    Do I get a cookie if it's 16xAA after all? :D

    Ahhhhuh and the R580+ turns out just about 8 fps less hm? No wait it drops from 1x to 4xAA around 50+%, while the G80 drops by 70+%. :roll:

    Dave, my fault, I thought SS2 was still OGL for some reason. Also, I misread the res. :oops:

    Ail, yes, yes you would. And I'm slowly coming around to your POV--no fair my assuming it's a typo, given the performance drop. But disappointing they didn't show more 8x or 16x AA #s. Maybe they're saving those for the NDA. :smile:

    What comes to my mind is several things. Note the 7900GTX at 0 fps. I am going to say that this bench shows HDR plus AA (shown by the red bar) since SS2 does allow HDR plus AA.

    It could say that the X1950XTX is doing 4xAA, and 8800GTX/GTS doing possibly 16xCSAA or maybe normal MSAA.

    No typos i think. Also, the normal bars are the ones using HDR. :grin:

    I didn't say otherwise ;)

    The graph states 4xAA 16xAA; is the X1950XTX capable of 16xAA?

    4xAA for the X1950XTX since it cant perform 16xAA. 8800GTX/GTS performing 16xCSAA, and as someone mentioned, didnt 16xCSAA have the same performance hit as 4xMSAA?

    Maybe they were trying to show this.

    Im just specualating, but who knows :)

    Why are you being so condescending? It's the only test with HDR+AA in the review.

    It is most likely a typo. Even in the text below (you can see that in this article they comment on data after each table) you see "2048x1536 4xAA 16xAF" mentioned. Why would they enable 16x AA here and only here? Why would they label the graph like that? It makes no sense unless it is a typo.

    The likely reason for G80's performance drop is simple: A driver bug doesn't enable framebuffer compression here. HDR+AA without compression needs monstrous amounts of bandwidth (32 bytes per opaque pixel just for colour!). Maybe it's a corner case that was being special cased or debugged for the initial spin of the hardware, and got left behind. SS2 is an ugly game IMO with way exaggerated HDR effects, so I'm not surprised by it being overlooked.

    Don't read much into it.

    (Dave: The 70% drop occurs at all resolutions according to that chart)

    Too bad the t-break review has been pulled in the meantime. There were SS2 tests with 4xAA with and w/o HDR up to 2048*1536. And no the performance drop wasn't nowhere near as much as 70% with 4xAA and HDR.

    Because errors are human and the performance drop sounds more reasonable to be for 16xAA? How hard is it to fetch wrong results when drawing a graph?

    See above.

    well I've seen the ASUS super deluxe double choc neapolitan flavour of any new gen card above 1100 little aussie battlers so that's not too bad.

    I think you are right. ;)

    G80 can do 16xCSAA at 4xMSAA speed. And it can so with HDR. So G80 can do 4xMSAA + HDR at the same speed as 16xCSAA + HDR.

    I vote for a faster card at the $500 price point with the current GTS pushed down to $400.

    The hint in the driver .inf of a 8800 GT, I bet this is the Feb card.

    I'd expect a GX2 much later when they drop to 65nm (if they even do a GX2 style card again).

    GL_NV_gpu_shader4
    GL_EXT_gpu_shader4
    GL_NV_gpu_program4
    GL_NV_transform_feedback
    GL_EXT_transform_feedback
