I was wandering if there's a way to enable in new NV4x cards the "old" 8xS antialiasing method, that was 4xSS + 2xMS as opposed to the "new" 2xMS + 4xMS. I looked into Rivatuner options but currently only one 8xS is listed.

Thanks.

My NV4x Anti Aliasing Investigation (http://www.nvnews.net/vbulletin/showthread.php?t=30641&highlight=Anti+Aliasing)

Information to enable it in rivatuner is here. But its been broken for a long time now. It uses something else thats entirely dumb now.

I downloaded the latest rivatuner. With the drivers 67.66 it let's you pick a 8x which is actually the old 8xS

I've checked the patterns with FSAA-Viewer and they seem correct. I still haven't insatalled any 7x,xx series driver so I cannot say if it works with them.

oh my, i just tried that old 8xs method through nhancer and it has one hell of a performance impact. only good for old games.

4x SSAA (2x2) OGSS is pretty heavy, it renders the image 2x as wide and 2x as high (800x600 = 1600x1200) doesnt it? then resamples that image down to the original resolution, which AAs everything in the image.

The new method uses only 2xSS plus 4xMS (not very stressful on newer generations) but its quality is not up to the "old" 8xS.

2x SSAA can be either 2x1 or 1x2, 2x height or width, either AA horizontal lines or Vertical... as I understand it, dont care much for that really..
So 800x600 would be 1600x600 or 800x1200 then?

It's a 1x2. You can check the various modes with a nice utility called FSAAviewer

Thats not correct. Thats not the old 8xS at all.

I've seen the picture of how the 8xS is supposed to be in your comparison.

It seems that in the recent drivers some samples are missing. I guess there's little I can do save to use the "new" 8xS -_-

Well, if you want to use 2x2 Supersampling, which was offered in the "old" 8xS, you can always use the pure 2x2 SS mode or the 16xS mode.

16xS is 2x2 SS plus 4xMS. It's doesn't cost that much more performance than old 8xS and offers an even better quality.
