Ati caught cheating again?

Xtremesystems forums have a thread about Ati drivers not rendering Crysis properly.

this explains why the 5870 beats the GTX480, as its using a combination of bi and tri linear filtering.
 
You do realise that ATI have optimisations built into their drivers which can be completely disabled or activated to 2 different levels? It's called catalyst AI and includes filtering optimisations and shader code for newer games and can be set to disabled, standard or advanced.

ATI isn't cheating at all here so I'd advise you to look towards the website slating it instead of the actual facts behind it lol. If they can't be bothered to use standard/disabled, who's fault is that? Not ATI's...

2007 (MMVII) was a common year that started on a Monday. In the Gregorian calendar, it was the 2007th year of the Common Era, or of Anno Domini; the 7th year of the 3rd millennium and of the 21st century; and the 8th of the 2000s decade.
 
Its not exactly a cheat - but it does mean that comparing 16x AF between and nVidia and ATI system with catalyst AI on means that ATI isn't rendering as high quality filtering.
 
"as its using a combination of bi and tri linear filtering."
Would this even have much of an affect performance wise?
 
Have to see if many other sites pick up on this and see if its as "zomg" as it would first appear to be hyped to be. AF optomisation though probably wouldn't result in much of a gain since the hit is tiny these days for most games.

Typically between 0.9% and 5.87% from what I've seen depending on the game, scene and a few other things - hardly earth shattering. But it does mean that 16x AF comparisions aren't like for like, even if its not going to magically change the performance envelope.

Most people wouldn't even notice the difference while playing probably, but textures are deffinatly not as sharp as they should be and new moire artifacts appear causing shimmer.

I more suprised hardocp never picked up on it as they play through the games for reviews instead of running a canned benchmark. Assuming its actually legit in the first place.
 
Its quite easy to miss if you don't go looking for it. The most obvious is textures with writing/text on them when viewed at a distance especially at certain angles - will still be sharp and readable on nVidia cards but blurry on ATI.
