What is the max anti-aliasing you can on CCC with a 4870x2?

[Isaac MM]

I am completely confused. Today i got an error with Catalyst, my screen froze, i reset the pc and when i logged into Windows i found out Catalyst driver was no longer working. I formated Windows and installed Catalyst again, everything worked normal, except that before i could set 16x anti-aliasing on CCC and now the max is 8x?

After some research, i couldn't find any mention of anyone setting anti-aliasing 16x on CCC, i even checked some reviews and they all would use a max of 8x AA.

Wth? Am i the only person who was once able to set 16x AA on CCC? So if you own a 4870x2, please post the max AA you can enable on CCC.

You have to change the filter type. Regular (box) FSAA is limited to 8x, while the other filters like narrow tent, wide tent, and edge detect will allow you to choose higher options (at a large performance hit at times too). Your max FSAA samples should be 24x if you use the edge detect filter.

I know that, i could set 16x using Box.

I believe you are mistaken, box fsaa is limited to 8x.

AT tested the FSAA modes of the RV770 here:

I am 100% sure that i could enable 16x Box AA. I remember it as clear as day that i would change it to 16x to play Prototype, using Catalyst 9.6. I was always able to do this, since i bought this card like a year ago.

The x16 box AA is actually their Super-AA setting, where each GPU is using x8 multi-sampling with different positions -- then combined to offer x16 multi-sampling.

Perhaps CrossFire isn't working for some reason or another?

I can set box to 16. This on 9.5. "http://i190.photobucket.com/al...2/Majic7_photo/ATI.jpg"

Yeah, but it sucks they don't offset the texture/shader samples. Then they go offer 32x which simply adds a horrid wide tent filter to 16xAA. :thumbsdown:

I guess CrossFire isn't working then. I have formatted Windows and tried a bunch of different drivers and it is still the same, i don't know what to do anymore. Maybe my card has gone bad?

Download RivaTuner from Guru3D and use the hardware monitor. Open a game and see if both GPUs are running. If you don't have dual monitors it will do a log graph in the background, long enough to see if both of them are running right. If it's totaly screwed it may tell you without running a game.

It bothered me a bit as well. The older x10 and x14 AA settings with older CrossFire products offered exceptional quality and the super-sampled aspect was virtually for free. Great quality for its time.

It's truly wonderful to have hybrid flexibility for certain titles in my mind-set. Some like to knock nVidia but certainly appreciate this ability on their hardware very much so.
