Question about where to set my AA and AF

post #1 of 4
Thread Starter 
Hi,
I just started playing DA2 and i am playing it on DX11 with high texture pack. I was wanting to know what exactly does AA and AF do? if I have to chose to run lower on them, which do I want less of and make the game look great?

Thank you.

Well it depends really...

AF is to do with textures and the distance that the computer starts to lower their detail. So at a higher Anisotropic filtering level your textures will be of a higher detail and resolution (... I can't really remember too much about it) at greater distances away.

Anti aliasing is very very gpu intensive. If you have to choose to run one lower try AA first. Basically it just adds more pixels onto straight lines to make them look straighter. But as it has to do this for every single line on screen the workload is rather large.

If I were you I'd also google the question there are some great articles with picture comparisons of different AA and AF levels. Wikipedia also has good articles on them. Read up!

Simple answer:

AA removes jaggy edges on displayed objects. The higher the AA (4x, 8X, etc.) the smoother edges become, though at the expense of FPS as you go up.

AF makes texture details appear more defined and focused. The higher the better, and at the expense of FPS as you go up.

I'm a image quality freak. I'll gladly take 40+ fps with high AA/AF than 60 fps with less AA/AF. It's all a matter of personal preference, you should find what works for you.

AF will have minimal impact on performance so just leave that at max.

AA will have a huge impact on performance and usually 4x is enough. anything higher is extra work for the gpu.
