View Full Version : Best AA/AF Combination ?

Hi guys.....Seasons Greetings to you all.

Just wondering if there is any "best" combination of AA/AF.
I read lots of card reviews where they use 2XAA/8XAF and 4XAA/8XAF but curious if anyone has used a different combination e.g. 2XAA/2XAF or 4XAA/4XAF ??
Also what effect overclocking your card has when enabling any of these AA/AF combinations.
I'm thinking of overclocking my FX5900nu to 450/950. Would this be reasonably safe and avoid overheating problems ??

system specs:

P42.8
1gig DDRSDRAM
Albatron FX5900pv (Det 53.03)
XP Pro (SP1)


I've just noticed when typing this thread, that the black fonts seem washed out on the gray background, Never had this problem with previous cards/drivers. Any clues of making it a bit "bolder" in color ??


Many thanks

cheers
Bagman

2X AA and 4X AF seems a good trade-off between performance and quality. The only game that I run that seems to look substantially better with more AA is BF1942- it just begs for 4X or higher. Recommend playing with the settings yourself to find your comfort zone as every PC will have different limitations.

I have a 9800 XT and what I do is that I usually start out at 6xAA/16xAF at 1280x1024/1280x960.
If that doesn't work out well I first try lowering AF to 8x, if that doesn't work I lower AA to 4x.
If I still can't get proper framerates I drop down AA to 2x.

At 2x/8x basically any game is playable at 1280x0124/1820x960 on a modern high end board so usually I never go below this.

Though there are exceptions to my "rule". Some games are very fillrate intensive (UT2003 for an example) here it will make more sense to lower the resolution as a first step when trying to solve performance issues.
For an example 1024x768 with 6x FSAA is much faster than 1600x1200 without FSAA in UT2003.

Since I'm a pretty lazy guy I usually just keep my settings at 4xAA/8xAF and adjust the resolution for each game to make them all playable without having to alter control panel options for the videocard each time I want to play a different game.

Personally I can't stand anything below 1024x768 with 4x AA and 4x AF or 1280x960 with 2x AA and 4x AF.

I use A tuner to enable 4S AA and use that with 4xAF, and yes I am never below 1280x960....

I leave it on 2XAA/4XAF and use the highest res playable.. which is usually 1600x1200..
I have a 21" so 1024x768 looks crappy

I could never stand the low fps

It honestly depends on the game. Lemme just a give you a few games and the AA/AF I use along with framerate. Please note, all of these games are with max settings.

LOMAC - 4x/2x - 45fps
CoD - 4x/4x - I dunno but I would estimate 35-55fps
Raven Shield - 4x/2x - 60fps
Planetside - 2x/2x - 45-90fps - Just depends on the size of the battle (no less than 25 at any time).
CFS3 - 2x/2x - 50-70fps
AA:O - 4x/2x - 45-65fps
FS2004 - 6x/4x - 30-40fps - All depends on the weather and the plane. Can dip to 15, but never anything less.

Just depends on what you like and what you are willing to compromise on. These are what I prefer and are about the best frames I can get with the settings that look the best. Obviously some of these could be stepped up, but I am happy with what I get and how the game looks.

Video cards don't operate in a vacuum. This one does just fine at 535/1.01.

Still, I can't stand the fps I'm getting with those settings on my 5950 Ultra, certainly not my 5700 Ultra.
I'm not saying you don't, I'm just saying were surely must have a very different barrier where playability becomes a concern.

Honestly, I can't see myself not using a 256-bit bus card any more. Games like Halo that rely on fillrate are barely playable on cards like the 5700 Ultra at 1024x768 whereas on my 5900NU, at this same resolution the game plays as smooth as can be.

I agree whole-heartedly. I am running a 9800 pro and 4x AA is pretty much always do-able, while 8x aniso has proven, on my system, to give me the highest image quality possible for the lowest performance penalty (most bang for buck). It seems that simply sliding into the most acceptable resolution is the best way to get the performance tradoff handled.

Myself, using a Radeon 9800 Pro, I run at 4x AA/16x AF, then change the resolution as required. For multiplayer games like UT2003, I tend to run at 1024x768 to ensure there is never any dip in frame rates (a couple of intensive levels like Face3 keep you at these settings, without them you could use 6x AA 1024x768), while for most single-player games I tend to use 1280x960 with those same settings.

Mind you, I've recently picked up RadLinker which allows me to change my settings on a per-application basis (bloody useful for things like Halo which don't use AA, but causes a performance hit when on anyway).

Anyway, 4x AA, 16x AF, with varying resolutions depending on app. I consider myself very sensitive to FPS, so the settings here are most playable.
