Quite long but a good read.

We have asked our "panel of independent judges" i.e. developers about this method to ensure objectivity of this article and in both cases our developers told us that the description above is a standard technique advocated to gamers by both AMD and nVidia. With the description above being explained to us as "standard", it turns out that the code that was labeled "MSAA Trademark NVIDIA Corporation" was identical to the one recommended by both sides with one very important difference: nVidia's code features a Vendor ID lock that allows for AA menu inside the game only if nVidia hardware is detected.

Quote:

What got AMD seriously aggravated was the fact that the first step of this code is done on all AMD hardware: "'Amusingly', it turns out that the first step is done for all hardware (even ours) whether AA is enabled or not! So it turns out that NVidia's code for adding support for AA is running on our hardware all the time - even though we're not being allowed to run the resolve code!
So… They've not just tied a very ordinary implementation of AA to their h/w, but they've done it in a way which ends up slowing our hardware down (because we're forced to write useless depth values to alpha most of the time...)!"

There are only two conclusions you can make. The First one is the subject of this analysis, Batmangate. After carefully reviewing statements released by all sides, talking to developers, there isn't much left. Forum members on Batman: Arkham Asylum Forums and AMD themselves all changed the vendor ID on their cards and got equal functionality as the one experienced on nVidia cards. This happened at the time when nVidia members both claimed that Batman AA code is proprietary to Eidos and that no vendor ID locks is implemented in the code. "Hands in a cookie jar" is the only parallel we can draw here.

Enabling AA ingame using ati tray tools to get around the vendorID check.

As for performance, a Radeon 4890 from 118 fps to 82 fps with 4x type filtering, while it fell to 69 fps with an identical filtering activated from the drivers.
The impact therefore increases from 41% to 30%, a percentage slightly higher than what we have seen with a GeForce GTX 275 (which goes from 100 to 75 FPS, or a loss of 25%)

on a side note it was shocking to learn that Assassin's Creed dx10.1 support was removed because it *supposedly* broke the game on dx10 nvidia gpu.

If anyone calls this a biased article, skip to the end.

Other than that, it was pretty good.

Though, I will say in ATi/AMD's defense. They are not in a position to just be shoving money out the door left & right for software development. They are in a financial hamper right now. So they are doing the best with what they have.

I'm confused...how is this related to Nvidia catching a break?

P.S. Theo Valich needs to learn to proofread. The second to last paragraph is horribly written.

Regardless of whether or not it was them scheming (it most likely is) it seems like everything they do or try to do, they are always getting caught and slammed. I agree that they completely deserve it, but I have never seen NV make so many boneheaded moves in a row and actually get caught so fast. Seems like they are under extreme scrutiny due to their stupid bashing of others and their own delayed Fermi production.

Alright, that makes more sense. I didn't know if there was something I was missing.

Confirming the worst case scenario in OP.
