Question:
Is AA necessary at high resolutions?
wondering if it is or not. Is image quality very different with that on at 1900 res for example?

If you can, why not. It will look more like a movie.

Re: Is AA necessary at high resolutions?
Unless I have a really powerful gfx card, I turn AA off most of the time, or set it low, like 2x. The FPS hit doesn't seem worth the marginally smoother lines. I barely notice it anyways since I'm always moving around in games. And since you're gaming at 1900 res, I'm going to assume you have a really good gfx card so yeah....

Normally, the higher the resolution the less AA you need.

Re: Is AA necessary at high resolutions?
Depends on how close the pixels are together (dpi) e.g. Once newer games (in a few years time lol) start to lag my m9750 (screen dpi:133) I'll turn down/off the AA first thing, since I barely notice the AA anyway on such a dense screen, it doesn't matter how many pixels you have, its how big they are, the bigger the pixel, the more noticable Aliasing is, even on my VAIO (screen dpi: 120~) AA is still pretty much undetectable, unless you have really sharp eyes. Also: AA is most noticable in Space games, where there is a high contrast between a spaceship and the black background, and like Flight Sinulator benefits a lot from AA eye candy wise.
See thread to compare how obvious AA is, I've been on many different screens and resses and at 120dpi+ AA starts to get really unoticable, below around 90-100dpi AA is almost a must because the jaggies are s obvious

Re: Is AA necessary at high resolutions?
I would recommend it on, even at such a high resolution. It doesn't have to be at high settings, like minxshin said, 2X is often sufficient. If your GPU is very powerful, you can turn it up to 4X or 6X, for an even better visual experience. I am aware that the ATI Catalyst Control Center has a feature that evaluates a program, application, game or movie and decides if AA should be turned on, with consideration for your GPU. If it decides it should be turned, it will also decide at which setting. nVidia may very well also have this feature, however, I am not at the moment aware of it.

Re: Is AA necessary at high resolutions?
i agree with you that the benefits of AA depend strongly on the game, and i also agree that generally, as you increase resolution, aliasing is less noticeable anyway, and therefore there is less benefit to antialiasing.
however, i disagree about the correlation between dpi and anti aliasing. dpi doesn't change what is physically being put onto the screen. unless you are at the point where you can no longer see specific pixel detail because the pixels are so small, but that would mean that you could simply use a lower resolution to increase performance without compromising image quality.
imagine a 3200x2000, 13.3" screen.
"The DPI is so high that anti aliasing doesn't matter"
true- but the DPI is so high that you can't see any specific pixel detail at all anyway. you could be running 1600x1000 and not see any difference in the image...
also, aa is often personal preference. i really like 2x aa in a lot of games, but i feel like more than 4x or so actually detracts from quality. its hard to explain, but it makes the edges too soft in my opinion...

Re: Is AA necessary at high resolutions?
The whole point of AA is to fool the eye into thinking a row of little squares is not a stair case but a smooth curve, at sufficient dpi the eye can't detect the individual squares and is also fooled into seeing a smooth curve.

Re: Is AA necessary at high resolutions?
Well going to a higher resolution short of works like AA as it makes the picture sharper in areas it otherwise wouldn't be. But high resolution + AA just looks amazing if your GFX card can handle it.

Re: Is AA necessary at high resolutions?
if the resoulution is a little lower(1200) but you turn on AA will the picture look as great as it would at for example 1900 res?
