No AA in Bioshock for ATi till ?

As it stands now, AA only works in BioShock’s DX9 mode, and only with GeForce hardware. We tried forcing AA with the Radeon HD 2900 XT under both Windows Vista and WinXP with all four custom filter AA modes (including edge detect) and couldn’t get AA to work properly in BioShock. We asked AMD if they plan on adding AA support to BioShock in a future Catalyst driver revision but couldn’t get a direct answer. The only way to enable AA under BioShock with Radeon cards is to rename the BioShock executable from “bioshock.exe” to “Oblivion.exe”. Keep in mind by doing this though, AMD’s driver-level optimizations for the game are automatically disabled, and as a result, performance suffers – we recorded a frame rate of just 26.7 fps for the 2900 XT with the executable renamed to Oblivion.exe running our manual walkthrough sequence under 4xAA at 1600x1200. (Surprisingly enough, the Radeon X1950 Pro delivered a frame rate of 20.9 fps under the exact same scenario) Because of this, AMD’s Dave Baumann told us flat out not to run the game with the renamed executable.

Looks like Bioshock is going to force new driver releases out of both AMD and nVidia....

TBH i haven't got AA on in bioshock but then at 1600x1200 it's not really a big issue.

Well strangely enough the only way you can run FSAA is by forceing it at a driver level, face it they don't want you to run FSAA.
Although I'm not really that surprised as FSAA basically works by rendering each frame multiple times then layering the resaults together. As such it can have a major impact on performance.

FSAA is pointless for high resolution displays anyway.

I only run in 1280x1024 and don't even notice the lack of FSAA.

[Pob255]

I did notice it or the lack of (most in games I happly run at 1280x1024 FSAAx2) but only when I looked for it.
Most of the time the lack of FSAA is hidden in the gloom, I do hope we're not going back to the days of haveing to turn up the gama on every game just so you can see to play it.

I don't know what you call "high resolution" but my 2405FPW runs at 19X12 and I always use AA.

The screen shots on page 1 of the article show why, the jagged edges of the table, and the stairs, make the scene less realistic.

It's true the jaggies get smaller as resolution goes up, but they don't go away.

I guess the point is: why would you want a card that doesn't give you the option in a usable fashion if you're considering buying a XT or a GTS?

I /used/ to think that

They should have used shader based AA (he says, not knowing the details). Notice how as soon as you die in the game (he says, this time speaking from experience, lots of it) all the jaggies go away as it gradually blurs the image.
