All of our image quality comparisons are 200 - 400% zooms on the two highlighted areas of the following image:

What really matters are image quality and performance. Does CSAA provide equivalent or better image quality to MSAA methods? We take a look at Half-Life 2 to find out. First up, we compare CSAA and MSAA in modes where only 4 color/z values are stored.

We can clearly see that, using only 4 sample points, CSAA is able to achieve greater AA quality. Edges are smoother and thin lines appear less broken. But what happens when we look at an MSAA mode with more sample points than CSAA.

Here we can see that NVIDIA's 8x and 8xQ modes provide similar quality. The higher number of multisamples employed by 8xQ does seem to have a positive impact on thin line antialiasing, as seen with the antenna. Edges look about the same though.

    i'm sure there was a lot burried in there ... sorry if it wasn't easy to find.

    8800 gtx and gtx are both no louder than 7900 gtx. 1950 xtx still takes the cake for loudest graphics card around by a long shot -- especially after it heats up in a game.

    My comments in Daily Tech on this subject-

    More "G80" Derivatives in February R
    E: More info would be nice

    If you link VISTA -SANTA ROSA platform-Core2DUO(merom)CPU line up(T7300,7500,7700 models)then a matching Graphics card
    to complete the link.

    So a G80 for laptops/notebooks?

    The pairing of Intels Santa Rosa platform with Vista in the 2Q 07 is next big thing for the first tier notebook manufacturers & all they need is a matching G80 for this setup.

    Unquote-
    Nvidia currently caters to Desktop requirement/needs with the new G80 releases,wonder how the notebook/server versions will be-with Vista ofcourse.

    Vitual memory is probably a good thing for most cases, but in the graphics arena, this *could* potentially make for sloppy/ bad coding practises. Knowing a lot of game devers (some of which actually work for well known companies), I've heard them from time to time complain about maxing a 16x PCI-E pipe. What I'm trying to say here, is that while it would be a good thing for never having to run out of texture memory, but that system memory, and definately the swap disk can not hold a candle to the memory bandwidth that most Video cards are capable of. End result, is that you definately *will* get a performance hit. All this, and we already know the memory bandwidth capabilities of modern PCs, suffice it to say, the most we'll see from current systems is what ? 12-13K GB/s ? Even a 7800GS can do roughly 35 GB/s on card. A 7600GT ? 22GB/s ?

    Still I think Directx10 is a very good thing, and as I didnt read the whole article, perhaps a missed a little ? Reason being, I've been reading about Directx10 since April, and a friend of mine was privy to some of this information after an interview with ATI.

    I don't know how they threading really works, but its quite possible VM support is required in order to allow multiple threads to run without stepping all over each other,. Reply

    Sorry, should read "I don't know how THEIR threading works" Reply

    I don't know what is the problem but I'm really unable to see the images within the latest articles from Anand...Can anyone give me a suggestion? What might be the cause of that?
    The thing is I'm really, really interested in these articles and I need to see those images. Thanks

    Oh, er, then in the options tab of Firefox, (tools->options->content) check the "load images" check box ;) Reply
  • falc0ne - Thursday, November 9, 2006 - link

    well...it would've been simple but I'm afraid is not that...It might be the addblock extension from firefox, other than that I have nooo ideeea...Well I will use the IE tab option instead and load the pages using IE 7. Thanks anyway:) Reply

    Checked the exceptions list ? I know that firefox makes it really simple to block images from a site (to a point of being too easy). Reply
  • JarredWalton - Thursday, November 9, 2006 - link

    If you've got AdBlock on Firefox, press Ctrl+Shift+A and you can see what it's blocking. If it blocks the images.anandtech.com stuff, you can then see which RegEx isn't working right and edit that. Reply
