Okay. So sum this whole article up in a few words...

Assassin's Creed takes advantage of Direct X 10.1 and it shows about 20% in AA performance and better AA quality.

Wow, a 20% improvement with AA enabled in Vista SP1 (DX10.1). It's about time we see some performance and image quality improvements at the same time.

Thats sweet that its actually in use! Too bad Assassins Creed wasnt actually that much fun, lol.

The only problem here is how much horsepower it takes to turn on anti aliasing, even with this effeciency increase.

i think this where ATI will beat NVIDIA, DX10.1 games. All of nvidia latest GPUs are only DX10 compatible

That's rather interesting...

strange, i wonder why this isn't "WOOHOO the first(!!) dx10.1 game!!111"

though what i don't like...
the testing method (comparison section) is.. well.. flawed...
they used a 2900XT for comparison...
a comparison of AA levels and performance
...
they used a card which CANNOT DO AA... so IF it got a performance boost in sp1 other than dx 10.1, it probably still wouldn't show up due to.. sucking so much at what they wanted to see.. lol. i'd like to see a comparison with an 8800/9800 nvidia (even though i know the results would be .. the same lol as it IS the dx10.1, a professional review site should have thought of this... i'm guessing they do ATI only?).

and as it's been confirmed.... well...thats pretty awesome, something that will truly improve both performance AND image quality, almost unheard of haha

ahahahahahahaahah no wonder it isn't "woohoo"

"Ubisoft plans to release a patch for the PC version of Assassin's Creed that addresses the majority of issues reported by fans. In addition to addressing reported glitches, the patch will remove support for DX10.1, since we need to rework its implementation. The performance gains seen by players who are currently playing Assassin's Creed with a DX10.1 graphics card are in large part due to the fact that our implementation removes a render pass during post-effect which is costly."

it's not implemented correctly, the performance increase shoulsn't exist. lol.

hmm... DX10.1, look like some ATi got complete advantage over nvidia in games with DX10.1 support

None of the nVidia cards support DX10.1 , mr. Flinchy .
Anyway ,
apparently the performance increase was in the cost of texture quality
( overall , when playing , it'll still look better with the AA , if you
are about 10 CM away from your monitor ... if not , neither of them
will make a huge difference visually... well... not any noticeable
difference anyway ) .
I sure remember posting this before Flinchy posted his second post... and before wyz135 posted his previous post... wtf?

So, the performance increase was unintentional?

By the way, I remember posting before Kwipper. Oddly enough he posted before me.

@Syndicator
No, the performance increase was intentional, but the glitches and bugs in the game were not intentional and those were happening because of DirectX 10.1.

Also, comments once approved by me appear on the page in order. You can't see comments from other people until I approve them, but after you make a comment you see it right away even though it is not approved. Other people cannot see your comment until I approve it.

@rad yeah i know they're not, i'm meaning test with an 8 series (a powerful AA card) compared to a 2 series ATI (a card which cannot do AA) for the non 10.1 cards.

WTF!!! DX10.1 support removed?? Is DX10.1 really that bad??

They're going to add DX10.1 support in the future. The removal is temporary.

Maybe because of DX10.1 ATi HD3850 can be faster than the 9600GT
