You'll need the 5.9 Cats

THE LOWDOWN

For those who don't know what Transparency AA is:
Games sometimes use textures instead of polygons because it's cheaper (to process) and easier. Leaves on trees are often done this way. Anyway, with transparent textures, the texels in the texture have hard edges of transparency. One texel is transparent, the next isnt. When these texels get scaled up and rendered, you see jaggies on the screen which are not taken care of by normal antialiasing because they are not a polygonal edge.

Transparency AA fixes this by supersampling the texture with the background, providing smooth textures as well as polygonal edges.

The result is that ALL jaggies are gone. You may have noticed in some games like HL2 or BF2 that leaves and other foliage, maybe some railings often have jaggies even when FSAA is on. This is the solution.

And it works with every ATi card from 9X00 onwards with a small performance hit that is only taken when transparent textures on being displayed.

THE HACK:

Change the ASTT_NA setting to 0.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Video\{5A61609A-036A-4D32-B447-F0E42DA9714D}\0000

5A61609A-036A-4D32-B447-F0E42DA9714D this number is different for everyone, you will probably have more than one in the /Video/ subset. You can tell which ones you need to change by checking what the CatalystVersion is in the /0000/ subset (you only need to change the ones where CatalystVersion is 5.9). I had two of these big number subsets to change. You may have multiple numbers at the location because of multiple driver installation but only one is active. To be sure just change the value in every one that is 5.9.

Now you have to do a driver refresh by manually changing the AA or AF settings in the tray icon or in CCC. The screen should flicker black and then the icons rebuild. Now check in the tray icon, "Adaptive AA" should now be an option you can turn on under antialiasing. The same option will be in the CCC options.

ADAPTIVE AA ROCKS.

I feel bad for all you 6800 folks as it seems nVidia is only providing for Transparency AA on the 7800 series while pretty much everyone with an ATi gets it.

ENJOY! This finally makes AA worth it, especially in HL2.

Screenshot of it in action:




Edit: moments later I realized there were screens in the link, but it doesn't hurt having an example here with the summary

I've always wondered if there was a way to fix this. Too bad my card sucks.

TSAA in nV cards seems to work a lot better, though there's problems with both and fences in BF2. The only nV card to offfer it is the 7800 so far, though.

Now, do I have to keep AA on and click Transparent AA, or can I click the Transparet AA button, and still click on "Let-the application control"

Makes WoW look amazing on my 9800 Pro, I'm testing Ghost Recon now.

EDIT: Makes the foliage in GR look amazing too.

Wow, that difference is like photograph|game.
^ Wow, I just posted something that's obvious!
^ Wow, I did it again!
^ Infinity

I think if you let application control it does the TSAA to a matching level. Havent checked though

Those pictures look awesome. Is it worth enabling on older cards like the 9600 pro and X700 mobile?

You'll have to try it for yourself to see. I run CS:S at 1280x1024 All high settings 4xFSAA ATAA 8xAF and never go below 40 fps on my 9800 pro...

The article mentions that it cause about a 10fps performance drop. How has this compared to your experiences with this? Particularly in games like WoW where say a 10fps drop in Ironforge would reduce framerate to 0..

I just bought a new custom PC. It's got an ATI 9600 XT. Anyone know if that's any good?

Not good.

Yeah, it's mediocre anymore.

Hmmm it doesn't seem to be working with my 9600 pro 128 mb.

I did the hack, turned it on, but railings are just as bad.

I'm trying with Call of Duty or Splinter cell, dunno if it has anything to do with the game.

Never mind, it MUST be game related as it was working most exceptionally well in Call of Duty 2 demo

SC doesn't behave well with antialiasing if i remember correctly

Pretty nifty.

has to do with the fact that it uses DX8 post processing effects...

Ya no kidding, Splinter Cell is downright horrible. I mean, come on, I'm running at 1600xwtvr res with 6x antialiasing and its still jaggy as **** lol

that's because AA doesn't work with DX8 post processing

So basically, anything thats DX8 and below is worthless?

Awww I find this out as I'm getting rid of my computer and moving to consoles ;_;

Nope. Any DX game will work with it, but there are a few exceptions.

Well, I have a new love in my life, and her name is Adaptive AA.

another way to get adaptive AA is to use ati tray tools

Do anyone overclock their ATI cards? If so, what programs do you use? I use something called ATItool but I don't really feel all that safe with it. lol

Jep

ATITool's automatic overclock is pretty safe. It does alot of testing.

*cough*BATTLEFIELD2THOSEFSCKERSATDICE*cough*

ermm may want to edit that

I know nothing. >_>

Auto-overclocker's suck. Hardcore testing ftw \m/

Note that this quick hack works in the new 5.10 drivers also.
