i'd really like to know how X1900 does with all "newer" AA modi on

[flexy]

i asked that some time ago with the X1800.

I'd be very interested what effect adaptive antialiasing, tranparency aliasing, short: EVERY QUALITY setting at maximum - has on FPS.

The normal benchmarks usually show the numbers for 4xAA or 6xAA, but what about the recent, newer AA methods ati is offering for a while now ?

I know i can "hack" those settings (eg. w/ ati tray tools etc.) and use the new modi even on my old X850XT...but, depending on engine/scene it gets EXTREMELY slow - how does the X1900XT do there ?

XBIT LAB , FIRING SQUAD do really high res/AA/AF benchmarking

I believe with high AA, the R5xx tends to hold up better (especially at 8x) than the G70 cards due to its algorithm and grids.

i think super-aa ONLY applies to crossfire. I am not talking about SLI/crossfire AA-modi.

talking about "adaptive" and transparency antialiasing.

It depends on how many alpha textures are being used, and the performance hit can be large. Hanners shows a more than 50% drop in framerates using 4X Quality adaptive AA over 0AA at 16x12 in CS:S 'Militia' level Link

bit-tech also do it, in a slightly different way though, they find the best playable settings ,and they do apples vs apples at the end

if the cards powerful enough they will test all the way to 2056x1536 or what ever it is with transparency/adaptive AA

Wow, that was a fantastic article.

I cannot believe how much of a difference super adaptive AA makes.
It totally smoothens the image to the point of perfection.
It's a shame the performance hit is so massive aswell though!

Hanners is a great Reviewer IMO, one of the best and my personal favorite.

FYI, Adaptive AA is ATI's version of NV's Transparency AA: different names for roughly equivalent features. So the X1900 will feature AAA, not TAA.

Unless you meant ATI's Temporal AA. In any case, Digit-Life reviewed the X1900 with "HQ" settings: "ATI RADEON X1xxx: AA 6x, plus Adaptive AA, plus Temporal AA, plus AF 16x High Quality mode." They compared it to "HQ" settings on the GF 6/7 series: "NVIDIA GeForce 6xxx/7xxx: AA 8x, plus TAA, plus AF 16x." But keep in mind the GF's 8x (MSAA+SSAA) isn't quite like ATI's 6x (pure MSAA), so it's not quite an "even" comparison, as they're not comparing like for like settings. It's a fair comparison in the sense that they're testing each card's real-world max IQ modes, but know that NV's 8x mode will perform slower (while potentially looking better) due to its SSAA element touching the whole screen (which is redundant, given they're also using TAA, which SSAAs the parts of the screen that most need it). It'd probably be fairer overall to just set the GF6/7 to 4xAA, as it'll give up some IQ but regain a lot of speed.

Oh, and keep in mind that both AAA and TAA have MSAA and SSAA modes. Well, TAA for sure (TMAA and TSAA), and AAA probably (Performance=MSAA and Quality=SSAA, I think). SSAA looks better, but incurs a larger performance hit.
