Crossfire Super AA
Hello

first sry for my english...

Can anybody tell me how i can activate Super AA.With RP or CCC

I men the Crossfire Super AA i think its the same like Nvidias SLI AA.

Or is this the same like supersampling??

I find a lot of threads in the www about the crossfire render modi like
AFR,scisor,supertiling and super AA but i cant find any switch in RP ore CCC.

I have two HD7970.

regards

RE: Crossfire Super AA
Short Answer:
Both SLI Anti-aliasing and Super Anti-aliasing have been discontinued.

Long answer:
Alternate Frame Rendering(Where each card takes turns rendering each frame), Super-tiling(Cards render squares in a checkerboard pattern across the screen), and Scissor(Cards render one half of the screen each). These are rendering modes for Crossfired cards and have no direct application to Anti-aliasing. These are used to improve performance.

On the other hand SLI AA is a technique that is used to Improve Image Quality in Games that are limited to a certain framerate (whether because of bottlenecks or other problems). Instead of using the extra GPU to improve framerate, it is instead used to augment the first GPU by rendering an additional Anti-aliasing pass which is then blended into the final frame.

ATI implemented Super Anti-aliasing which was pretty much exactly like SLI AA with a few more options. Unfortunately it appears that both SLI AA and Super AA have been discontinued or at the very least hidden from normal access. Now ATI Tray Tools enabled one to turn on normally hidden Anti-aliasing Modes on AMD\ATI cards. But I can't seem to get ATT working at the moment.

RE: Crossfire Super AA
I don't know if it's working now as I don't have 2 cards to test CF, but as far as I remember, AA 16x (and its variations using EQAA and Edge Detect up to 24x) can be enabled in CCC/RP if CF is detected. That's what you mean by Super AA?

RE: Crossfire Super AA
What a shame.........

Some Games dont have a crossfire Profile ore a profile that dosent work.
Probaly Assassins Creed 3.And the cpu bootleneks realy early.

I would like super aa used to moore image quality to have.
And give the 2nd GPU somthing to do.

Thx for your answer.

RE: Crossfire Super AA
Hello

I tested the AA x16 but its not working as super AA

I tested in both way crossfire on/off

crossfire on +16xAA both GPUs work togeteher in crossfire mode --i see that about the microstutter in AC3sp
crossfire off +16AA only one GPU works together.
I think its like Aether says AMD hidden the switch for the super AA.

When i remeber on my last SLI Rig it was a nice feature for Games they dont run in SLI mode, it would be nice to have that on ATIs too...
Not so dramatic, most Games run fine with two cards, and the other Games runs fine with one card and settings on Medium.

Thx for your answers.....

regards
befor i forget sry for my englisch
