How necessary is is AA with a 1080p resolution?

Post » Tue May 29, 2012 3:30 pm

oh btw.. if you want to figure out your pixel density..

heres a good tool

http://thirdculture.com/joel/shumi/computer/hardware/ppicalc.html

Just punch in your resolution your running and the size of your screen... and violla it'll tell you the density.

Interesting....

So sitting roughly 2 feet from a 28" 1920x1200 screen with a pixel density of 80.86 pixels per inch makes for a most excellent gaming experience.

ps. I typically run 4xAA. 2xAA will do in a pinch, but 4x cleans it up perfectly in Skyrim.

Whether AA is necessary for a 1080p not only depends on the game's engine, but personal preference and how important performance is versus graphics. Jaggies in game don't bother some people. Obviously with out AA, jaggies would be much worse in a lower resolution than 1080p. However, AA is necessary for a 1920x1080 resolution if you want to elliminate jaggies. Sure the higher resolution, the less noticable jaggies but they are alwasy still there. I personally have to use at least 4x MSAA or 8x CSAA, and I run all my games at 1080p. I find this is a good balance between performance and quality of visuals (aka no jaggies). btw, I felt like saying jaggies again. jaggies.

@ OP .

Saw your pic in Whiterun (warmaidens?) and thought ..my game don't look like that....

Wonder if thats...Nvidia verses AMD.....Mods verses No mods? Hmmmm :smile:

I am not using a single texture mod at the moment. With the new update all the texture mods tank my performance. I am ordering a new power supply and taking my PC to a professional to get it OC'd. Afterwards I should be able to run my crossfire no problem and run this game with a ridiculous amount of mods and beyond ultra settings.

IMO, talking about AA without bringing up AF is leaving out half the story. For myself, I tend to get the most acceptable picture when playing with high AF and medium AA.

I don't know why with AA in dungeons on certain angles in shadows/darkness, I get this odd outline around my weapon and think it might have to do with AA, which I turned off again to see if I still get the cyan colored outline around my weapon and shield. It has not since I turned it off (it was on 2xAA).

I usually game on a 1080p projector with the image about 96" x 170" and I have noticed FXAA is fine, not really too much improvement switching to MSAA considering the fps cost.

However, it is a must to use maximum AF and there is very little frame rate cost.

That's the game, not the AA method. I'm not sure why this game has that cartoon like line around things because it's nasty and looks like a cut out.

When dealing with projectors.... specially depending on the projector at high equivilent screen resolutions, the way it's projected actually creates a "FSAA" like appearance naturally.. it's both the benefit and the downfall of using projectors, specially at very large dimensions. Even with a 146" 1080p projector, the effect of fsaa is less noticeable.... it's where hard super high contrasts with per pixel level of detail within a very close range, such as a HDTV or monitor that fsaa is going to be heavily needed...

not saying there isn't any need for it.. just the design of it.

Having run the newer revision of the Panasonic PT-AE7000.... which is considered to be one of the top of the line home theater projectors available today at a cost below that of $4000.... even though it has one hell of a picture.... it doesn't require all that much more FSAA than another screen...

You guys should try supersample AA if you want almost perfect image quality, since it pretty much completely gets rid of texture shimmering, pixel crawling and aliasing on everything on the screen but keeps the image shaper as well. If you can afford SSAA, it's better than 8xAA.

I still like to use AA at 1080. On my 21" Monitor, 1080 with no AA still produces some jagged lines, but they aren't very noticeable. Still, 4x will usually clear it right up, even 2x makes a noitceable difference.

On my 32" 1080p TV, which is what I use for a monitor on my main computer, jagged lines are more noticeable so AA becomes a bit more important to me. I don't usually go higher than 4x though due to performance reasons.

Super sampling AA with edge detect is as good as you can get on modern graphics cards..

and unfortunately most people will dive for 8x fsaa in either multi or adapter sampling thinking it's better than 2x super sampling when actually i'd say it's fairly identical..

both give about the same performance impact to. but i would take super sampling over the others if i had a video card able to manage it at consistant frame rates @ 3240x1920

LOL, At that resolution yeah, you'll need a SLI/Crossfire setup to keep a good frame-rate. :)

4xSSAA image: http://skyrim.nexusmods.com/imageshare/images/3040057-1328122350.jpg

Main things that SSAA does well are the tree branches and bushes which are just about perfectly defined

2x FSAA (2x SS FSAA) http://skyrim.nexusmods.com/imageshare/images/3134504-1327677725.jpg

24x FSAA (8x SS Edge detect FSAA) http://skyrim.nexusmods.com/imageshare/images/3134504-1327072680.jpg

Would be much better if there wasn't a high level of JPEG Compression applied... so keep that in mind.

Pretty dragon, great example of AA gone wild :) Too bad about those POS shadows. I'm a little embarrassed for Beth for that.

It's more the difference between No AF and 16x AF + High Quality Textures. I dunno about AMD cards but on a modernish nVidia card AF has very little impact on performance @ 1080p resolution.

AF has zero impact on ATI cards too... i don't think i run a single game today without it set to 16x AF...

there are tons of games that FORCE the use of a lower AF... that will BYPASS without your realizing it, whatever settings are applied in the driver options for both ati and nvidia.

Mass effect 1 and 2 is a good example.... by default the game typically has trilinear filtering turned off and anisitropic filtering enabled but set at 4x..... and doesn't matter if you try and force 16x or or not.... the game will use 4x only.

Now you might be wondering.. "why would anyone want trilinear filtering, you want anisitropic..."..... this is a misconception or lack of understanding of the filtering technics used for quite some time. Both filters work in tandem with each other, with both enabled, the level of texture detailing and quality is increases significantly.... most tend to go with anisitropic as its better than trilinear by itself.... however why they jump on 4x mode is something i'm not following.. i guess it's the performance version of trilinear.

Anywho long story shorter..... 16x AF + Trilinear = the best textures you can find. Add to that some FSAA and high resolution textures .. there won't be anything better available.

Unfortunately quite often it takes a lot of modifying to get some of those functions working.. and thus far i haven't found a method of enable trilinear in skyrim... which i could....

Yes and both NVIDIA and ATI are known to 'optimise' such methods to gain performance and they done it in the past a few times to get higher benchmarks. It's not secret that idSoftware use AF x4 for RAGE because that's all the consoles can do and their engine is design around them.

At 1080p I can't see a difference after 4x AA. To be honest, transparency AA makes the biggest difference (but also has the biggest performance hit).

Yeah, it's depends on the game but post processing can hide the aliasing but then that's where FXAA is best because it fully AA the object in post process, MSAA in DX9 cannot.

^I get the same blueish outline on my hands, weapons etc when it is dark too. 4xAA (ingame settings) 16xAF (ingame too).

I am sure everyone is well aware of that.

To talk about image quality without also mentioning AF is leaving out an important part of the process.

yah but gotta admit its kind of silly to be talking about the aerodynamics of a car's body work and someone chirps up about the paint job ;) Two equally important aspects of whether or not the final product is 'good looking' to a person, but not entirely intertwined.
