Anti-Aliasing

Can someone clear this up for me.
Is it good to have it turned on max in games or left off. or set it in ccc.
most of the videos on youtube showing off games have it turned off. i thought it smoothed everything out?

It does but depending on the game can have a large performance hit. Up to you whether you want to use it or not.

I seem to remember somewhere that they were going to force a 2x AA in DX11? Does that sound right? *goes to do some Googleing*

It looks best on but I would not run it at max. There is little IQ diffrence between max and mid way but there is a large performance drop off. I like to run at x2 or x4 depending on the game.

Have mine on max, leave CC alone.

leave ccc alone as in let the application decide and turn it on in game.

sometimes having it on in ccc has a large performance hit on your system or games

I set it myself game by game. Source stuff, dragon age, killing floor really the less demanding stuff i have it set at x8, everything else like bc2 at x4, crysis at x2.
Game resolution 1920x1080.

Doesn't AA get more noticable with the lower res, so at 1280 x 720 8x AA would be noticed more then if you ran this at 1920 x 1080?

i have my aa set in nvidia control panel to over ride the ingame settings. 16xaa. for the most games look a lot nicer and run great. but yeah as you guys are saying some games dont like it that high. so ingame is a good option.

DarkWhisper · 11 Mar 2010 at 12:10

am @1920/1200

twist3d0n3 · 11 Mar 2010 at 12:12

i don't notice any difference going from 4x to 8x, so generally leave it on 4x unless is starts chugging, then 2x is fine

magicroundabout · 11 Mar 2010 at 12:19

with your setup nothing should chug along

Phoenixdancer · 11 Mar 2010 at 12:24

Lol try running new games at Eyefinity res with AA on, watch it chug!

With eyefinity it does.

Not sure if its running out of vmem or speed or both but a number of games go into single digits or low doubles with aa on + dx11 + eyefinity

It depends not on the resolution but on the pixel density.

1280x1024 on a 17" LCD is roughly the same as 1920x1080 on a 26" LCD.
Both will need higher levels of AA (4-8) to look smooth.

i use 1920 x 1080 on 16xaa, i notice a massive difference between 4 to 8 and 8 to 16.

twist3d0n3 · 11 Mar 2010 at 13:08

as said, eyefinity causes mega chug in things like crysis, dirt 2 with the AA ramped up in eyefinity. on the other hand, l4d2 runs at around 200-250 fps maxed on eyefinity, but that isn't really demanding

forest4 · 11 Mar 2010 at 13:23

It is all about framerate. Most people just prefer a faster framerate than having smooth looking edges. But turn it on if your PC can handle it.

titaniumx3 · 11 Mar 2010 at 14:18

Also many games don't do full scene anti-aliasing, i.e. some edges are still aliased. Battlefield BC2 is a perfect example of this as you can clearly see that some edges for some reason are not being anti-aliased. That said it's still far better than no AA at all and the performance impact is usually very small.

Ideally you'd want supersampling, as that anti-aliases everything, but performance imapact is huge.

Phoenixdancer · 11 Mar 2010 at 14:58

Yea, I would rather have the grass and tree's non-AA and people and building AA then all, performance is Killed when its all on. But boy does it look nice lol
