this AA stuff seems like bullocks to me. Ive enabled it successfully in every game ive used minus this.

The first two screens are AC in 1680x1050 with multisampling all the way up.

The other two screens (added below.. OC doesnt allow anything past 1600x1200) are AC at 1920x1200 without it. You can definitely tell that its enabled in the first and not the second.

I'll be sure to get more beautiful photos as time goes on. Just took a few quick ones at the beginning of the game.

Okay, here's a comparison shot. It's pretty much the same screen but I couldn't time the jump to be the exact same. And the sun decided to come out. Anyway, you can definitely tell the AA works at non high def res but not anything thats 1080 and up.

I guess ive kinda answered my own question? It appears Assasin's Creed doesn't support AA at any high def resolution. The 9800gx2 IS running AA. It could be that the video card wont run AA at a high resolution, but that does not make sense to me as I am pretty sure its been enabled while im playing COD4 CS:S GOW and Crysis.

Anyway, I hope you're right Mhill2029. 9800gx2 getting better than where its at... awesome! i think its pretty sweet right now

Hey there, I usually hang out at OCF but found this thread on google. I have a GX2 as well, and noticed the same issue. Playing on my small screen at 1280x1024 I could crank the 'multisample' setting to 3, and it ran just fine. Plugging in the 1080p LCD TV disabled the 'multisample' slider. It still looks great from the couch, but it could be better. 360 wired controller works flawless as well.

Did Ubi ever get back to you?

Did anyone with a different graphics card (say a GTX or Ultra) try this game in upper resolutions? Maybe it's a game engine issue, not a 512MB barrier on GX2 problem?

Cheers

According to my sources (whom i shall not name), the GX2 has issues with memory management in it's current form. Upcoming drivers are supposed to address these issues and we will then see what the GX2 is capable of.
This doesn't seem to be accurate. I have read reports of users with SLI'd 8800GTS 640's having the same issue as I have. Their multisampling options are greyed out. And where did you read that the GX2's cannot do AA? Link please?

I have tried this with 8800GTS 640 SLI and have the issue. So it happens with 640MB as well. There doesn't seem to be a 512MB limitation here.

I also have two 9800GTX's and have the same issue with AA in Assassins Creed. I cannot force AA in the driver either. I get no image quality difference, nor do I get a drop in framerates that we would normally expect when turning up AA.

Ubisoft disabled AA at 1920 x 1200. The reason? If they didn't they would probably get a bunch of people complaining about it being poorly optimized, which is what happened to Crysis. When in reality, people are just trying to play at higher settings then their computer can handle.

AC does not support AA at resolutions of about 1600+, you are going to have to force it...console ports...pfft.

Friend has the same thing with his 8600GT. As for the reason, I think, it's 'cause you really wouldn't need it at such a high res.

Found a solution over on [H]..

As is typical for a game ported from a console, there are relatively few graphics options in Assassin's Creed. In fact, there are only four options with which we are concerned. The first is the "Multisampling" option, which simply determines what level of MSAA is used during the rasterization process. The Multisampling option has 3 notches, numbered 1 through 3. At notch 1, MSAA is disabled entirely; at notch 2, 2X MSAA is used; and at notch 3, 4X MSAA is used.


NOTE: At resolutions of 1600x1200 and above, the Multisampling option is automatically set to 1, and the setting is disabled and cannot be changed within the game. However, editing the Assassin.ini file located in the user's windows profile ("C\\Users\\username\\AppData\\Roaming\\Ubisoft\\A ssassin's Creed" for Windows Vista, and "C:\\Documents and Settings\\username\\Application Data\\Ubisoft\\Assassin's Creed" for Windows XP) the setting can be changed, and the game does, in fact, honor the manually adjusted setting. Users should look for the setting reading: Multisampling=0, and adjust the number. Set it to "0" to disable AA, "1" for 2X MSAA, and "2" for 4X MSAA.
