Alpha Texture Enhancment Tweaks

[josh6079]

There are some tweaks that can be made from ATi's Catalyst 6.12 that allow for some alpha texturing improvements (depending on the game of course). In some cases, the image quality is noticably improved, espcecially with alpha texture detail off in the distance. The best part is, from what I hear the performance hit is next to nill or even non-existent.

This is about one of the best summarized posts I've seen concerning the tweak:

I've read about it at these additional places though:

I'll experiment once I get back to the Midwest and at my computer. For the rest of you, have at it!!

Hey, I'm glad you finally got around to posting this since I've been too lazy. It works GREAT! I have Adaptive AA off and have EATM and alphasharpen-whatever on and games run great. I'm playing FarCry with 14xAA, 16xHQAF, Vsync+triple buffering with rock solid 60fps. NEVER dips below 60 :Q

It truely is a great tweak.

Oblivion never looked better!

FYI - this appears to be akin to nVidia's multi-sampling TrAA.

Noob question:
I thought ATi's Performance Adaptive AA was akin to nVidia's MS TrAA and Quality Adaptive AA was akin to nVidia's SS TrAA. Did I think wrong?

Me thought the same.

Isnt this called EATM? I seem to have read this sometime ago though.

Unless you have nHancer and use their combined 16xS. It's kinda like nHancer's Ultra High Quality TrAA. But, it's not exactly supported by nVidia, so I guess it doesn't count. In theory, ATi's methods are equal, but are not quite as good. (AFAIK)

No, ATi's performance AAA still uses super-samples, just less of them than quality, so it'll have a larger performance hit than TrMS but it'll look better.

That's the name of it but from what I've seen it seems to be doing the same thing as TrMS.

It's kinda like nHancer's Ultra High Quality TrAA.

I'm not sure what you're referring to here.

I tried those tweaks and some of my games suffered some glitches I never saw before (such as Age of Empires III and Warhammer 40,000 Dawn of War).
