Adaptive AA

conkris · December 30th, 2005, 06:28 PM

I am using NGO 1.5.13 drivers (Ultra Edition with ATT), which are great, BTW, on a ATI X800XL card. The read me shows "Enable Adaptive Anti-Aliasing by Default (Ultra Edition)"

In advanced tweaks under "New AA and AF methods"...."disable support for adaptive AA" was checked. I unchecked it, Which I assume means Adaptive AA is now enabled. I can't say I notice any difference in IQ or FPS (running FEAR). Articles re Adaptive AA indicate it is available for 800 series cards by editing the registry. Does unchecking the box do that, or is it still necessary to do it manually. In previous ATI (CCC) driver versions (5.12)...the Adaptive AA box was greyed out, therefore requiring the registry edit to enable. I never tried it. Sorry if this is a stupid question, but the only way to know is to ask, or try the edit, which I'm really not comfortable with.

Thanks

AAA and HQAF should work even without unchecking the "disable support for adaptive AA" box.

Thanks. That's why I can't see a difference between ckecked and unchecked....heh heh. Too bad there's not a way of comparing AAA "on" vs "off". Just curious if the AAA IQ is worth the performance hit ( I assume there is one). Either way the drivers look and perform great....I'm getting much better IQ and FPS vs ATI's 5.12's. (CCC without AAA). This was my first install of NGO drivers, and it's been very positive. Hopefully future support will continue, which brings me to another question....when updating to future NGO's, is running the "cat-unistaller " sufficient for old driver removal?

Thanks again.

To Enable the Adaptive AntiAliasing and High Quality Anistropic filtering,go to youre ATI Tray Tools Menu,from there go to "Tweak-Advanced Tweaks".Windows will pop out,from "Current Databse" choose "New AA and AF menthods".You will see 3 things:

Disable Support for Adaptive AA

Disable Support for High Quality AF

ASBT

Infront of them are boxes,click on them so they are empty,No little black checkmarks inside,allso make sure they are not Gray.They need to be empty and white.

Hope this helps you

Btw AA only takes like 14% of performance.

Thanks Tango.

Based on the above post by Regeneration, checking or unchecking makes no difference. That was my point. I really didn't see a difference either way. Apparently that's why. AAA and HQAA are "on" regardless. I can live with that, and maybe I was unclear. What I'd like to see is the difference "on" vs "off". Too bad there's not a way to do that. The IQ is great as is the performance, I just like to see what, if anything, I'm "paying" for that quality. Sometimes the performance loss is not worth the IQ gain, Based on you information, the "hit" is not really an issue, so it's no big deal.

Thanks again.

The above says to me it's always "on". I tried it checked and unchecked....don't notice a difference either way, IQ-wise or Performance-wise. So if you know how, please share.

FEAR is a great game IMO. I've only played off line, however. Lot's of places that will make you jump...like bodies falling thru the ceiling. Only problem is....once you've played thru it....you know what to expect. The AI is fantastic, very realistic and unpredicable.
