colours. The glasses filter out the correct image for each eye.

So in short - the horrid colour problem is inherent to the red/blue system (or anaglyph to give it its correct name).

Does that answer your question?

ah right, yeah it does, so why make the 3d films if its that poor?
also can yu clarify the first thing that lead me down this road, if i enabled the 3d vision setting on my gfx card, would it work with the standard 3d glasses or do you need the shuttered glasses?

Looking at the NV site, you can use the older glasses, but with a more limited effect..

Well, most of the 3d films are originally made to be used with one of the better systems - e.g. the one in cinemas which uses differently polarised light. They often bundle the anaglyph versions on discs as a selling point. I agree, though - they're pretty rubbish.

3D vision is intended to work with the shuttered glasses...although I think there might be an anaglyph mode in the drivers. I'll have a look when I'm next at my PC. Even if it's there, you'll obviously have to put up with the horrible colours.

ok cheers for that, so overall unless i pay £100+ for the shutter glasses and buy a new 120hz tv then there is no point looking at going 3d?

I reckon so.

Having said that, I'm going to try the anaglyph setup on my machine just to see how machine handles it.

I'm seriously considering going with the full 120hz setup, but I can't really afford it.

Exactly, and even then Nvidia 3D eats up framerates - so you will get much worse framrates than you currently do. It may even require a GPU upgrade to play modern games, at high res and in 3D. All-in-all a very expensive upgrade.

I tried the Nvidia 3D discover a few months ago - it halved my framerates and wasn't that impressive. Some games like left 4 dead worked OK - but I still far prefer it in 2D to crappy anlygraph 3D.

I see the merit in 3D - and I hear the proper shutter glasses 3D is far superior. But for the cost of the expensive system and a proper 120Hz TV, I can't justify the price to myself.

yeah think i have to agree, seemed like a good idea, and when the 3d films do flicker in real color rather than tinted then they do look good, but its damn annoying that its such a poor system at the moment for the films they are heavily advertising in 3d.
