Is it or is it not true that NV40's are capable of using AA with less of a performance hit then the X800's?

I heard that the X800's have the same performance loss whether you enable AA or AF but on the NV40's AA helps to level out the performance loss from AF.

Is any of that true?

If so, would anyone be willing to do some benchmarks? :)

You could compare the performance at 1600x1200 to 1600x1200 w/ 4x AA on both a 6800 and an X800 and see which has the least performance loss.

Raw AA performance is fairly similar, but as I mentioned in another thread (perhaps you're refering to me ;) ) Nvidia cards usually benefit more when both AA and Aniso are used togeather. Unfortunatly I only have a Ti4200, so my benchmarks would be kinda outdated...perhaps ChrisRay would be willing to do a few more tests for us with his 6800 ;)

Man i feel sorry for that 6800! it must've been through many terrible experinaces since the first time it fell into Chris's hands :(


:p

I dont remember where i was reading about it exactly but i remember seeing it. It would be interesting to benchmark a 6800u and an X800XT PE though and see how each performs at 1600x1200 and then 1600x1200 w/ 4xAA and see how much performance each lost. I know the ATI cards usually handle AF better.

For those of you still wondering whether the 6800's are able to perform 4xAA better then the X800's, here is an answer.

Look at the benchmarks that just run 4xAA.

The answer is definitely YES in the case of the 6800GT vs X800Pro.

6800 Ultra

3dmark03 = 12,849 @default

3dmark03 = 6654 @ 8x AA / 16x AF

Answer your question? :)

OH it's not been so bad, :) I live to gather data and make something useful out of it. I just wonder if anyone actually notices :) Then again I might not even care, I just like investigating things.

1600x1280 resolution is not possible for me though. Monitor limitation.

Hmm, not quite (at least not the question that I was wondering about), especially since 8xS AA also uses 4x Super Sampling. Could you run a 3dmark at defaults, then with 4xAA, then with 16xAF, and then with both? That should at least give a slight indication as to whether or not they reduce the performance hit of eachother on the 6800.

Yeah, we notice, you seem to do it all the damn time :D
